How to hover each cell for each day with react FullCalendar? - reactjs

I have a Reactjs FullCalendar and I want when, I hover the cell of the days, the background will be blue also, the time of this cell will be appeared.
I try this :
.fc-widget-content td:hover {
background-color: blue;
}
But, I get :

But, I want, to hover each cell for each day independently like this:
https://i.stack.imgur.com/v9FSh.gif
His code is:
<td onmouseover="highlightBG(this);" onmouseout="nohighlightBG(this);" style="color: transparent; height: 1.5em; text-align: right; padding-right: 2px; background-color: initial;"><span style="font-weight:900;">8:35</span></td>
function highlightBG(element) {
element.style.backgroundColor = '#39b6f0';
element.style.color = 'black';
}
function nohighlightBG(element) {
element.style.backgroundColor = 'initial';
element.style.color = 'transparent';
}
How can I fix it ?

This can be achieved using Jquery and Fullcalendar like this:
$(this).children("td").each(function () {
$(this).hover(function () {
$(this).html('<div class="current-time">' + $(this).parent().parent().data("time").substring(0, 5) + "</div>")
}, function () {
$(this).html("")
})
})
}
},
function () {
$(this).children(".temp-cell").remove()
}): $(".fc-widget-content:not(.fc-axis)").hover(function () {
$(this).html() || ($(this).append('<td class="temp-cell" style="border: 0px; width:' + (Number($(".fc-day").width()) + 3) + 'px"></td>'), $(this).children("td").each(function () {
$(this).hover(function () {
$(this).html('<div class="current-time">' + $(this).parent().parent().data("time").substring(0, 5) + "</div>")
}, function () {
$(this).html("")
})
}))
}, function () {
$(this).children(".temp-cell").remove()
})
}
})
this will append td cells to the whole horizontal line and you can simply have the time or hover any color you wish.

AngularJS - NVDA screen reader not finding names of child elements

Apologies for the bare-bones HTML here...
I've got some AngularJS components that are rendering this HTML for a multiselectable dropdown:
<ul role="listbox">
<li>
<div ng-attr-id="ui-select-choices-row-{{ $select.generatedId }}-{{$index}}" class="ui-select-choices-row ng-scope" ng-class="{active: $select.isActive(this), disabled: $select.isDisabled(this)}" role="option" ng-repeat="opt in $select.items" ng-if="$select.open" ng-click="$select.select(opt,$select.skipFocusser,$event)" tabindex="0" id="ui-select-choices-row-0-1" style="">
<a href="" class="ui-select-choices-row-inner" uis-transclude-append="">
<span ng-class="{'strikethrough' : rendererInactive(opt)}" title="ALBANY" aria-label="ALBANY" class="ng-binding ng-scope">ALBANY</span>
</a>
</div>
(a hundred or so more options in similar divs)
</li>
</ul>
What we need is for screen reading software to speak aloud each option as it's highlighted via arrow key navigation. As it is now, NVDA says "blank" when keying through the list. If, in the directive we're using to create this HTML, I add role="presentation" to the <ul>, then NVDA will recite the entire list of options as soon as the dropdown opens, but not individually for each arrow key keystroke (and after hitting Escape to make it stop talking, keying through the options says "blank" again).
I keep thinking that the listbox and option roles are in the correct places, but is something else in the structure preventing the screen reader from finding the values correctly?
This answer got quite long, the first 3 points are most likely the problem, the rest are other considerations / observations
There are a few things that are likely to cause this issue, although without seeing the generated HTML rather than the Angular Source there could be others.
Most likely culprit is that your anchors are not valid. You cannot have a blank href (href="") for it to be valid. Looking at your source code could you not remove this and adjust your CSS or change it to a <div>?
Second most likely culprit is that role="option" should be on the direct children on role="listbox". Move it to your <li>s and make them selectable with tabindex="-1" (see below point on tabindex="0") instead. (in fact why not simply remove the surrounding <div> and apply all of your angular directives to the <li> directly).
Third most likely culprit is the fact that aria-label is not needed and may in fact be interfering, a screen reader will read the text within your <span> without this. Golden rule - do not use aria unless you can't portray the information another way.
You also need to add aria-selected="true" (or false) to each <li role="option"> to indicate whether an item is selected or not.
Also you should add aria-multiselectable="true" to the <ul> to indicate it is a multi select.
While you are at it, remove the title attribute, it doesn't add anything useful here.
aria-activedescendant="id" should be used to indicate which item is currently focused.
Be careful with tabindex="0" - I can't see if this is applied to everything but really it should be tabindex="-1" and you programatically manage focus as otherwise users could tab to items that they aren't meant to. tabindex="0" should be on the main <ul>.
Due to the complex nature of multi-selects you would be much better using a group of checkboxes as they provide a lot of the functionality for free, but that is just a suggestion.
The following example I found on codepen.io covers 95% of everything if you use a checkbox instead and would be a good base for you to pick apart and adapt to your needs, as you can see checkboxes make life a lot easier as all the selected not selected functionality is built in.

Also you will see that gov.uk uses a checkbox pattern (within the organisation filter on the left on the linked page) for their multi-selects (with a filter - something you may consider with 100 different options as they have highlighted some key concerns in this article).
As you can see (and I wasn't finished) there is a lot to consider.
Hope I haven't scared you too much and the first few points solve the issue you originally asked about!

ionic 2 calendar cssClass not working

I'm using https://github.com/HsuanXyz/ion2-calendar to generate a calendar in ionic. I can't make color changes to dates using dateconfig's cssClass.
Below is the code i'm using
` daysConfig() {
let _daysConfig = [
{
date:new Date(2018,0,1),
subTitle:'New Year\'s',
marked:false,
cssClass: 'my-cal'
},
{
date:new Date(2017,1,14),
subTitle:'Valentine\'s',
disable:true
},
{
date:new Date(2017,3,1),
subTitle:'April Fools',
marked:true
},
{
date:new Date(2017,3,7),
subTitle:'World Health',
marked:true
},
{
date:new Date(2017,4,31),
subTitle:'No-Smoking',
marked:true
},
{
date:new Date(2017,5,1),
subTitle:'Children\'s',
marked:true
}
];
_daysConfig.push(...this.days);
this.calendarCtrl.openCalendar({
from: new Date(2017,0,1),
to : new Date(2018,11.1),
daysConfig:_daysConfig
})
.then( (res:any) => { console.log(res) })
.catch( () => {} )
}`
css Class
.my-cal {
color: yellow
}
After a long RnD of almost 5 hour could solve this issue.
Please find the below solution in ionic
Define the below class in global.scss
.my-cal {
background-color: red !important;
}
and remember not to define this class anywhere else.
now use this in you days config as below:
let _daysConfig: DayConfig[] = [];
for (let i = 0; i < 31; i++) {
_daysConfig.push({
date: new Date(2020, 4, i + 1),
marked: false,
subTitle: `$${i + 1}`,
cssClass: 'my-cal'
})
}
Hope it will help someone :)
I just encountered the same problem, and I solved it by adding the follow style in the .scss file:
button.days-btn.my-cal {
p, small {
color: yellow;
text-decoration: underline;
font-weight: bold;
}
}
The cssClass is only added to the button that the <p> element containing the text is in.
So to properly change the color, you'll have to reference the <p> element first and assign the color to that.
Example
.ts
cssClass: 'my-cal'
.scss
.my-cal {
p {
color: green;
}
}
One of the solutions would be to add this code to your global scss/css style
ion-calendar { .my-cal{ background-color: #6E6B6B !important; p{ color: white !important; } }}
Later add "my-cal" class to wanted day.

Angular - how to make $interval work from user input

I am taking date and time from user as input and then wanted to display it interval in label
After that datetime completes I want to make that label color change.
Please guide me how can i achieve this.
https://codepen.io/shreyag020/pen/vKvmdx
$interval(function(){
todoTime=$scope.datetime;
});
Here is an example of how you could change the background color of a div over time. Clicking the start button begins a countdown timer from 1 minute. It starts out with no background, once the timer is started it turns green, at 15 seconds before time runs out it turns orange and when the time has run out it turns red. The change of the background color is animated using ng-class, ngAnimate and the animation hooks.
angular.module('app', ['ngAnimate'])
.controller('ctrl', function($scope, $interval) {
var timerPromise;
$scope.reset = function() {
$scope.userTime = new Date;
$scope.userTime.setMinutes(1);
$scope.userTime.setSeconds(0);
$scope.resetVisible = false;
$scope.started = false;
}
$scope.start = function() {
$scope.started = true;
$scope.resetVisible = false;
timerPromise = $interval(function() {
if ($scope.userTime.getSeconds() > 0 || $scope.userTime.getMinutes() > 0) {
$scope.userTime.setTime($scope.userTime.getTime() - 1000);
}
}, 1000);
}
$scope.pause = function() {
$interval.cancel(timerPromise);
$scope.started = false;
$scope.resetVisible = true;
}
$scope.timeBackground = function() {
if ($scope.started) {
if ($scope.userTime.getMinutes() === 0 && $scope.userTime.getSeconds() === 0) {
$scope.resetVisible = true;
$interval.cancel(timerPromise);
return 'expired';
}
if ($scope.userTime.getMinutes() === 0 && $scope.userTime.getSeconds() <= 15) {
return 'warning';
}
return 'ok';
}
return 'clear';
}
$scope.reset();
});

create a decimal star rating for a comment in angularjs

Here is a code which present star rating code in angularjs. In some point I need to have a average of all the rating in whole the system so instead of rate:2 , i will have 2.4 . In such case i am interesting to present 2 star which are complete fill and one which has only half filled. How can I change my code in order to add this functionality?
Moreover, initially I would like to don't specify any star filled. That's also need a modification which I am not sure how should be done?
<div ng-app="app" ng-controller="RatingCtrl" class="container">
<h1>Angular Star Rating Directive</h1>
<div star-rating ng-model="rating1" max="10" on-rating-selected="rateFunction(rating)"></div>
<star-rating ng-model="rating2" readonly="isReadonly"></star-rating>
<label>
<input type="checkbox" ng-model="isReadonly" /> Is Readonly
</label>
<div><strong>Rating 1:</strong> {{rating1}}</div>
<div><strong>Rating 2:</strong> {{rating2}}</div>
</div>
In my directive
angular.module("app", [])
.controller("RatingCtrl", function($scope) {
$scope.rating1 = 1;
$scope.rating2 = 2;
$scope.isReadonly = true;
$scope.rateFunction = function(rating) {
console.log("Rating selected: " + rating);
};
})

},
link : function(scope, elem, attrs) {

function updateStars() {
scope.stars = [];
for (var i = 0; i < scope.max; i++) {
scope.stars.push({

});
}
};
scope.toggle = function(index) {
if (scope.readonly == undefined || scope.readonly == false){
scope.ratingValue = index + 1;
scope.onRatingSelected({
rating: index + 1
});
}
};
scope.$watch("ratingValue", function(oldVal, newVal) {
if (newVal) { updateStars(); }
});
}
};
});
and css
.rating {
margin: 0;
padding: 0;
display: inline-block;
}
.rating li {
padding: 1px;

}
.rating li.filled {

}
.rating.readonly li.filled {
color: #666;
}

Thank you for any help.
You could use two identical set of stars to achieve this, position absolute one on top of the other. One fills your background star shapes (gray) and the one position at the top will represent your fill.
The top set of stars are all filled but its container's width can be adjusted to the proportion of stars representing your rate.
var score = 2.4;
var maxStars = 5;
var starContainerMaxWidth = 100; //pixls
var filledInStarsContainerWidth = score / maxStars * starsMaxWidth;
A CSS overflow hidden will hide the portion of stars that are not turned on, in effect allowing you to show 2.4 stars filled.
Update:
I have bashed a quick example http://codepen.io/anon/pen/NqazVa , will need some tidy up and reshuffling but the average rate is calculated and displayed correctly.
Check the AngularUI Bootstrap Rating component.

Angular ui-grid dynamically calculate height of the grid

I am using : https://github.com/angular-ui/ui-grid.info/tree/gh-pages/release/3.0.0-RC.18
<div ui-grid="gridOptions" style="height:765px"></div>
When I hard code the value, as shown above, the grid spreads out and everything works as expected.
However, if I do the following...
$scope.gridStyle = 'height:'+numRows*rowHeight+'px' //(765px);
<div ui-grid="gridOptions" style="{{gridStyle}}"></div>
The height is printed in the div and div widens but the content itself widens to only around 340px. The space that is left is blank, so instead of 25 rows I see only 8. I have to scroll down, while there is a whole 400px free in the grid. The ui-grid-viewport and ui-grid-canvas are both not using this space...
Why can't the ui-grid-viewport use that space?
I use ui-grid - v3.0.0-rc.20 because a scrolling issue is fixed when you go full height of container. Use the ui.grid.autoResize module will dynamically auto resize the grid to fit your data. To calculate the height of your grid use the function below. The ui-if is optional to wait until your data is set before rendering.
angular.module('app',['ui.grid','ui.grid.autoResize']).controller('AppController', ['uiGridConstants', function(uiGridConstants) {
...
$scope.gridData = {
rowHeight: 30, // set row height, this is default size
...
};
...
$scope.getTableHeight = function() {
var rowHeight = 30; // your row height
var headerHeight = 30; // your header height
return {
height: ($scope.gridData.data.length * rowHeight + headerHeight) + "px"
};
};
...
<div ui-if="gridData.data.length>0" id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize ng-style="getTableHeight()"></div>
A simpler approach is set use css combined with setting the minRowsToShow and virtualizationThreshold value dynamically.
In stylesheet:
.ui-grid, .ui-grid-viewport {
height: auto !important;
}
In code, call the below function every time you change your data in gridOptions. maxRowToShow is the value you pre-defined, for my use case, I set it to 25.
ES5:
setMinRowsToShow(){
//if data length is smaller, we shrink. otherwise we can do pagination.
$scope.gridOptions.minRowsToShow = Math.min($scope.gridOptions.data.length, $scope.maxRowToShow);
$scope.gridOptions.virtualizationThreshold = $scope.gridOptions.minRowsToShow ;
}
.ui-grid, .ui-grid-viewport,.ui-grid-contents-wrapper, .ui-grid-canvas {
height: auto !important;
}
UPDATE:
The HTML was requested so I've pasted it below.
<div ui-grid="gridOptions" class="my-grid"></div>
ORIGINAL:
We were able to adequately solve this problem by using responsive CSS (#media) that sets the height and width based on screen real estate. Something like (and clearly you can add more based on your needs):
#media (min-width: 1024px) {
.my-grid {
width: 772px;
}
}
#media (min-width: 1280px) {
.my-grid {
width: 972px;
}
}
#media (min-height: 768px) {
.my-grid {
height: 480px;
}
}
#media (min-height: 900px) {
.my-grid {
height: 615px;
}
}
The best part about this solution is that we need no resize event handling to monitor for grid size changes. It just works.
I like Tony approach. It works, but I decided to implement in different way. Here my comments:
1) I did some tests and when using ng-style, Angular evaluates ng-style content, I mean getTableHeight() function more than once. I put a breakpoint into getTableHeight() function to analyze this.
By the way, ui-if was removed. Now you have ng-if build-in.
2) I prefer to write a service like this:
angular.module('angularStart.services').factory('uiGridService', function ($http, $rootScope) {
var factory = {};
factory.getGridHeight = function(gridOptions) {
var length = gridOptions.data.length;
var rowHeight = 30; // your row height
var headerHeight = 40; // your header height
var filterHeight = 40; // your filter height
return length * rowHeight + headerHeight + filterHeight + "px";
}
factory.removeUnit = function(value, unit) {
return value.replace(unit, '');
}
return factory;
});
And then in the controller write the following:
angular.module('app',['ui.grid']).controller('AppController', ['uiGridConstants', function(uiGridConstants) {
...
// Execute this when you have $scope.gridData loaded...
$scope.gridHeight = uiGridService.getGridHeight($scope.gridData);
And at the HTML file:
<div id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize style="height: {{gridHeight}}"></div>
When angular applies the style, it only has to look in the $scope.gridHeight variable and not to evaluate a complete function.
3) If you want to calculate dynamically the height of an expandable grid, it is more complicated. In this case, you can set expandableRowHeight property. This fixes the reserved height for each subgrid.
$scope.gridData = {
enableSorting: true,
multiSelect: false,
enableRowSelection: true,
showFooter: false,
enableFiltering: true,
enableSelectAll: false,
enableRowHeaderSelection: false,
enableGridMenu: true,
noUnselect: true,
expandableRowTemplate: 'subGrid.html',
expandableRowHeight: 380, // 10 rows * 30px + 40px (header) + 40px (filters)
onRegisterApi: function(gridApi) {
gridApi.expandable.on.rowExpandedStateChanged($scope, function(row){
var height = parseInt(uiGridService.removeUnit($scope.jdeNewUserConflictsGridHeight,'px'));
var changedRowHeight = parseInt(uiGridService.getGridHeight(row.entity.subGridNewUserConflictsGrid, true));
if (row.isExpanded)
{
height += changedRowHeight;
}
else
{
height -= changedRowHeight;
}
$scope.jdeNewUserConflictsGridHeight = height + 'px';
});
},
columnDefs : [
{ field: 'GridField1', name: 'GridField1', enableFiltering: true }
]
}
tony's approach does work for me but when do a console.log, the function getTableHeight get called too many time(sort, menu click...)
I modify it so the height is recalculated only when i add/remove rows. Note: tableData is the array of rows
$scope.getTableHeight = function() {
var rowHeight = 30; // your row height
var headerHeight = 30; // your header height
return {
height: ($scope.gridData.data.length * rowHeight + headerHeight) + "px"
};
};
$scope.$watchCollection('tableData', function (newValue, oldValue) {
angular.element(element[0].querySelector('.grid')).css($scope.getTableHeight());
});
Html
<div id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize"></div>
I am late to the game but I found a nice solution. I created a custom attribute directive all you need to do is pass in the gridApi and it will automatically calculate the height. It also subscribes to the pagination change event so if the user changes page size it will resize.
class UIGridAutoResize implements ng.IDirective {
link: (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => void;
scope: { gridApi: "=" };
restrict = "A";
private previousValue: string;
private isValid: boolean = true;
private watch: any;
constructor($timeout: ng.ITimeoutService) {
UIGridAutoResize.prototype.link = (scope: ng.IScope, element: ng.IAugmentedJQuery, attrs: ng.IAttributes) => {
const gridOptions = scope.$eval(attrs.uiGrid) as any;
const gridApi = scope.$eval(attrs.gridResize) as any;
gridApi.core.on.rowsRendered(scope, () => {
$timeout(() => {
this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
}, 100);
});
gridApi.core.on.filterChanged(scope, () => {
this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
});
if (attrs.uiGridPagination === "") {
gridApi.pagination.on.paginationChanged(null, () => {
this.autoSizeGrid(element, attrs, gridOptions, gridApi, true);
});
}
angular.element(window).resize(() => {
$timeout(() => {
this.autoSizeGrid(element, attrs, gridOptions, gridApi, false);
}, 100);
});
};
}
static Factory(): ng.IDirectiveFactory {
const directive = ($timeout: ng.ITimeoutService) => {
return new UIGridAutoResize($timeout);
};
directive["$inject"] = ["$timeout"];
return directive;
}
private autoSizeGrid(element: ng.IAugmentedJQuery, attrs: ng.IAttributes, gridOptions: any, gridApi: any, isPaginationChanged: boolean) {
gridApi.core.handleWindowResize();
// Clear empty grid message
angular.element(element.parent()).find("#emptyGridMessage").remove();
element.find(".ui-grid-viewport").css("display", "");
if (attrs.hidePageSize === "") {
element.find(".ui-grid-pager-row-count-picker").css("display", "none");
}
let rowCount = gridApi.core.getVisibleRows().length;
const headerElements = element.find(".ui-grid-header");
let headerHeight = 2;
if (headerElements.length > 1) { // If we have more than one header element the grid is using grouping
const headerElement = angular.element(headerElements[1]);
headerHeight += headerElement.height();
} else {
headerHeight += headerElements.height();
}
if (attrs.uiGridPagination === "") {
if (rowCount < 1) {
gridOptions.enablePagination = false;
gridOptions.enablePaginationControls = false;
element.css("height", (rowCount * 30) + headerHeight - 2);
element.find(".ui-grid-viewport").css("display", "none");
angular.element("<div id='emptyGridMessage' style='font-size: 1em; width: 100%; background-color: white; border: 1px solid #d4d4d4; padding: 7px 12px; color: #707070;'><span style='opacity: 0.95;'>There are no records.</span></div>").insertAfter(element);
} else if (gridApi.core.getVisibleRows().length < gridOptions.paginationPageSize && !isPaginationChanged) {
gridOptions.enablePagination = false;
gridOptions.enablePaginationControls = false;
element.css("height", (rowCount * 30) + headerHeight);
} else {
gridOptions.enablePagination = true;
gridOptions.enablePaginationControls = true;
element.css("height", (rowCount * 30) + headerHeight);
}
} else {
if (rowCount < 1) {
element.css("height", (rowCount * 30) + headerHeight - 2);
element.find(".ui-grid-viewport").css("display", "none");
angular.element("<div id='emptyGridMessage' style='font-size: 1em; width: 100%; background-color: white; border: 1px solid #d4d4d4; padding: 7px 12px; color: #707070;'><span style='opacity: 0.95;'>There are no records.</span></div>").insertAfter(element);
} else {
element.css("height", (rowCount * 30) + headerHeight);
}
}
// Add extra margin to prevent scroll bar and pager from overlapping content underneath
const pagerHeight = element.find(".ui-grid-pager-panel").height();
if (rowCount > 0) {
if (pagerHeight > 0)
element.css("margin-bottom", pagerHeight);
else
element.css("margin-bottom", 10);
} else {
if (pagerHeight > 0)
angular.element(element.parent()).find("#emptyGridMessage").css("margin-bottom", pagerHeight);
else
angular.element(element.parent()).find("#emptyGridMessage").css("margin-bottom", 10);
}
if (rowCount > gridOptions.paginationPageSize) // Sometimes paging shows all rows this fixes that
gridApi.core.refresh();
}
}
<div ui-grid="vm.gridOptions" grid-resize="vm.gridApi" ui-grid-resize-columns ui-grid-pagination></div>
following #tony's approach, changed the getTableHeight() function to
<div id="grid1" ui-grid="$ctrl.gridOptions" class="grid" ui-grid-auto-resize style="{{$ctrl.getTableHeight()}}"></div>
getTableHeight() {
var offsetValue = 365;
return "height: " + parseInt(window.innerHeight - offsetValue ) + "px!important";
}
the grid would have a dynamic height with regards to window height as well.
