Value is not applied to Ng-Class on window resize - angularjs

I have the following controller:
function PlansController($scope) {
var vm = this;
vm.plan = null;
vm.show = function (plan) {
vm.plan = plan;
}
$scope.$on("match", function (event, mq) {
if (mq === "mobile") {
vm.plan = "free";
console.log(vm.plan);
}
});
})();
The $scope.$on match fires when the media query "screen and (max-width: 31.9375em)" matches. Then I have the following:
<table class="plans" data-ng-class="vm.plan">
When I load the page with a width that matches the media query I can see that vm.plan class is applied to the table ...
The problem is when open the page in a large width. When I resize it to mobil I see in the console that the vm.plan becomes "free", so the Match condition fires and vm.plan is defined, but the CSS class is not applied to the table.
UPDATE
I just added an example in https://jsfiddle.net/g3wzayp3/11/
Just increase the HTML preview pane and you will see on console the value "true" when the width matches the media query ... But the class is not applied to the text ...
Any idea why?

Are you trying to apply the class called "free" on resize? If yes, this is not the way to do it. ng-class is used like {free: vm.plan} where vm.plan becomes true or false
Example:
<div ng-class="{free: should_apply}">Hello</div>
where free is the class that you want to apply, should_apply is a variable that evaluates to true or false
Here's a fiddle example:
https://jsfiddle.net/a7u1m3n6/
UPDATE:
You need to call $scope.$apply(); in the $on method. Here's the fiddle - https://jsfiddle.net/g3wzayp3/12/

Unable to have an ol3 map in each angular module

I'm using openlayers3 (ol3) and angular 1.5.6 on IE Edge.
I have two modules. Each has their own controller and component. Each controller wants to have a map in the view. One view is for interactively querying data off its map. The other view is for displaying interactive query results.
Under the hood, I provide a MapFactory which returns an instance of a object, containing the said openlayers map.
PROBLEM: The one displays while the other does not.
Here's a sample of my code (some details are left out for simplicity. For example the dependency injection checks. All of this code is being called as expected.):
Module A definition
angular.module('ModuleA').controller('ModuleAController',ModuleAController);
ModuleAController.$inject = ['MapFactory'];
function ModuleAController(MapFactory){
var vm = this;
var vm.map = MapFactory.getMapInstance({
id:'module-A-map',
otherOption:true
});
}
In ModuleA's view:
<div id='module-A-map' class="map-classes"></div>
Module B definition
angular.module('ModuleB').controller('ModuleBController',ModuleBController);
ModuleBController.$inject = ['MapFactory'];
function ModuleBController(MapFactory){
var vm = this;
var vm.map = MapFactory.getMapInstance({
id:'module-B-map',
otherOption:true
});
}
In ModuleB's view:
<div id='module-B-map' class="map-classes"></div>
MapFactory's definition:
angular.module('common').factory('MapFactory',MapFactory);
MapFactory.$inject = [];
function MapFactory(){
var factory = {
getMapInstance : getMapInstance
};
return factory;
function getMapInstance(options){
return new _MapConstructor(options);
}
function _MapConstructor(options){
var _map = new ol.Map({
target : options.id,
logo : false,
view : new ol.View({...}),
layers : [some,layers,here]
});
return {
publicMethod : publicMethod
};
function publicMethod(){...}
function privateMethod(){...}
... other stuff ...
}
}
Please, let me know if any clarification is needed to answer the question.
MORE:
This issue: https://github.com/openlayers/ol3/issues/4601 might be part of the problem. I am using collapsable DIVs with bootstrap. The ModuleA is in the default displayed one, while ModuleB is hidden at first. More to come.
I wrote this up as an OL3 issue as well: https://github.com/openlayers/ol3/issues/5789
ABSTRACT ANSWER:
http://getbootstrap.com/javascript/#collapse-events
I need to add a _map.updateSize() on a show.bs.collapse or shown.bs.collapse event. Now, I need to figure out how to do that in Angular, and post it (unless somebody gets to it first).
Ah, this is in Bootstrap's collapse class. So, let's back up to the Module-B view. Each of my Module's is a panel within a Bootstrap panel accordian. The ModuleA map that displays is the default open panel (the one that has the in class). The ModuleB map is not open by default, and thus, OL3 gives the canvas a display:none in the map's div's style.
<div id="module-B-collapse" class="panel-collapse collapse" >
<div id='module-B-map' class="map-classes"></div>
....
</div>
In my ModuleBController, I simply added:
angular.element('#module-B-collapse').on('shown.bs.collapse',function(){
_map.updateSize();
});

How to get the value of selected row directly in HTML using ag-grid

i try to get the the value of number row selected, and print it in HTML using Angularjs, but no issue,
i have the count only when i clic in the grid column header.
The value of " selectedRowsCounter " is 0 in html, when i dosn't clic in the grid header
my code is like
var activeButtons = function() {
var countRowsSelected = $scope.gridOptions.api.getSelectedRows().length;
$scope.selectedRowsCounter = countRowsSelected;
console.log($scope.selectedRowsCounter);
$rootScope.count.selectedRows = countRowsSelected;
};
$scope.gridOptions = {
rowData: null,
angularCompileRows: true,
onSelectionChanged: activeButtons,
}
there is a screenshot
i have open the same subject here
https://github.com/ceolter/ag-grid/issues/1023
i have added this line to activeButtons function and it work fine
$scope.gridOptions.api.refreshView();
i dont knew if there is a good solution, but that work for now
The problem seems to be with Angular being unaware of the $scope property change because ag-grid does not tell Angular that it has modified something in the $scope. Although it is difficult to tell if you don't show your view.
You can use onSelectionChanged the way you are using it to know how many rows have been selected, but you need to tell Angular that something has changed in its $scope by applying it.
Something like this:
var activeButtons = function() {
var countRowsSelected = $scope.gridOptions.api.getSelectedRows().length;
$scope.selectedRowsCounter = countRowsSelected;
console.log($scope.selectedRowsCounter);
$rootScope.count.selectedRows = countRowsSelected;
window.setTimeout(function() {
this.$scope.$apply();
});
};
That way you can apply the $scope and the html view will reflect the changes.

AngularJS animate dynamic margin

I have an element that appears when the user clicks a button elsewhere on the screen. The element appears to come out of the top of the screen. The element by default needs to be tucked out of view above the screen, so I will have a margin-top style that is based on the height of the element (and will be a negative value). This cannot be hardcoded in css because the element height may vary. When I click the button, I want the element margin-top to change to 0 and I want a transition animation.
The sample shown on angularJS documentation is for adding a removing a class. This would work fine if I knew the values to be set and could code them in CSS, however I cannot. What is the correct way to solve this?
The code below works for displaying and hiding my element using a margin but there is no animation. How do I trigger an animation here when the margin changes?
https://docs.angularjs.org/guide/animations
Quote Total: {{salesPriceTotal + taxesTotal - tradeInsTotal | currency}}
<div class="totals" ng-style="setTopMargin()">
// totals stuff here.
</div>
$scope.setTopMargin = function() {
return {
marginTop: $scope.marginTop
}
};
$scope.$watch('showTotals', function() {
var margin = $scope.showTotals ? 10 : -160 + $scope.modelTotals.length * -200;
$scope.marginTop = margin.toString() + 'px';
});
I added the following code per a suggested solution, but this code is never hit.
myApp.animation('.totals', function () {
return {
move: function (element, done) {
element.css('opacity', 0);
jQuery(element).animate({
opacity: 1
}, done);
// optional onDone or onCancel callback
// function to handle any post-animation
// cleanup operations
return function (isCancelled) {
if (isCancelled) {
jQuery(element).stop();
}
}
},
}
});
As the documentation explains: "The same approach to animation can be used using JavaScript code (jQuery is used within to perform animations)".
So you basically needs to use animate() from jQuery to do what you want.

ExtJS 4.1: Modal Window seems to return control before submitting the window

I wasn't sure how to describe my question in the question title. But here is my problem:
(a) When I double click on a row in an Ext.grid.Panel, I open a modal window with it's relavant details to update the record.
(b) After I make the needed modifications and close the modal window, I want to return to the Grid with the Grid filtered on a certain code i.e selectedSalesOrderNum.
jobSlotsGrid.on('celldblclick', function(tableview, td, cellIndex, record, tr, rowIndex, e, eOpts){
modalStatus = loadWindow();
jobSlotStore.filterBy(function(rec) {
alert('Filtering data');
return rec.get('salesOrderNum') === selectedSalesOrderNum;
});
});
(c) Below is the function, which creates the model window. It also has the call to method submitCreateJobSlotHandler() which basically saves the changes and reloads the original Grid with all the data. ( Hence the necessity to filter it back with a certain code i.e selectedSalesOrderNum ).
function loadWindow()
{
getAllTabsForEditJobSlot();
var createJobSlotWin = new Ext.Window({
id:'salesOrder-win-jobSlot',
applyTo : 'hello-win',
modal : true,
layout : 'fit',
width : 900,
height : 500,
closeAction :'destroy',
plain : true,
model : true,
stateful : false,
title :'Create Job Slot',
items : [editJobSlotInformationPanel],
buttons : [{
text : 'Save',
handler : function(){
submitCreateJobSlotHandler();
//createJobSlotWin.destroy();
}
},{
text : 'Close',
handler : function(){
createJobSlotWin.destroy();
}
}]
});
createJobSlotWin.show();
}
The Issue:
In the first block of code, as soon as the loadWindow method is called, both a modal window is popped up along with the filterBy code getting executed in parallel and showing up the alerts ( 'Filtering data' ). I then enter the data in the modal and save. So, basically, the filtering is not done after the Save/Close on Modal. The code ( if/else ) is immediately reached after loading the modal window. It is as if, the modal window opens and goes to the next line of code while waiting for the user to perform some action on the modal window later.
Hope I am clear on my question. Could anyone please advice how do I handle this?
EDIT:
The more I think about it now, I guess the loadWindow() method just creates the Modal Window as we just have a new Ext.Window() call and doesn't bother about other user actions inside the modal and returns the control. And hence, executes the subsequent filterBy event immediately. In that case, I want to filter the store after I am reloading the store upon the Save in Modal Window. The save on Modal window has this handler code:
function submitCreateJobSlotHandler () {
alert('Into Submit');
var formPanel = Ext.getCmp('salesOrderJobSlotForm');
formPanel.getForm().submit({
url : 'someUrl',
method : 'POST',
success : function() {
alert('Success');
jobSlotStore.load({
scope : this,
url : 'salesOrderJobSlot/listJSON'
});
jobSlotStore.filterBy(function(rec) {
alert(rec.get('salesOrderNum')+"--"+selectedSalesOrderNum)
return rec.get('salesOrderNum') === selectedSalesOrderNum;
});
},
failure : function() {
alert('PSO save failed!');
}
});
}
But the issue here is, the jobSlotStore.load() though gets called, it holds until the filterBy gets executed. Because, I see the alerts coming up one by one and then after all the alerts are done, the store loads. So, the filterBy gets overriden by the 'late' store load.
Any suggestions to deal with the issue in any of the ways?
The store load is asynchronous, you need to wait til it completes before you can filter the data set on the client:
store.on('load', function() {
store.filter();
}, null, {single: true});
store.load();

Add class to DIV if checkbox is checked onload

I need help with a script to add an "active" class to a div when a hidden checkbox is checked. This all happening within a somewhat complex form that can be saved and later edited. Here's the process:
I have a series of hidden checkboxes that are checked when a visible DIV is clicked. Thanks to a few people, especially Dimitar Christoff from previous posts here, I have a few simple scripts that handle everything:
A person clicks on a div:
<div class="thumb left prodata" data-id="7"> yadda yadda </div>
An active class is added to the div:
$$('.thumb').addEvent('click', function(){
this.toggleClass('tactive');
});
The corresponding checkbox is checked:
document.getElements("a.add_app").addEvents({
click: function(e) {
if (e.target.get("tag") != 'input') {
var checkbox = document.id("field_select_p" + this.get("data-id"));
checkbox.set("checked", !checkbox.get("checked"));
}
}
});
Now, I need a fourth ( and final ) function to complete the project (using mootools or just plain javascript, no jQuery). When the form is loaded after being saved, I need a way to add the active class back to the corresponding div. Basically reverse the process. I AM trying to figure it out myself, and would love to post an idea but anything I've tried is, well, bad. I thought I'd at least get this question posted while I work on it. Thanks in advance!
window.addEvents({
load: function(){
if (checkbox.checked){
document.getElements('.thumb').fireEvent('click');
}
}
});
Example: http://jsfiddle.net/vCH9n/
Okay, in case anyone is interested, here is the final solution. What this does is: Create a click event for a DIV class to toggle an active class onclick, and also correlates each DIV to a checkbox using a data-id="X" that = the checkbox ID. Finally, if the form is reloaded ( in this case the form can be saved and edited later ) the final piece of javascript then sees what checkboxes are checked on page load and triggers the active class for the DIV.
To see it all in action, check it out here: https://www.worklabs.ca/2/add-new/add-new?itemetype=website ( script is currently working on the third tab, CHOOSE STYLE ). You won't be able to save/edit it unless you're a member however, but it works:) You can unhide the checkboxes using firebug and toggle the checkboxes yourself to see.
window.addEvent('domready', function() {
// apply the psuedo event to some elements
$$('.thumb').addEvent('click', function() {
this.toggleClass('tactive');
});
$$('.cbox').addEvent('click', function() {
var checkboxes= $$('.cbox');
for(i=1; i<=checkboxes.length; i++){
if(checkboxes[i-1].checked){
if($('c_'+checkboxes[i-1].id))
$('c_'+checkboxes[i-1].id).set("class", "thumb tactive");
}
else{
if($('c_'+checkboxes[i-1].id))
$('c_'+checkboxes[i-1].id).set("class", "thumb");
}
}
});
// Add the active class to the corresponding div when a checkbox is checked onLoad... basic idea:
var checkboxes= $$('.cbox');
for(i=1; i<=checkboxes.length; i++){
if(checkboxes[i-1].checked){
$('c_field_tmp_'+i).set("class", "thumb tactive");
}
}
document.getElements("div.thumb").addEvents({
click: function(e) {
if (e.target.get("tag") != 'input') {
var checkbox = document.id("field_tmp_" + this.get("data-id"));
checkbox.set("checked", !checkbox.get("checked"));
}
}
});
});
