I have an angular-ui ui-scroll directive (1.3.0) living in a div that is hidden by default with an ng-show. When it is hidden, ui-scroll just keeps loading data from the datasource even though the ui-scroll-viewport's height is set. If the div is shown, it behaves correctly. So, for now my div is 1px wide :/
I'm sure I can solve this with an ng-if to dynamically add this to the DOM. However, I wanted the div to hide/show responsively - so driven off of css.
Any suggestions on how to have ui-scroll only load 1 page from the buffer when hidden? thank you.
You can try to manage it through the datasource implementation:
$scope.datasource.get = function(index, count, success) {
// prevent data getting while ui-scroll is invisible
if (!$scope.isScrollerVisible) {
return; // or let him request for 1 pack and prevent others, any logic
}
// get required data and pass it into success callback
var result = [];
for (var i = index; i <= index + count - 1; i++) {
result.push({text: "item #" + i});
}
success(result);
}
Also you probably need to initiate scroll reloading once (adapter doc):
$scope.$watch('isScrollerVisible', function(value) {
if(value) {
$scope.datasourceAdapter.reload()
}
});

I have this code
var input = element.find('input').eq(0);
scope.focus = function() {
if (!input.length) return;
input[0].focus();
input[0].select();
var divWrapper = input.parent('.tags')[0];
divWrapper.scrollLeft = divWrapper.scrollWidth;
console.log(divWrapper.scrollWidth);
console.log(divWrapper.scrollLeft);
};
This is inside a directive fnLink and focus is called when ui is changed this because use overflow: hidden and input disapear when many items on left... so I need to scroll to far right and keep input visible.
The
divWrapper.scrollLeft = divWrapper.scrollWidth;
works fine on chrome dev tools but when focus is called don't update the scrollLeft attribute.
I am trying to hide extjs date-field on clicking anywhere on DOM except date-field. while clicking anywhere in dom bodyClick function get called.On basis of page co-ordinates element object get retrieved and then this element object get compared with date-field object.This works fine but problem comes whenever i am clicking on date-picker again "date-field" get hide.
sample code -
bodyClick: function(e){
var me = this, elem, t;
var flag =true;
elem = me.getEl();
for(t = Ext.dom.Element.fromPoint(e.getX(), e.getY()); t && t != null;){
if (Ext.fly(elem ).contains(t)){
flag =false;
}
}
if(flag ){
me.hide();
}
}
Any Suggestions for hiding datefield while clicking anywhere in DOM (extJs).
You can try this in afterRender of the panel or container in which your component is in.
this.mon(Ext.getBody().getEl(), 'click', this.yourFunction, this);
yourFunction:function(e){
var comp = Ext.ComponentQuery.query('datepicker')[0];//Get your datepicker component
if (Ext.fly(e.getTarget()) != comp) { //get the target using Ext.fly
comp.hide(); //Hide the component if the target is not the datepicker
}
}
Hope this helps you.
How do I reset my ExtJS filters in my grids. More specifically, how do I get the header to honour the changes to the filtering.
ie. This works fine :
grid.store.clearFilter();
But the header rendering is all wrong. I need to get into all the menu objects and unselect the checkboxes.
I am getting pretty lost. I am pretty sure this gives me the filterItems :
var filterItems = grid.filters.filters.items;
And from each of these filter items, i can get to menu items like so :
var menuItems = filter.menu.items;
But that's as far as I can get. I am expecting some kind of checkbox object inside menu items, and then I can uncheck that checkbox, and hopefully the header rendering will then change.
UPDATE :
I now have this code. The grid store has its filter cleared. Next I get the filterItems from grid.filters.filters.items and iterate over them. Then I call a function on each of the menu items.
grid.store.clearFilter();
var filterItems = grid.filters.filters.items;
for (var i = 0; i<filterItems.length; i++){
var filter = filterItems[i];
filter.menu.items.each(function(checkbox) {
if (checkbox.setChecked)
checkbox.setChecked(false, true);
});
}
The checkboxes do get called, but still nothing is happening :(
Try this code:
grid.filters.clearFilters();
This should take care of both the grid and its underlying store.
When you do
grid.store.clearFilter();
it can only clear the filters on the store but the grid's view doesn't get updated with that call. Hence to handle it automatically for both the grid's view as well as the grid's store, just use
grid.filters.clearFilters();
Hope it helps!
Cheers!
Your update help me but you forget the case where you have input text instead of checkbox.
So this is my addition of your solution:
grid.filters.clearFilters();
var filterItems = grid.filters.filters.items;
for (var i = 0; i<filterItems.length; i++){
var filter = filterItems[i];
filter.menu.items.each(function(element) {
if (element.setChecked) {
element.setChecked(false, true);
}
if(typeof element.getValue !== "undefined" && element.getValue() !== "") {
element.setValue("");
}
});
}
When you use grid wiht gridfilters plugin
and inovoke
grid.filters.clearFilters();
it reset applyed filters, but it don't clean value in textfield inside menu.
For clean textfield text you can try this:
grid.filters.clearFilters();
const plugin = grid.getPlugin('gridfilters');
let activeFilter;
if('activeFilterMenuItem' in plugin) {
activeFilter = plugin.activeFilterMenuItem.activeFilter
}
if (activeFilter && activeFilter.type === "string") {
activeFilter.setValue("");
}
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.
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"));
}
}
});
});
