I want to trigger ng-click of an element at runtime like:
_ele.click();
OR
_ele.trigger('click', function());
How can this be done?
The syntax is the following:
function clickOnUpload() {
$timeout(function() {
angular.element('#myselector').triggerHandler('click');
});
};
// Using Angular Extend
angular.extend($scope, {
clickOnUpload: clickOnUpload
});
// OR Using scope directly
$scope.clickOnUpload = clickOnUpload;
More info on Angular Extend way here.
If you are using old versions of angular, you should use trigger instead of triggerHandler.
If you need to apply stop propagation you can use this method as follows:
<a id="myselector" ng-click="clickOnUpload(); $event.stopPropagation();">
Something
</a>
angular.element(domElement).triggerHandler('click');
EDIT:
It appears that you have to break out of the current $apply() cycle. One way to do this is using $timeout():
$timeout(function() {
angular.element(domElement).triggerHandler('click');
}, 0);
See fiddle: http://jsfiddle.net/t34z7/
This following solution works for me :
angular.element(document.querySelector('#myselector')).click();
instead of :
angular.element('#myselector').triggerHandler('click');
Just in case everybody see's it, I added additional duplicating answer with an important line which will not break event propagation
$scope.clickOnUpload = function ($event) {
$event.stopPropagation(); // <-- this is important
$timeout(function() {
angular.element(domElement).trigger('click');
}, 0);
};
Using plain old JavaScript worked for me:
document.querySelector('#elementName').click();
The best solution is to use:
domElement.click()
Because the angularjs triggerHandler(angular.element(domElement).triggerHandler('click')) click events does not bubble up in the DOM hierarchy, but the one above does - just like a normal mouse click.
https://docs.angularjs.org/api/ng/function/angular.element
http://api.jquery.com/triggerhandler/
https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement/click
You can do like
$timeout(function() {
angular.element('#btn2').triggerHandler('click');
});
This code will not work (throw an error when clicked):
$timeout(function() {
angular.element('#btn2').triggerHandler('click');
});
You need to use the querySelector as follows:
$timeout(function() {
angular.element(document.querySelector('#btn2')).triggerHandler('click');
});
Simple sample:
HTML
<div id='player'>
<div id="my-button" ng-click="someFuntion()">Someone</div>
</div>
JavaScript
$timeout(function() {
angular.element('#my-button').triggerHandler('click');
}, 0);
What this does is look for the button's id and perform a click action. Voila.
Source: https://techiedan.com/angularjs-how-to-trigger-click/
Include following line in your method there you want to trigger click event
angular.element('#btn_you_want_to_click_progmaticallt').triggerHandler('click');
});

I'm having a hard time understand how to simulate a mouse click using JQuery. Can someone please inform me as to what i'm doing wrong.
HTML:
<a id="bar" href="http://stackoverflow.com" target="_blank">Don't click me!</a>
<span id="foo">Click me!</span>
jQuery:
jQuery('#foo').on('click', function(){
jQuery('#bar').trigger('click');
});
Demo: FIDDLE
when I click on button #foo I want to simulate a click on #bar however when I attempt this, nothing happens. I also tried jQuery(document).ready(function(){...}) but without success.
You need to use jQuery('#bar')[0].click(); to simulate a mouse click on the actual DOM element (not the jQuery object), instead of using the .trigger() jQuery method.
Note: DOM Level 2 .click() doesn't work on some elements in Safari. You will need to use a workaround.
http://api.jquery.com/click/
You just need to put a small timeout event before doing .click()
like this :
setTimeout(function(){ $('#btn').click()}, 100);
This is JQuery behavior. I'm not sure why it works this way, it only triggers the onClick function on the link.
Try:
jQuery(document).ready(function() {
jQuery('#foo').on('click', function() {
jQuery('#bar')[0].click();
});
});
See my demo: http://jsfiddle.net/8AVau/1/
jQuery(document).ready(function(){
jQuery('#foo').on('click', function(){
jQuery('#bar').simulateClick('click');
});
});
jQuery.fn.simulateClick = function() {
return this.each(function() {
if('createEvent' in document) {
var doc = this.ownerDocument,
evt = doc.createEvent('MouseEvents');
evt.initMouseEvent('click', true, true, doc.defaultView, 1, 0, 0, 0, 0, false, false, false, false, 0, null);
this.dispatchEvent(evt);
} else {
this.click(); // IE Boss!
}
});
}
May be useful:
The code that calls the Trigger should go after the event is called.
For example, I have some code that I want to be executed when #expense_tickets value is changed, and also, when page is reload
$(function() {
$("#expense_tickets").change(function() {
// code that I want to be executed when #expense_tickets value is changed, and also, when page is reload
});
// now we trigger the change event
$("#expense_tickets").trigger("change");
})
jQuery's .trigger('click'); will only cause an event to trigger on this event, it will not trigger the default browser action as well.
You can simulate the same functionality with the following JavaScript:
jQuery('#foo').on('click', function(){
var bar = jQuery('#bar');
var href = bar.attr('href');
if(bar.attr("target") === "_blank")
{
window.open(href);
}else{
window.location = href;
}
});
Try this that works for me:
$('#bar').mousedown();
Technically not an answer to this, but a good use of the accepted answer (https://stackoverflow.com/a/20928975/82028) to create next and prev buttons for the tabs on jQuery ACF fields:
$('.next').click(function () {
$('#primary li.active').next().find('.acf-tab-button')[0].click();
});
$('.prev').click(function () {
$('#primary li.active').prev().find('.acf-tab-button')[0].click();
});
I have tried top two answers, it doesn't worked for me until I removed "display:none" from my file input elements.
Then I reverted back to .trigger() it also worked at safari for windows.
So conclusion, Don't use display:none; to hide your file input , you may use opacity:0 instead.
Just use this:
$(function() {
$('#watchButton').trigger('click');
});
You can't simulate a click event with javascript.
jQuery .trigger() function only fires an event named "click" on the element, which you can capture with .on() jQuery method.
I know the click action can be triggered by assigning ontap a specific function like so:
{
kind: "moon.Button",name :"search_button",
content : "Search" , ontap : "searchAction", classes: "menu-button-style"
}
.
.
.
searchAction : function(){ //do some stuff on click}
I've tried
$('#id_of_my_button').click();
$('#id_of_my_button').trigger('click');
and none of those seem to work.
simplified jsFiddle
Any ideas
Why trigger the click with jquery? You can force an event with Enyo, as well:
this.$.someButton.bubble("ontap", {...});
Here, try this:
http://jsfiddle.net/Djspaceg/2AWb5/6/
Enyo has a global handle (enyo) you can use if you need to access any part of its structure. It's not recommended for use from within our app, since it breaks encapsulation, but since you're already outside enyo (by using jQuery or plain JavaScript) I don't see as much harm.
function TapThat() {
// 'enyo' is the global namespace.
// The '$' refers to the children of the object/kind.
enyo.$.tappyButton.tapAction();
}
Using the native click function of elements seems to work in your case, like this:
window.onload = function (){
document.getElementById('tappyButton').click();
};
Demo
Your problem in the fiddle is that you haven't included jQuery. Also, probably that you don't wait for the element to be added to the DOM before binding a click listener to it.
Demo with jQuery
I have the following jQuery code:
$('#temp_modals').on('mouseleave','*[data-username]',function() {
///my logic
});
However I need to to have the mouseleave event on the the parent div of *[data-username].
As this element is added dynamically to the webpage I cannot use a normal selector and need to use the $.on.
In short I want to achieve that code like this runs.
$('#temp_modals').on('mouseleave','*[data-username]'.parent(),function() {
///my logic
});
How can I do that?
Try
$('#temp_modals').on('mouseleave','*:has(> [data-username])',function(event) {
///my logic
// this should get you the parent.
$(event.target).parent();
});
Demo: Fiddle
According to the spec this should work
http://api.jquery.com/parent-selector/
$('#temp_modals').on('mouseleave','*[data-username]:parent',function() {
///my logic
});
EDIT : Indeed this won't work, thanks for pointing it out, :parent doesn't do what i was expected. This will work :
$('#temp_modals').on('mouseleave',$('*[data-username]').parent(),function() {
console.log(this)
});
The problem is that I have some dynamically created sets of input tags and I also have a function that is meant to trigger any time an input value is changed.
$('input').on('change', function() {
// Does some stuff and logs the event to the console
});
However the .on('change') is not triggering for any dynamically created inputs, only for items that were present when the page was loaded. Unfortunately this leaves me in a bit of a bind as .on is meant to be the replacement for .live() and .delegate() all of which are wrappers for .bind() :/
Has anyone else had this problem or know of a solution?
You should provide a selector to the on function:
$(document).on('change', 'input', function() {
// Does some stuff and logs the event to the console
});
In that case, it will work as you expected. Also, it is better to specify some element instead of document.
Read this article for better understanding: http://elijahmanor.com/differences-between-jquery-bind-vs-live-vs-delegate-vs-on/
You can use any one of several approaches:
$("#Input_Id").change(function(){ // 1st way
// do your code here
// Use this when your element is already rendered
});
$("#Input_Id").on('change', function(){ // 2nd way
// do your code here
// This will specifically call onChange of your element
});
$("body").on('change', '#Input_Id', function(){ // 3rd way
// do your code here
// It will filter the element "Input_Id" from the "body" and apply "onChange effect" on it
});
Use this
$('body').on('change', '#id', function() {
// Action goes here.
});
Just to clarify some potential confusion.
This only works when an element is present on DOM load:
$("#target").change(function(){
//does some stuff;
});
When an element is dynamically loaded in later you can use:
$(".parent-element").on('change', '#target', function(){
//does some stuff;
});
$("#id").change(function(){
//does some stuff;
});
you can use:
$('body').ready(function(){
$(document).on('change', '#elemID', function(){
// do something
});
});
It works with me.
You can use 'input' event, that occurs when an element gets user input.
$(document).on('input', '#input_id', function() {
// this will fire all possible change actions
});
documentation from w3
$(document).on('change', '#id', aFunc);
function aFunc() {
// code here...
}
I've seen a couple of questions in regards to bootstrap modals, but none exactly like this, so I'll go ahead.
I have a modal that I call onclick like so...
$(".modal-link").click(function(event){
$("#modal-content").modal('show');
});
This works fine, but when I show the modal I want to focus on the first input element... In may case the first input element has an id of #photo_name.
So I tried
$(".modal-link").click(function(event){
$("#modal-content").modal('show');
$("input#photo_name").focus();
});
But this was to no avail. Lastly, I tried binding to the 'show' event but even so, the input won't focus. Lastly just for testing, as I had a suspiscion this is about the js loading order, I put in a setTimeout just to see if I delay a second, will the focus work, and yes, it works! But this method is obviously crap. Is there some way to have the same effect as below without using a setTimeout?
$("#modal-content").on('show', function(event){
window.setTimeout(function(){
$(event.currentTarget).find('input#photo_name').first().focus()
}, 0500);
});
Try this
Here is the old DEMO:
EDIT:
(Here is a working DEMO with Bootstrap 3 and jQuery 1.8.3)
$(document).ready(function() {
$('#modal-content').modal('show');
$('#modal-content').on('shown', function() {
$("#txtname").focus();
})
});
Starting bootstrap 3 need to use shown.bs.modal event:
$('#modal-content').on('shown.bs.modal', function() {
$("#txtname").focus();
})
Just wanted to say that Bootstrap 3 handles this a bit differently. The event name is "shown.bs.modal".
$('#themodal').on('shown.bs.modal', function () {
$("#txtname").focus();
});
or put the focus on the first visible input like this:
.modal('show').on('shown.bs.modal', function ()
{
$('input:visible:first').focus();
})
http://getbootstrap.com/javascript/#modals
I am using this in my layout to capture all modals and focus on the first input
$('.modal').on('shown', function() {
$(this).find('input').focus();
});
I had the same problem with bootstrap 3, focus when i click the link, but not when trigger the event with javascript.
The solution:
$('#myModal').on('shown.bs.modal', function () {
setTimeout(function(){
$('#inputId').focus();
}, 100);
});
Probably it´s something about the animation!
I had problem to catch "shown.bs.modal" event.. And this is my solution which works perfect..
Instead simple on():
$('#modal').on 'shown.bs.modal', ->
Use on() with delegated element:
$('body').on 'shown.bs.modal', '#modal', ->
Seems it is because modal animation is enabled (fade in class of the dialog), after calling .modal('show'), the dialog is not immediately visible, so it can't get focus at this time.
I can think of two ways to solve this problem:
Remove fade from class, so the dialog is immediately visible after calling .modal('show'). You can see http://codebins.com/bin/4ldqp7x/4 for demo. (Sorry #keyur, I mistakenly edited and saved as new version of your example)
Call focus() in shown event like what #keyur wrote.
I've created a dynamic way to call each event automatically. It perfect to focus a field, because it call the event just once, removing it after use.
function modalEvents() {
var modal = $('#modal');
var events = ['show', 'shown', 'hide', 'hidden'];
$(events).each(function (index, event) {
modal.on(event + '.bs.modal', function (e) {
var callback = modal.data(event + '-callback');
if (typeof callback != 'undefined') {
callback.call();
modal.removeData(event + '-callback');
}
});
});
}
You just need to call modalEvents() on document ready.
Use:
$('#modal').data('show-callback', function() {
$("input#photo_name").focus();
});
So, you can use the same modal to load what you want without worry about remove events every time.
I had the same problem with the bootstrap 3 and solved like this:
$('#myModal').on('shown.bs.modal', function (e) {
$(this).find('input[type=text]:visible:first').focus();
})
$('#myModal').modal('show').trigger('shown');
Bootstrap has added a loaded event.
https://getbootstrap.com/docs/3.3/javascript/#modals
capture the 'loaded.bs.modal' event on the modal
$('#mymodal').on('loaded.bs.modal', function(e) {
// do cool stuff here all day… no need to change bootstrap
})
Bootstrap modal show event
$('#modal-content').on('show.bs.modal', function() {
$("#txtname").focus();
})
A little cleaner and more modular solution might be:
$(document).ready(function(){
$('.modal').success(function() {
$('input:text:visible:first').focus();
});
});
Or using your ID as an example instead:
$(document).ready(function(){
$('#modal-content').modal('show').success(function() {
$('input:text:visible:first').focus();
});
});
Hope that helps..
