How to Trigger Click on Page Load

How to trigger click on page load?

The click handler that you are trying to trigger is most likely also attached via $(document).ready(). What is probably happening is that you are triggering the event before the handler is attached. The solution is to use setTimeout:

$("document").ready(function() {
    setTimeout(function() {
        $("ul.galleria li:first-child img").trigger('click');
    },10);
});

A delay of 10ms will cause the function to run immediately after all the $(document).ready() handlers have been called.

OR you check if the element is ready:

$("document").ready(function() {
  $("ul.galleria li:first-child img").ready(function() {
    $(this).click();
  });    
});

can I trigger click event onload

If your goal is to bypass pop-up blockers on page load, triggering the click event synthetically probably won't work. Browsers are smart enough to know when a click is user-generated vs. when you've called the click function on the DOM element (on those browsers were that even works). Examples: http://jsbin.com/avibi3/3, http://jsbin.com/avibi3/4

Using jQuery's trigger mechanism certainly won't do it, because it doesn't really trigger a click event at all; it just fires the handlers that jQuery hooked up (edit: and, apparently, ones defined via an onclick attribute — see Sukhi's answer — but not ones attached via addEventListener). If that's what you want to do, Sukhi's answer shows you how, although I always say: If you want code to be run from two different places, put it in a function, and call that function from two different places (rather than putting it in a click handler and then simulating a click just to run the code). There are valid use cases for trigger (mostly relating to integrating with third-party scripts), but for running your own code from two different places, it's a symptom of a design problem.

Trigger click after load page

I give you example here

$(document).ready(function(){
   $("#reset").click();
})

the code above should work.

Trigger click function on load

Yes.

$(document).ready(function(){ // on document ready
    $(".results .view-rooms").click(); // click the element
})

Trigger onClick(); on page load

use .click() or .trigger('click') in dom ready with selector:

$(".rope").click();
//or
$(".rope").trigger('click');

Trigger button click event programmatically using JavaScript or jQuery on page load in Internet Explorer

You can try like this:

$(document).ready(function(){
    $('#btnFilter').trigger('click');
});

$(document).on('click','#btnFilter',function(e){
    btnFilter(e);
});

function btnFilter(e)
{
    element = e.currentTarget.parentElement;
}

Trigger Event Click upon page load

I see that you have used jQuery on the page. So you can simply do this :

 $(function(){
     angular.element("#one").trigger("click"); 
 });

A complete jQuery solution would be :

 $(function(){
    $("#one").click(); 
 });

A complete angular solution would be (like others mentioned) :

angular.element(document).ready(function() {
    angular.element("#one").trigger("click"); 
});

You are triggering the code to click when the document is not completely ready/rendered so you need to wait till the entire document(or in this case, your checkbox) is loaded and only then you can perform actions on your elements.
