Trigger click Checkbox After page fully loaded

How I run trigger click after page FULLY loaded
I have a checkbox and want to trigger a click.
my code is simple
jQuery(document).ready(function(){
jQuery('.wcpf-input-checkbox[value="hoodie"]').trigger('click');
});
but it does not work, I tes the script in console after fullu loaded, my script work
I also to try to check if the checkbox ready. it does not work.
jQuery(document).ready(function(){
jQuery('.wcpf-input-checkbox[value="hoodie"]').ready(function(){
jQuery(this).click();
});
});
How do I trigger click to work?

If you attach click action with this method:
$(yourobj).on("click",function() {...});
then you can change it to:
$(document).on("click", 'yourobj', function(event) {...});
But I don't know, you haven't posted all of your code.

The issue for me trigger clicks only can be run after the page fully loaded so I bind my code after window load() and set timeout
Here I solved it
jQuery(window).on('load', function() {
setTimeout(function(){
//your code here
console.log('All assets are loaded');
jQuery('.wcpf-input-checkbox[value="hoodie"]').trigger('click');
jQuery('.wcpf-button-action-filter').trigger('click');
}, 1000);
})

jQuery load function not working on binding

I bind "load" and "change" in jQuery code.
My goal is: disable some field based on logic when page load.
jQuery( document ).ready(function() {
//Question 34.1
jQuery('select#fever').bind('load change', function () {
var drug_reaction = jQuery(this).val();
if(drug_reaction== 1){
jQuery('input#fever_days').attr('disabled',false);
jQuery('select#character_of_fever').attr('disabled',false);
jQuery('select#evening_raise_of_temparature').attr('disabled',false);
jQuery('select#night_sweats').attr('disabled',false);
}else{
jQuery('input#fever_days').val("");
jQuery('input#fever_days').attr('disabled',true);
jQuery('select#character_of_fever').val("");
jQuery('select#character_of_fever').attr('disabled',true);
jQuery('select#evening_raise_of_temparature').val("");
jQuery('select#evening_raise_of_temparature').attr('disabled',true);
jQuery('select#night_sweats').val("");
jQuery('select#night_sweats').attr('disabled',true);
}
});
});
When I change fever dropdown , its working. But when page load, I fetch data from Database and this code not working:
var drug_reaction = jQuery(this).val();
if(drug_reaction== 1){
jQuery('input#fever_days').attr('disabled',false);
jQuery('select#character_of_fever').attr('disabled',false);
jQuery('select#evening_raise_of_temparature').attr('disabled',false);
jQuery('select#night_sweats').attr('disabled',false);
}else{
jQuery('input#fever_days').val("");
jQuery('input#fever_days').attr('disabled',true);
jQuery('select#character_of_fever').val("");
jQuery('select#character_of_fever').attr('disabled',true);
jQuery('select#evening_raise_of_temparature').val("");
jQuery('select#evening_raise_of_temparature').attr('disabled',true);
jQuery('select#night_sweats').val("");
jQuery('select#night_sweats').attr('disabled',true);
}

load events fire on elements which load data from a URL (e.g. the whole page, img elements and iframe elements).
A select element doesn't load external data, and nor do any of its descendants. There is no load event.
Even if there was, it would have already loaded by the time the ready event fires.
Trigger the change event as part of your ready event handler instead.
jQuery('select#fever')
.bind('change', function () { ... })
.trigger("change");

Bind click to images loaded via AJAX

I've been having some trouble with this block of code, and I think I've finally narrowed the problem down. Here's the jQuery function...
$(document).ready(function(e) {
$('#formattingSection').load ('formattingdoc.html #formatting');
$('#loadFormatting').click(function() {
$('#formattingSection').load ('formattingdoc.html #formatting');
});
$('#loadSmileys').click(function() {
$('#formattingSection').load ('formattingdoc.html #smileys');
});
$('#formattingSection div img').click(function() {
var code = $(this).attr("title");
alert (code);
$('wallpost').val($('wallpost').val() + code);
});
});
Basically, it works like this. The page loads, we load part of a doc via AJAX. There are four buttons on the page, each one loads a new section via AJAX. When you click #loadSmileys, it will load via AJAX several images and display them in the DIV.
I'm binding a click() event to those images... but what I've found is that since the images aren't on the page at load time, the click event never gets bound. When I strip all the code away and load the images without AJAX, the click binds okay.
So... my question here... is there a way to bind the click event to the images AFTER they are loaded via AJAX?
For reference... I did make a jsBin HERE, but it's basically just hard coding the images to that I can see it works without the AJAX stuff going on.

Try:
$("#formattingSection").on("click","div img",function() {
var code = $(this).attr("title");
alert (code);
$('wallpost').val($('wallpost').val() + code);
});
As $.on attaches event handler to the parent and all events from children are delegated to the parent
Documentation

Yes, you totally can attach event handles to DOM nodes loaded on-the-fly. The trick is to use jQuery.get instead of .load. .get allows you to add an additional callback function that gets executed upon AJAX completion - the perfect place for you to add your $("#formattingSection div img") code. Here's what it would look like:
$('#loadSmileys').click(function() {
$('#formattingSection').get ({
url: "formattingdoc.html",
success: success
});
});
function success() {
$('#formattingSection div img').click(function() {
var code = $(this).attr("title");
alert (code);
$('wallpost').val($('wallpost').val() + code);
});
}

$('#formattingSection').load ('formattingdoc.html #formatting', function( response, status, xhr ) {
loading_completed();
});
function loading_completed()
{
$('#formattingSection div img').click(function() {
var code = $(this).attr("title");
alert (code);
$('wallpost').val($('wallpost').val() + code);
});
}
Try this

$('#loadSmileys').click(function() {
$('#formattingSection').load ('formattingdoc.html #smileys', function() {
$('#formattingSection div img').click(function() {
var code = $(this).attr("title");
alert (code);
$('wallpost').val($('wallpost').val() + code);
});
});
});

You should use the 'on' method. This can apply click handlers to elements created after the on method is called.
e.g.
$("#formattingSection").on("click","div img",function() {
...
}
As imges are added, they will automatically get the click handler functionality.
This question I asked helps explain the difference: jquery use of bind vs on click

How can I get Iframe event before load?

In my site, I use an iframeA in an iframeB, and, when the iframeA changes it's content I have to set the src. I can set it only with the onload event, but this called when the site is loaded. I am looking for some event or trigger, that helps me detect the location/src change before it starts loading. I don't want to wait the whole page load, before the src set. I have no direct access to iframeA (just the script below)
Some code:
var myframe = document.getElementById('frameB').contentWindow.document.getElementById('frameA');
myframe.onload=function (funcname) {...};

Check this gist or my answer to this question. The code there does exactly that:
function iframeURLChange(iframe, callback) {
var unloadHandler = function () {
// Timeout needed because the URL changes immediately after
// the `unload` event is dispatched.
setTimeout(function () {
callback(iframe.contentWindow.location.href);
}, 0);
};
function attachUnload() {
// Remove the unloadHandler in case it was already attached.
// Otherwise, the change will be dispatched twice.
iframe.contentWindow.removeEventListener("unload", unloadHandler);
iframe.contentWindow.addEventListener("unload", unloadHandler);
}
iframe.addEventListener("load", attachUnload);
attachUnload();
}
It utilizes the unload event. Whenever a page is unloaded, a new one is expected to start loading. If you listen for that event, though, you will get the current URL, not the new one. By adding a timeout with 0 milliseconds delay, and then checking the URL, you get the new iframe URL.
However, that unload listener is removed each time a new page is loaded, so it must be re-added again on each load.
The function takes care of all that, though. To use it, you only have to do:
iframeURLChange(document.getElementById("myframe"), function (url) {
console.log("URL changed:", url);
});

What will be changing the source of the iframe? If you have access to that code then you can do whatever is in your onload function then.
If a link has it's target attribute set to the iframe and that is how the source is changing then you can hi-jack the link clicks:
$('a[target="frameB"]').bind('click', function () {
//run your onload code here, it will run as the iframe is downloading the new content
});
Also, just a side-note, you can bind an event handler for the load event in jQuery like this:
$('#frameB').bind('load', function () {
//run onload code here
});
UPDATE
SITE -> frameB -> frameA
$("#frameB").contents().find("#frameA").bind('load', function () {
//load code here
});
This selects the #frameB element (that is in the current top level DOM), gets it's contents, finds the #frameA element, and then binds an event handler for the load event.
Note that this code must be run after #frameB is loaded with the #frameA element already present in it's DOM. Something like this might be a good idea:
$('#frameB').bind('load', function () {
$(this).contents().find('#frameA').bind('load', function () {
//run load code here
});
});
UPDATE
To hi-jack links in the #frameB element:
$('#frameB').contents().find('a[target="frameA"]').bind('click', function () {
/*run your code here*/
});
This will find any link in the #frameB element that has its target attribute set to frameA and add a click event handler.
And again, this will only work if the #frameB iframe element has loaded (or atleast gotten to the document.ready event) so you can select it's elements.

You could also try taking the approach of detecting when your iframe is going to leave its current location. This may be useful in some situations. To do this, put the following code in you iFarme source.
$(window).on('beforeunload', function () {
alert('before load ...');
});

I think adding inline onload attribute with appropriate event handler to iframe tag will solve your problem.
function onIframeLoad(){
//Write your code here
}
Markup change
<iframe src='..' onload='onIframeLoad()' />

How to prevent repeat in jQuery function?

I have a simple jQuery function as
$('.button').click(function(){
$("#target").slideToggle().load('http://page');
});
By slideToggle behavior, every click cause a slide, but the problem is that it will load url again too.
How can I limit the load() function to be performed only once, but slideToggle() on every click. In other words, how to prevent load() (only load, not the entire function) in the subsequent clicks?

$('.button')
.on('click.loadPage', function() {
$("#target").load('http://page');
$(this).off("click.loadPage");
})
.on('click.slideToggle', function(){
$("#target").slideToggle();
});
and another way without global vars:
$('.button')
.on('click', function() {
if ( !$(this).data("loaded") ) {
$("#target").load('http://page');
$(this).data("loaded", true);
}
$("#target").slideToggle();
});

Have a variable (global) which says whether it has been loaded or not. E.g:
var loaded = false;
$('.button').click(function(){
if(!loaded){
$('#target').load('http://page');
loaded = true;
}
$("#target").slideToggle();
});
This will cause the slideToggle to occur on every click, but the page to load only the once. :)
