Call js function after div is loaded

jquery run script after everything loaded

jquery after page load
html run javascript on div load
call javascript function()( $('div onload event))
jquery event after page fully loaded
javascript execute after all scripts loaded

I have a div element which is loaded after a click on a radio button.

Need to hide a part of the div after it is loaded.

$(function($) {
  $('.div_element').on('load', function() {

The above code doesn't work. I need to trigger a function after the div is shown on the page.

Although it may not be good solution but you can check in an interval if the div exist, if it is then you can do further:

$(function() {
    var checkDiv = setInterval(function(){
       if($('.div_element').length > 0) {    // it would be good if you would use id instead of the class
           //further action here
    }, 100); // check after 100ms every time

[RESOLVED] How to execute function after div loads , How to execute function after div loads heres my function, if div exists return "true"​, now how to $("#div1").load(function() { alert("The div has been loaded. One way to do it is to put the call to When chkObject(elemId) returns true, clear the setInterval() and then execute whatever javascript you need. A function can be executed when the page loaded successfully. This can be used for various purposes like checking for cookies or setting the correct version of the page depending on the user browser. Method 1: Using onload method: The body of a webpage contains the actual content that is to be displayed.

Here is how I would go about it. This is using vanilla JavaScript but it can easily be adapted to use jQuery.

The idea is to use Mutation Observers. I hope it helps.

        // After the document loads...
        document.onload = function () {

            var radios = document.forms["radios"].elements["gender"];
            for (var i = 0, max = radios.length; i < max; i++) {
                radios[i].onclick = function (event) {
                    var radio = || event.srcElement;
                    if (radio.value === "female") {
                        document.getElementById("female").style.display = "block"

            // Get the div whose change in attributes we are interested in.
            var targetNode = document.getElementById("femaleDiv");

            // Set the mutation observer to only listen to attribute mutations
            var config = { attributes: true };

            // This will be called when a mutation has been observed
            var callback = function(mutationsList) {
                for (var mutation of mutationsList) {
                    if (mutation.type == "attributes") {

            // Create the observer
            var observer = new MutationObserver(callback);

            // Start observing

DOMContentLoaded vs jQuery.ready vs onload, How To Decide , A simple explanation of how to decide when your JavaScript code should run. The load event occurs when all of the HTML is loaded, and any subresources innerHTML = new Date }); </script> <div id="my-awesome-el"></div> </body> </​html> DOMContentLoaded / jQuery.ready often occurs after the page has initially  This tutorial shows how to call a javascript function on page load using various plain JavaScript functions and using JQuery on document ready. The script.js is located in the same directory as the html page.

Check Div is initialized

       var textBox="<input type='text' class='textbox'>";
       var divNew="<div class='div_element'>DIV to Load</div>";
          var divNew1="<div class='div_element'>DIV to Load 2</div>";

HTML onload Event Attribute, Execute a JavaScript immediately after a page has been loaded: <body onload="​myFunction()"> Value, Description. script, The script to be run on onload  Calling the toggle2 function using window.onload in the bottom of an external js file placed near the bottom of the page reveals in the alert() statement that there is no value to style.display. The style is set to block in the CSS file.

As far as my understanding, you need to perform an action on clicking of a radio button. This is where your code should start.

//I suggest to use a same class for both the radio buttons you want to click as this will effect for all the radio buttons
    console.log('You clicked radio!');
    var checkDivLength = setInterval(function(){
   if($('.div_element').length > 0) {

      //Hide your element
   }, 100);

Please note that in this line "$("input[name='YOUR_BUTOTN_NAME_GOES_HERE']").click(function(){" you need to give the name attribute which you have used in your code. Eg <input type="radio" name="sample" value="test"> then your code should be "$("input[name='sample']").click(function(){"

Thanks :)

  • A <div> doesn’t "load". Do you want to call a function as soon as the <div> is in the DOM? Search for Mutation Observers. If the <div> isn’t in the DOM, then you can’t bind an event listener to it.
  • Can you add woking snippet of your code? That would be easy and faster to debug
  • @Xufox Yes, the div is shown on the page after radio button is clicked. I then need to say hide one of the textbox in the div that is loaded.
  • @phpblogger what is your code to hide?
  • @KiranShahi Updated the question. The duplicate link has the first param as "some url" - I dont have anything to use on that place, is there any other possibility?
  • This works. Thanks. but as expected takes more time to load the main div :-(. Sad that there is no onload event for the element which can just act based on the visibility of the div
  • Already tried this - it doesn't work after the div is loaded. Just checks on page load if the div is present on not.
