JavaScript page loaded code example

Example 1: JavaScript that executes after page load

//two ways of executing JS code after page is loaded, use "DOMContentLoaded" when able

document.addEventListener("DOMContentLoaded", function(){
    //dom is fully loaded, but maybe waiting on images & css files
});

window.addEventListener("load", function(){
    //everything is fully loaded, don't use me if you can use DOMContentLoaded
});

Example 2: how to call a function as soon as a page loads javascript

<body onload="yourFunction()"> </body>

Example 3: call a function when page is loaded

<script src="js/jquery-1.11.0.min.js" type="text/javascript"></script>
<script type="text/javascript">

    $(document).ready(function () {
        yourFunction();
    });
    function yourFunction(){
      //some code
    }
</script>

Example 4: run on load js

function codeAddress() {
            alert('ok');
        }
window.onload = codeAddress;

Example 5: html tag run only after whole page is loaded
