my own $(document).ready()

Question

I have the following problem: I've got a website that can't have dependencies to javascript-files. I want to have the same function as $(document).ready() in jquery. How would that look like? Thanks.

that's abit tough to do in javascript, but an easier alternative is to use `window.onload` but they are not the samething. — KJYe.Name 葉家仁, Apr 01 '11 at 14:27

onLoad works, but it waits until all images and stuff are loaded. If you just want it to run when the DOM is ready, you can do this (found here):

// Create onDomReady event
window.onDomReady = function(f){
    if(document.addEventListener){
        document.addEventListener("DOMContentLoaded", f, false);
    }
    // For IE
    else{
        document.onreadystatechange = function(){
            if(document.readyState == "interactive"){
                f();
            }
        };
    }
};

// Attach a callback to onDomReady
window.onDomReady(function(){
    alert("The DOM is ready!");
});

+1: I am amazed why you agreed in the comment that both are equal? – naveen Apr 01 '11 at 14:49
@yetanothercoder: I did, because while not exactly the same, maybe it's good enough for the OP. – Rocket Hazmat Apr 01 '11 at 15:30

You could just look at the jQuery source code. If you want a simple "emulation", just include/call your JavasScript as the last element of <body>

   <!-- ... start of your HTML document -- -->
   <script type="text/javascript">
      likeDocumentReady();
    </script>
  </body>
</html>

Before jQuery onLoad was a common practice, a much detailed answer in this link where you can check for cross browser solution.

I guess you're looking for the onload event. But yes123 is right, you should start accepting answers.

window.onload = function() {
    // yadda
}
