I want to run a function when the page is loaded, but I don’t

  • 0

I want to run a function when the page is loaded, but I don’t want to use it in the <body> tag.

I have a script that runs if I initialise it in the <body>, like this:

function codeAddress() {
  // code
}

<body onLoad="codeAddress()">

But I want to run it without the <body onload="codeAddress()"> and I have tried a lot of things, e.g. this:

window.onload = codeAddress;

But it is not working.

So how do I run it when the page is loaded?

    window.onload = codeAddress; should work – here’s a demo, and the full code:

    <!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <script type="text/javascript">
        function codeAddress() {
            alert('ok');
        }
        window.onload = codeAddress;
        </script>
    </head>
    <body>
    
    </body>
</html>
    <!DOCTYPE html>
<html>
    <head>
        <title>Test</title>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <script type="text/javascript">
        function codeAddress() {
            alert('ok');
        }
        
        </script>
    </head>
    <body onload="codeAddress();">
    
    </body>
</html>
