Why Won't My Function Execute on Page Load?

How to Execute a Function Automatically Upon Page Load

When seeking to execute a function as soon as a page loads, developers may encounter issues if they attempt to avoid using the tag's onLoad attribute. Despite trying various alternatives, such as window.onload = codeAddress;, this approach may not yield the desired results.

To address this issue, it is essential to understand that the code provided in the example should indeed work. The following code snippet demonstrates how to execute a function named codeAddress upon page load:

<!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>

Copy after login

By incorporating this code into the section of the HTML document, the codeAddress function will be executed as soon as the page is loaded, ensuring that the desired actions are triggered promptly.
