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>
