Summary Event handler ambiguity

Reported 2007-10-20 15:26:50 PDT
This code seems to behave differently in every browser I tested, and behavior in WebKit has been changing between versions. What should we be doing? <html><head><title>pressed</title> <script type=text/javascript> function ev_onclick() { document.write("Generated from script 1"); } function ev_onsubmit() { document.write("Generated from script 2"); } </script> <body> <form onsubmit=ev_onsubmit() action="" method=post><input onclick=ev_onclick() type=submit value="Submit Query"> </form><br> </body></html>

Firefox displays the submit handler and loads forever Opera, Konqueror display the submit handler and stop Safari 2 goes blank WebKit recent trunk goes back to the form

The click ev_onevent() function should fire first when you click the button. It replaces the document with a new document, and that ends that. So you should end up with a document that just says "Generated from script 1". Ok so I wrote that based on just my knowledge of HTML5. Now for reality. I tested IE7 and Mozilla trunk, and luckily for my credibility, both do exactly what I just described. Score!

I confirm that the above code behaves similarly in browsers. I tested in Chrome 124.0.6367.60, Firefox 124.0.2, and Safari 17.4.1. A button "Submit Query" gets displayed and the ev_onclick() function fires when clicking on the button and it is replaced with a new document "Generated from script 1".
