Getting unload to work with a button cross-browser's

I am wondering if I can have the unload method in Javascript do a button.click; or a document.getElementById('target').click();

The reason for this is I want to clear the information in the browser but I can't seem to get the unload method to work right. But I don't even know if the unload method is capable of doing a button.click or a document.getElementById('target').click(); Is there like a list of things this method can or cannot do? here is the code I am trying to get working.

  window.onunload=leave;

     function leave() {
//alert("Leaving");
    document.getElementById('kioskform:broswerCloseSubmit').click();
   
}

The alert seems to be showing in everything ("IE, FireFox,Safari") but in Chrome ('don't know why) but i can't seem to get the clear options i am using to work with the unload method. Not to mention I am wondering if there is a good way to detect which browser the individual is using to load in different parts of the unload script any idea's or suggestions or advice is greatly appreciated.

Solution

  • If you were to use jQuery , you could use the DirtyForm plugin. This would accomplish what you are trying to do.
