If you have found that onclick event does not work on Google Chrome, Firefox and Safari web browsers, then here is quick way to fix it:

Replace onclick form id with its name

For example, let’s say you have the following:

id=”form1″ name=”checkform1″

Find JS event:

onclick=”document.form1.cSSld.value=””

Replace with:

onclick=”document.checkform1.cSSld.value=””

All set. It now works with all web browsers.
