Do yourself a favor and remove that script code from the onclick handler and move it to a function:

onclick="Myfunction(this);"

<script type="text/javascript">
function MyFunction(el)  {
    ... do your JS stuff
}
</script>

You can also call this function from FoxPro code.

Here's a blog post that talks about calling script code in the Web Browser control.

Note that FoxPro can't mixed case functions and always looks for lowercase function names. So the function above should 'myfunction' if you want to call it from FoxPro.
