clearing input text boxes

if there is text(ie the value is "some text here")in a text box on a html form how do you clear it when the mouse is clicked inside it?

this thread belongs to html/js forum, sample of what you want is
<form name=myform>
<input name=a value=hello onClick="document.myform.a.value=''";>
</form>

i tried it but it gave me an error on the form inboth netscape and in ie

dunno...works fine for me

Try this instead
<form name=myform>
<input name=a value=hello onFocus="document.myform.a.value=''";>
</form>
I have no idea why Al's code didn't work, it should have, but I also had trouble in NS4.75 and with Opera 5.12.

could be that last ; ....
