Hi all
I am new to javascript and trying to validate a form text field only for alphabets. If there are no alphabets, it will alert the user. I have tried to comment onclick in my program because the website is not letting me post it with that

onBlur should work (in place of onClick), in order to capture when the user leaves that field.

To clarify, the onBlur could be on the input/text, not in place of the onClick for the button.

Also, I *think* that if you do this:


that a true/false returned from formValidator will determine whether the form is posted, which is what you want, correct?

Yes, that is what I want. Is there any debugger for javascript? I think that the logic is right but I have made a mistake in the typing of the code. I tried installing JSEclipse plugin for the same purpose but it doesn't let me edit html files. I dont know how to do it atleast.
Thanks
