Space 1

[Maximus007]

I have an input text field name:Username and the Form name: MyForm

I would like to alert the user if they enter any username with: spaces,',- or ,

Is that spaces, apostrophe, and minus, or spaces, apostrophe, minus, and comma? It's hard to tell from your list!

My mistake!
It is space between character, comma, dash and apostrophe

regexp to the rescue:

<script type="text/javascript">

function validateName(obj) {
   if (/[ \'\-,]/g.test(obj.value)) {
      alert("You have illegal characters in your name");
   }
   else {
      alert("that name is fine");
   }
}

</script>
<input type="text" id="blah" />
<input type="button" value="validate" onclick="validateName(document.getElementById('blah'))" />

Hmm.... I was gonna leave it at the subtle purple hint, but after looking at your profile I have to ask - any reason why you've asked 80 questions on TT and only given out 3 stars?

To be honest with you I don't know why I stop using it but going foward I will use it more frequently to show my appreciation. Is this how you get rated?

That's correct. Thanks for the star.
