Can I use the onClick event for plain text?

Hi,

trying to call a function through the onClick event of text.
Another question is, can I declare the variable numsquare this way (inside the alert mehtod)?

I want to link text to the function. Something like;

<onclick=squareit(), "Square any number">

Am I at least close? :-(

Here's the function I wrote:

<script language="JavaScript" type=text/javascript>
<!--//
function squareit()
{
alert(var numsquare = prompt("Please enter in any number to be squared.") + "Thank you, " + numsquare + " squared is " + numsquare * numsquare ".")
}
//-->
</script>


TIA,
Tony

Works great! But you already knew that! :-P

So would the variable declaration not have worked?
Was it just plain old "bad form" to try to put all that in the alert() method?

Thanks again,
Tony

you cannot have var ... = prompt(.......... in a alert.

You should declare all variables either local or global and then in the alert you can show them as i did above.

Glad to have helped and thanks

thought you might ask...

I guess cause while you gave me code that worked, I have just as much desire to understand
why I am wrong. I try to use my reference materials for these answers, but they aren't clear about why things are done the way they are.

Such as "cannot have var ... = prompt(.......... in a alert."

Those answers are really important to me too.
Thanks again for help!
