My mission: User must enter both name and emial address into text box. Otherwise alert box says "please enter missing data".

If you submit the form with nothing at all (""), then there's no space, so the form is submitted.

Hi, guys. How are you?
Well, I have got another problem.

My mission:

User must enter both name and emial address into text box. Otherwise alert box says "please enter missing data".

Here is my code:

code:

<html>

<head>

<script type="text/javascript">

  function isBlank(theForm)

   {

     if ((theForm.first.value == " " )&#0124; &#0124; (theForm.last.value == " ")) 

   {

     alert("Please enter missing data.")

    }

   else

     {

      theForm.submit()

     }

   }



</script>

</head>

<body >

<form>

 <h3>Please enter your first name:</h3>

<input type="text" name="first"><br />

 <h3>Your last name:</h3>

<input type="text"  name="last"><br />

<input type="button" value="submit info" onClick="isBlank(this.form)">

</form>



</body>

</html>

I guess I have done enught to run the program. But alert box never pops up.....
