Re: Will not SUBMIT if textbox empty

If you're willing to use JavaScript, the following is what I do:
 function Inspect(form){
  var dataIn0=document.forms[0].elements[0].value
    if (dataIn0 == "")
   {alert("You must enter a book title")
   document.forms[0].elements[0].focus()
   return false}
and then in the form tag:
<FORM METHOD="post" ACTION="BookEntry2.asp"
onSubmit="return Inspect(this.form)" id="form1" name="form1">
In this fashion, the form will not be submitted until the function Inspect()
returns true.
HTH,
Steve

Subject: Will not SUBMIT if textbox empty


| Is there a way to keep a <form> from submitting if nothing has been
entered
| in an input textbox (actually, in this instance, a type="file" input box)?
| The <form action= > is the same page.  I would like to have NO Request
| Object (ASP) initiated if the input has nothing entered (a file chosen for
| upload).  I'm dealing with multiple forms on a single page and mixing
| BinaryRead method forms and Request.Form collections forms and have worked
| out how to keep one from interfereing with the other, but I just know
| someone is going to hit the SUBMIT button (BinaryRead) without selecting a
| file and give an ugly error page.
