Check for Blank Text Boxes

Question

I have a series of text boxes on a page, with common names Number and Scale:

<input type="text" name="Number">
<input type="text" name="Scale">

I also have my submit button:

<input type="SUBMIT" value="Process Now">

I am using jQuery on my webpage too - is there code that will check all instances of Number and Scale and not allow the user to submit until all the text Number and Scale text boxes have an entry in them?

What heve you tried? Your question _is there code that will check all instances of Number and Scale_ answer is __Yes__ — Satpal, May 21 '14 at 14:24

Try this:

var emptytxt= $('[name=Number],[name=Scale]').filter(function () {
  return $.trim($(this).val()) == '';
});
if (emptytxt.length) { /* Error. has one or more empty txtboxes with name Number,Scale */ }

Do I need to wrap this in anything... or can the jQuery start with `var`? – Dustin Cook May 21 '14 at 14:28
