Question

I am trying to prevent a form from submitting if the length of input text field with the id “num” is less than 10. However it doesn’t seem to be working.

    $('#num').val().length;

See my code here in fiddler. Thanks.

Answer 1

You’re setting your v variable when the page is loaded. At this time, the string length is 0. You need to move that code one line down, beneath

$("#meetForm").submit(function(e){
// Put it here

Otherwise, the v variable is never updated, which is why you’re always getting 0.
