Question

I want to enter only 3 words in a textbox. My JavaScript code is below:

jQuery('#Txt_Report').keyup(function (event) {
   if (event.which == 32) {
      count = jQuery('#Txt_Report').val().split(' ').length;
      if (count > 2) {
         /////////////
         //How can I stop entering text in txt_report anymore?
         /////////////
      });
   }
}

As you see, I want to block user to not to enter more than 3 words. If someone knows how to handle this please help.

You can’t preventDefault using keyup. Using keydown or keypress should work. Here is the example:

$('#Txt_Report').keypress(function(e) {
   if (e.which == 32) {
      var count = this.value.split(' ').length;
      if (count > 2) {
         e.preventDefault();
      }
   }
});
