jQuery event.preventDefault() Method

The event.preventDefault() method stops the default action of an element from happening.

For example:

• Prevent a submit button from submitting a form
• Prevent a link from following the URL
• 
  

$("a").click(function(event){
    event.preventDefault();
});

Prevent a link from opening the URL:

  function Redirct() {
            window.location.href = "webpages/dashboard.aspx";
        }

Jquery CHECKS IF THE KEY PRESSED IS A NUMERIC OR DECIMAL VALUE

  function isNumber(evt, element) {

            var charCode = (evt.which) ? evt.which : event.keyCode

            if (
                (charCode != 45 || $(element).val().indexOf('-') != -1) &&      // “-” CHECK MINUS, AND ONLY ONE.
                (charCode != 46 || $(element).val().indexOf('.') != -1) &&      // “.” CHECK DOT, AND ONLY ONE.
                (charCode < 48 || charCode > 57))
                return false;

            return true;
        }

  $('input[id$=txefetAmount],input[id$=txtsdfAmount],input[id$=txtsdAmount]').keypress(function (event) {

            return isNumber(event, this)

        });
