Fix regex in jquery validation plugin with twitter bootstrap popover -


i have code shows popover when there white space.

$.validator.addmethod(         "regex",         function(value, element, regexp) {             var re = new regexp(regexp);             return this.optional(element) || re.test(value);         });   $('#validateform').validate({      rules: {          product: {              required: true,              term: {regex: /^\s*$/}          }      },      messages: {          product: {              required: "a text much",              term: "please avoid spaces"          },      },         showerrors: function (errormap, errorlist) {           $.each(this.successlist, function (index, value) {              $('#'+value.id+'').popover('destroy');          });            $.each(errorlist, function (index, value) {               $('#'+value.element.id+'').attr('data-content',value.message).popover({                  placement: 'top',                  trigger: 'manual'              }).popover('show');           });       }   });

what happens is, popover doesnt destroyed once there no whitespace. doing wrong?

this regular expression valid both white-space , empty string.

if want match white-space, should use regex: /^\s+$/
