Email validation is always required when we have a form or login / sign up pages. If we are using JQuery, the below regular expression will be simple and easy to use for validating an email address. Testemail = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i; So we can write this in a function : function TestValidEmail(sEmail) { var Testemail  = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/i ; if ( Testemail   .test(sEmail)) { return true; } else { return false; } }

below code snippet can be used to replace "-"  of select drop down values with ",". JQuery('#sel_test option:contains ("-")).each function(index,option)    {       var sval = JQuery(option).val().replace(/\-/g,",");       JQuery(option).val(sval);       JQuery(option).html(sval);     }

There are many ways to validate HH:MM format. Below function also can be used to validate HH:MM format. function ValidateTime(value) {   var timepattern = /^([0-9]|0[0-9]|1[0-9]|2[0-3]):[0-5][0-9]$/;   if (value.match(timepattern ))     {        return true;     }  return false; }
