How to validate mobile number, email in jquery?

Definition :-

This tutorial will show you how to validate an email address and mobile number using jquery. This method has a few advantages over validating an email address using jquery, as the validation process takes place within the browser, meaning no server request or reload is necessary. 

Below is the jquery mobile, Email validation regular expression, mobile validation jquery regular expression which is for checking 10 digit number and first number should not be 0 and email validation jquery regular expressional which for checking global email format.

var mob = /^[1-9]{1}[0-9]{9}$/;

var eml = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;

if (eml.test($.trim($("#<%=txtEmail.ClientID %>").val())) == false) {

    alert("Please enter valid email address.");

    $("#<%=txtEmail.ClientID %>").focus();

    return false;

 }

if (mob.test($.trim($("#<%=txtMob.ClientID %>").val())) == false) {

    alert("Please enter valid mobile number.");

    $("#<%=txtMob.ClientID %>").focus();

    return false;

}

Note that this is merely a simple email validation function.
