Java-Script Validation can be used in portal in html , php , java etc .


1. Email Validation : We have used an Regex here , and compared the text in input with it and given an alert.

    function validateemail() {
        var ccc = document.getElementById( 'idemailtb').value;
        var reg = /^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$/
        if (!reg.test(ccc)) {
        alert( "Invalid Email Id");
          }
    }


2. Contact No. Validation : We have used an simple if condition that Number should be atlest of 10 in length.

    function permanentnumber() {
        var mob = document.getElementById( 'idcontactnotb').value;
        var count = mob.length;
        if (mob > 31 && (mob < 48 || mob > 57) && count == 10 ) { }
        else {
            alert( "Please Enter 10 Digit Number:" );
            return true;
        }
    }


2. Zipcode / Pincode Validation : We have used an simple if condition that ZipCode should be atlest of 6 in length and only a numerical value .

    function zipcode() {
        var zipcode = document.getElementById( 'idziptb').value;
        var length = zipcode.length
        if (length < 6)
            alert( "Please Enter Valid Zipcode:");
        if (zipcode > 31 && (zipcode < 48 || zipcode > 57)) { return false; }
        else {
            alert( "Please Enter Valid Zipcode:");
            return true;
        }
    }
