Hi,

I need your help please.

I'm trying to validate an email address 

function ValidateData() {
        //debugger;
        var StartCreateDate = $('#FromCreatedDate').val();
        var EndCreateDate = $('#ToCreatedDate').val();
        var StartMigrationDate = $('#FromMigrationDate').val();
        var EndMigrationDate = $('#ToMigrationDate').val();
        var SendToEmail = $('#SendEmailTo').val();
       
        if ((StartCreateDate != null && EndCreateDate != null) && (StartCreateDate > EndCreateDate)) {
            alert("From create date must be greater than to create date")
            return false;
        }
        if ((StartMigrationDate != null && EndMigrationDate != null) && (StartMigrationDate > EndMigrationDate)) {
            alert("From migration date must be greater than to migration date")
            return false;
        }
        if (SendToEmail "doesn't have the correct format")  //Here I want to validate my email address $('#SendEmailTo').val();
        {
            alert("Email format is incorrect")
            return false;
        }

        return true;
    }

Try using a regular expression pattern, that's a pretty common approach.  Of course, if you google around you will find a variety of patterns for validating email addresses, some too simple, some too complex, you will have to judge your needs.  Here's an example one.

function ValidateData() {
        //debugger;
        var StartCreateDate = $('#FromCreatedDate').val();
        var EndCreateDate = $('#ToCreatedDate').val();
        var StartMigrationDate = $('#FromMigrationDate').val();
        var EndMigrationDate = $('#ToMigrationDate').val();
        var SendToEmail = $('#SendEmailTo').val();
        var ValidEmail = /^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$/;
       
        if ((StartCreateDate != null && EndCreateDate != null) && (StartCreateDate > EndCreateDate)) {
            alert("From create date must be greater than to create date")
            return false;
        }
        if ((StartMigrationDate != null && EndMigrationDate != null) && (StartMigrationDate > EndMigrationDate)) {
            alert("From migration date must be greater than to migration date")
            return false;
        }
        if (!ValidEmail.test(SendToEmail))
        {
            alert("Email format is incorrect")
            return false;
        }

        return true;
    }

Not sure your environment, but in a couple of bare bones tests here the part I suggested seems to work...

it's an issue with your code editor not with the code itself or maybe another block of your page
