Jquery Field Validation Onblur (mvc)

I want to have the fields in my form be validated after the user clicks out of them. However, I am not familiar with client side validation using Jquery. Can anyone explain how to

Solution 1:

This can be achieved with JS

var accName = document.getElementById('txtAccountName');
accName.addEventListener('blur', function () {
    if (accName.value != "") {
        //do something
    }
});

Updated Or in jQuery:

var accName = $("#txtAccountName");
accName.blur(function () {
    if (accName.val() != "") {
        //do something
    }
});
