"Uncaught TypeError: Cannot read property 'length' of null JAVASCRIPT

Vote count: 0

I am using simple length function to check length greater than zero based on id. Code i am using is

if ($('#abcd').length > 0)
{
    var abcd = $('#abcd').val();
}

This code is working fine and producing no error. But if i am using simple javascript in this way

if (document.getElementById('abcd').length > 0)
{
    var abcd = document.getElementById('abcd').val();
}

Then it is not working and producing this error "Uncaught TypeError: Cannot read property 'length' of null". What does this error mean and how can i get this working ?
