How to disable/enable input field on click with jQuery

Question

How to properly enable/disable input field on click with jQuery?

I was experimenting with:

$(\"#FullName\").removeAttr(\'disabled\');

Answer 1

To toggle a field between disabled and enabled, try this:

$('#toggle_button').click(function () {
    $('#FullName').prop("disabled",

    function (i, val) {
        return !val;
    });
})
