jQuery: enabling/disabling datepicker

Question

In my php-file, I want to use the jQuery Datepicker.

When my file loads, I create the Datepicker disabled.

Then, when a special field in my php-file (it is a form) is filled, I want to enable the Datepicker.

So, initially my Datepicker looks like this:

$("#from").datepicker({
    showOn: "both",
    buttonImage: "calendar.gif",
    buttonImageOnly: true,
    buttonText: "Kalender",
    showAnim: "drop",
    dateFormat: "dd.mm.yy",
    changeMonth: true,
    changeYear: true,
    showButtonPanel: true,
    showWeek: true,
    firstDay: 1,
    dayNamesMin: ["So", "Mo", "Di", "Mi", "Do", "Fr", "Sa"],
    weekHeader: "KW",
    disabled: true,
    onClose: function(selectedDate) {
        $("#to").datepicker("option", "minDate", selectedDate);
    }
});

This works just fine, no problem so far. The problem comes, when I want to disable the field.

If a special field is filled, I call $("#from").datepicker('enable');

This also works fine, BUT now I want to disable it again if the special field I mentioned it empty again.

Then I use $("#from").datepicker('disable'); and the field itself is grayed, but I can still use the field to enter values, the calender pops up and even the calender-image next to the box is clickable.

Anyone has an idea why this is the case? Am I missing something?

$("#from").datepicker('disable'); should work, but you can also try this:

$( "#from" ).datepicker( "option", "disabled", true );
