jQuery autocomplete turn off

1st question

I have a dropdownlist, filled with countries (from xml file).

When you choose a country, you can use the autocomplete for a textbox. This autocomplete has postal codes from the choosen country.

Now I want to set the autocompl开发者_Go百科ete off right after the dropdownlist.change event for preventing that the autocomplete (filled with postal codes) for 1 country also work for another country. But how do you turn it off?

Code:

//when changing country, other postcodes will load
        $('[id$=landenDropDown]').change(function () {

            //autocompletes removal
            ...

            $('[id$=POSTCODETextBox]').html("");

            var LandCode = $('[id$=landenDropDown]').attr("value");

            //autocomplete with postal codes for Belgium
            if (LandCode == "BE") {
                //autocomplete postcode from selected country
                $('[id$=POSTCODETextBox]').autocomplete("PostcodeBE.aspx");

            }
             //autocomplete with postal codes for Holland
            else if (LandCode == "NL") {
                //autocomplete postcode from selected country
                $('[id$=POSTCODETextBox]').autocomplete("thingXml.aspx");

            }

            else {
                //test
                getal += 1;
                alert(getal);
            }

The problem is when the autocomplete is finished and select an other country that this autocomplete still exist, even when it doesnt have to show up.

Please view the documentation: (Doc)

$( ".selector" ).autocomplete({ disabled: true });

If this solution doesnt work for you, you might have somewhere other problems. Make your code a little better, maybe something is causing some internal errors

change

$('[id$=POSTCODETextBox]').html("");

to

$('[id$=POSTCODETextBox]').val("");

try to work like this for postcodetextbox:

$('[id$=POSTCODETextBox]').autocomplete({
      source: "somesource.aspx",
      change: function(event, ui) {
           $(this).autocomplete("destroy");
      }
});

But this will disable the user from using it again...

You could also disable the textbox.

$('[id$=POSTCODETextBox]').attr("disabled", "disabled");

    //when changing country, other postcodes will load
    $('[id$=landenDropDown]').bind($.browser.msie ? 'propertychange' : 'change', function () {

        //autocompletes removal
        ...

        var LandCode = $('[id$=landenDropDown]').attr("value");

        $('[id$=POSTCODETextBox]').autocomplete('destroy');

        //autocomplete with postal codes for Belgium
        if (LandCode == "BE") {
            //autocomplete postcode from selected country
            $('[id$=POSTCODETextBox]').autocomplete("PostcodeBE.aspx");

        }
         //autocomplete with postal codes for Holland
        else if (LandCode == "NL") {
            //autocomplete postcode from selected country
            $('[id$=POSTCODETextBox]').autocomplete("thingXml.aspx");

        }

        else {
            //test
            getal += 1;
            alert(getal);
        }
