Jquery UI autocomplete combobox button click event

Question

I'm experiencing weird behavior with jquery ui autocomplete when using it to create a combobox. Whenever I click on the scrollbar to scroll through the list of results AND then click on my combobox button to close the results the results list closes and then opens again. I expect it to close the menu.

Steps to Repro

1. open jsfiddle demo
2. Type 'i' in the autocomplete OR hit the dropdown button.
3. Click on the vertical scroll to scroll the results
4. Click on the dropdown button

Script to Create Button

 this.button = $("<button type='button'>&nbsp;</button>")
    .attr({ "tabIndex": -1, "title": "Show all items" })
    .insertAfter(input)
    .button({
         icons: {
             primary: "ui-icon-triangle-1-s"
         },
         text: false
    })
    .removeClass("ui-corner-all")
    .addClass("ui-corner-right ui-button-icon")
    .click(function () {

        // when i put breakpoint here, and my focus is not on input, 
        // then this if steatment is false????

        if (input.autocomplete("widget").is(":visible")) {
            input.autocomplete("close");
            return;
        }

        // work around a bug (likely same cause as #5265)
        $(this).blur();

        // pass empty string as value to search for, displaying all results
        input.autocomplete("search", "");
        input.focus();
});

CSS (force long results menu to scroll)

.ui-autocomplete {
    max-height: 100px;
    overflow-y: auto;
    /* prevent horizontal scrollbar */
    overflow-x: hidden;
    /* add padding to account for vertical scrollbar */
    padding-right: 20px;
}
/* IE 6 doesn't support max-height
 * we use height instead, but this forces the menu to always be this tall
 */
* html .ui-autocomplete {
    height: 100px;
}

My solution could be closing the widget even if focus is transferred to widget itself and not the input element?

Any ideas how to modify this code so it behaves this way?

Answer 1

Based on issues with the various click and mouse events for the automplete widget, I came up with this: jsFiddle example.

jQuery:

var input = $('#txtComplete');

var data = [];
var isOpen = false;

function _init() {
    for (var idx = 0; idx <= 100; idx++) {
        data.push('item: ' + idx);
    };
    input.autocomplete({
        source: data,
        minLength: 0,
        open: function(event, ui) {
            isOpen = true;
        },
        select: function(event, ui) {
            isOpen = false;
        }
    });
}

function afterInit() {
    var button = $("<button type='button'>&nbsp;</button>").attr("tabIndex", -1).attr("title", "Show all items").insertAfter(input).button({
        icons: {
            primary: "ui-icon-triangle-1-s"
        },
        text: false
    }).removeClass("ui-corner-all").addClass("ui-corner-right ui-button-icon").click(function(event) {
        input.focus();
        if (isOpen) {
            input.autocomplete("close");
            isOpen = false;
        } else {
            input.autocomplete("search", "");
            event.stopImmediatePropagation();
        }
    });
}
$(window).click(function() {
    input.autocomplete("close");
    isOpen = false;
});
$(function() {
    _init();
    afterInit();
});​
