哪个事件在移出jquery-autocomplete小部件后被触发？

Question

我将jquery-UI1.9用于jquery-autocomplete小部件。我试图在悬停jquery自动完成菜单项列表的同时，将列表项的背景颜色改为蓝色，将字体颜色改为白色。我可以通过添加css类来更改悬停列表项时的背景颜色，也可以通过添加焦点功能来更改悬停列表项时的字体颜色。

_focus: function (event, ui) {
   event.preventDefault();     
    var htmlString= $('.ui-autocomplete').html();
    //Recently unFocused Element
    var foundUnFocusedEle = $(htmlString).find('.focusedElement');
    if(foundUnFocusedEle.length != 0) {
    var unFocusedEleId = $(foundUnFocusedEle).attr('id');
    var unFocusedEleHtml = $('#'+unFocusedEleId).html();
    if($(unFocusedEleHtml).hasClass('add-search-result-label') 
    && $(unFocusedEleHtml).hasClass('add-search-result-sublabel')) {
    $('#'+(foundUnFocusedEle).attr('id')).find('.add-search-result-label').removeClass('hover-search-result-label');
    $('#'+(foundUnFocusedEle).attr('id')).find('.add-search-result-label').addClass('search-result-label');
    $('#'+(foundUnFocusedEle).attr('id')).find('.add-search-result-label').removeClass('add-search-result-label');

    $('#'+(foundUnFocusedEle).attr('id')).find('.add-search-result-sublabel').removeClass('hover-search-result-sublabel');
    $('#'+(foundUnFocusedEle).attr('id')).find('.add-search-result-sublabel').addClass('search-result-sublabel');
    $('#'+(foundUnFocusedEle).attr('id')).find('.add-search-result-sublabel').removeClass('add-search-result-sublabel');
    }
    $('#'+unFocusedEleId).removeClass('focusedElement');
    }
    //ui-state-focus
var foundUiStateFocus = $(htmlString).find('.ui-state-focus');
            //console.log(foundUiStateFocus);
            if(foundUiStateFocus.hasClass('ui-state-focus')) {
                //console.log('it has ui-state-focus');
                var focusedEleId = $(foundUiStateFocus).attr('id');
                //console.log('id: '+focusedEleId);
                $('#'+focusedEleId).addClass('focusedElement');
                var focusedEleHtml = $('#'+focusedEleId).html();
                if($(focusedEleHtml).hasClass('search-result-label') && $(focusedEleHtml).hasClass('search-result-sublabel')) {
                    //console.log('it has search-result-label');
                    //console.log($('#'+(foundUiStateFocus).attr('id')).find('.search-result-label'));
                    $('#'+(foundUiStateFocus).attr('id')).find('.search-result-label').addClass('add-search-result-label');
                    $('#'+(foundUiStateFocus).attr('id')).find('.search-result-label').removeClass('search-result-label');

                    $('#'+(foundUiStateFocus).attr('id')).find('.search-result-sublabel').addClass('add-search-result-sublabel');
                    $('#'+(foundUiStateFocus).attr('id')).find('.search-result-sublabel').removeClass('search-result-sublabel');

                    $('#'+(foundUiStateFocus).attr('id')).find('.add-search-result-label').addClass('hover-search-result-label');
                    $('#'+(foundUiStateFocus).attr('id')).find('.add-search-result-sublabel').addClass('hover-search-result-sublabel');
                }
            }
        }

现在，当我悬停列表项目时，字体颜色和背景颜色发生了变化，但当我从小工具或移动到搜索文本框时。我需要用原始颜色而不是白色来改变字体颜色。所以我创建了mouseout / mouseleave函数，但是它没有被调用。有人能告诉我，当你将鼠标悬停在列表上，然后从小部件中出来时，哪个事件/函数会被调用吗？
