我正在使用自动完成功能，我想在列表中添加一个标题，这让我很复杂，我遇到了一些问题：这是我的代码：
var autocompleteCounselor = function () {
$(this.el).find('.alternateCounselorAutocomplete').autocomplete({
minLength: 0,
source: this.counselorValidDelegates,
focus: function (event, ui) {
console.log(ui);
$(".alternateCounselorAutocomplete").val(ui.item.NAME());
return false;
},
select: function (event, ui) {
onAutocompleteAlternateCounselorSelected.apply(_self, [event, ui, _self.counselorFullValidDelegates]);
}
}).data("ui-autocomplete")._renderMenu = function(ul, items){
var self = this;
ul.append("<li><span>Name</span>"+
"<span>Title</<span>" +
"<span>Phone</<span> "+
"<span>Location</<span>"+
"<span>Department</span></li>");
$.each(items, function(index, item){
/*return $("<li>")
.append("<div class='listcounsuler'><span>" + "<a>" + item.NAME() + "</a>" + "</span>" + "<span>" + item.TITLE() + "</span>" + "<span>" + item.PHONE() + "</span>" + "<span>" + item.LOCATION() + "</span>" + "<span>" + item.DEPARTMENT() + "</span>" + "</div>")
.appendTo(ul);*/
self._renderItem(ul, item);
});
/* ul.append("</tbody></table>");*/
};
$('.alternateCounselorAutocomplete').autocomplete().data("ui-autocomplete")._renderItem = function (ul, item) {
return $("<li>")
.append("<div class='listcounsuler'><span>" + "<a>" +
item.NAME() + "</a>" + "</span>" + "<span>" + item.TITLE() +
"</span>" + "<span>" + item.PHONE() + "</span>" + "<span>" +
item.LOCATION() + "</span>" + "<span>" + item.DEPARTMENT() +
"</span></div>")
.appendTo(ul);
};
$('.alternateCounselorAutocomplete').autocomplete("search", "");
$(this.el).find('.counselorEdit').on('click', function () {
$('.alternateCounselorAutocomplete').autocomplete('close');
});
};
菜单完美呈现，问题是当我将注意力集中在 li 上时，在控制台中我看到错误：Uncaught TypeError: Cannot call method 'NAME' of undefined
我看到焦点项目未定义：对象{项目：未定义}
函数渲染项也可以正常工作，我可以看到我想要的“li”。
我通过 _renderItemData 更改了 _renderItem 并且它继续发生，我尝试了几件事，但我无法得到解决方案。欢迎任何帮助。
