我的页面上有一个相当简单的 jquery-ui 自动完成框。HTML 很简单，如下所示：
<div class="control-group">
<label for="addCampaignUser"></label>
<div class="controls">
<input id="addCampaignUser" />
<button id="addCampaignUserButton">Add User</button>
</div>
</div>
JavaScript 有点复杂，但还算不错：
$('#addCampaignUser').autocomplete({
minLength: 2,
source: function (request, response) {
var term = request.term;
if (term in cache) {
response(cache[term]);
return;
}
$.post("@Url.Action("ForCampaignAutoComplete", "CustomerUser")", { "searchTerm": request.term })
.done(function (data) {
console.log('{request: ' + JSON.stringify(request) + "}");
console.log('{data: ' + JSON.stringify(data) + "}");
cache[request.term] = data;
response(data);
})
.fail(function (err) {
console.error(err);
});
},
select: function (event, ui) {
console.log(ui.item ? "Selected: " + ui.item.Name : "Nothing selected, input was " + this.value);
},
close: function(event, ui) {
console.log("closed: " + event);
}
})
.data("ui-autocomplete")._renderItem = function (ul, item) {
return $("<li>").append("<a>" + item.Name + " (" + item.CustomerName + ")</a>").appendTo(ul);
};
一切似乎都按预期工作：
问题是，只要我将鼠标悬停在列表中的任何项目上，或者如果我尝试通过向上/向下箭头选择其中一个项目，列表就会关闭，而不会选择任何内容（或触发selector事件）。focus
我尝试<a>在处理程序中删除 item.Name 周围的标签.data("ui-autocomplete")，如下所示：
.data("ui-autocomplete")._renderItem = function (ul, item) {
return $("<li>").append(item.Name + " (" + item.CustomerName + ")").appendTo(ul);
};
这解决了自动关闭问题，但没有任何东西被选中。
我已经尝试禁用所有可能会干扰的各种附加组件和库，但到目前为止还没有。我正在使用 jquery-2.0.3.js 和 jquery-ui-1.10.3.js。
我在做一些明显错误的事情吗？
