不确定如何使用JQuery UI自动完成... :( [英] Not sure how to use the JQuery UI Autocomplete ... :(

问题描述

这是我问过以前的JQueryUI自动完成问题.

这一次，我要返回数据...但是我不知道如何我定义要显示的html以及如何用结果动态更新该html.

This time, I have my data returning ... but I have no idea how i define what html to show and how to dynamically update that html with my results.

所以，这是我的jquery....

So, here's my jquery ....

Home.js

function AutoComplete(element) {
    var cache = {};
    $(element).autocomplete({
        minLength: 2,
        source: function (request, response) {
            if (request.term in cache) {
                response(cache[request.term]);
                return;
            }
            else {
                $.getJSON("/api/autocomplete/" + 
                            encodeURIComponent(request.term),
                    function (data) {
                        cache[request.term] = data;
                        response(data);
                    });
            }
        }
    });
}

这已连接到我的视图

Index.aspx

<script type="text/javascript">
    $(document).ready(function () {
        AutoComplete("#searchQuestion");
    })
</script>

现在..我不确定我如何告诉它使用一些html/div/etc. ...然后填充该<ul>列表(我假设我在..上方扩展了回调，而不是调用此response(data)方法.. wtf是吗?)

Now .. i'm not sure how i tell it to use some (yet to be made) html/div/etc. ... and then to populate that <ul> list (i'm assuming i extend the callback, above .. instead of calling this response(data) method .. wtf is that?)

推荐答案

这是我的jQuery UI自动完成功能的工作示例.希望对您有所帮助:

Here's my working example of jQuery UI's autocomplete. Hope it helps:

    var cache = {};
    $("#textbox").autocomplete({
      source: function(request, response) {
       if (request.term in cache) {
        response($.map(cache[request.term].d, function(item) {
         return { value: item.value, id: item.id }
        }))
        return;
       }
       $.ajax({
        url: "/Services/AutoCompleteService.asmx/GetEmployees",  /* I use a web service */
        data: "{ 'term': '" + request.term + "' }",
        dataType: "json",
        type: "POST",
        contentType: "application/json; charset=utf-8",
        dataFilter: function(data) { return data; },
        success: function(data) {
         cache[request.term] = data;
         response($.map(data.d, function(item) {
          return {
           value: item.value,
           id: item.id
          }
         }))
        },
        error: HandleAjaxError  // custom method
       });
      },
      minLength: 3,
      select: function(event, ui) {
       if (ui.item) {
        formatAutoComplete(ui.item);   // custom method
       }
      }
     });

如果您现在不这样做，请获取 Firebug .这是Web开发的宝贵工具.您可以在此JavaScript上设置一个断点，然后看看会发生什么.

If you're not doing so by now, get Firebug. It's an invaluable tool for web development. You can set a breakpoint on this JavaScript and see what happens.
