jQuery不会出错或成功 [英] jquery doesnt go to error or success

问题描述

与此相关:我如何将自动完成功能连接到文本框?

我正在尝试将自动完成(从jquery ui)链接到文本框. 我有以下内容:

Im trying to link autocomplete (from jquery ui) to a textbox. I've got the following:

$("#txtTags").autocomplete({
        minLength: 0,
        source: function(request, response) {   
            $.ajax({
                type: "POST",
                url: "GetTags.asmx/GetTags",
                dataType: "xml",
                contentType: "text/xml; charset=utf-8",
          success: function(xml) {
               alert("hi");
               // Completion logic goes here
          },
                error: function (XMLHttpRequest, textStatus, errorThrown) {
                    alert(textStatus);
                }
            });
        },    
    });

为什么我不能从成功函数或错误函数中得到alert?我必须使用dataType XML，因为那时(2002/2003年)不支持古老的.net 1.1应用程序json/jsonp. GetTags.asmx是我的Web服务方法.但是，当我在文本框中键入内容时，我当然不会出现任何错误，也不会得到自动完成选择.

Why do I not get either alert from the success function or the error function? I have to use the dataType XML because I am on an ancient .net 1.1 application json/jsonp was not supported back then (2002/2003). GetTags.asmx is my web service method. But of course I do not get any errors nor do I get an autocomplete selection when I type in my textbox.

更新:

解决了成功问题，所以我确实使用了成功功能，问题是为什么我的自动完成文本框仍然空白?在此问题顶部的第一个链接中，我已经从数据库中获取自动完成数据，将其存储为字符串数组，并将其返回到webmethod中.我必须在jquery中做什么才能获取此数据?

Fixed the success issue so I do get to the success function, question is how come my autocomplete textbox still comes up empty? In my first link posted at the top of this question I am already getting my autocomplete data from the database, I store it as a string array and I return it in my webmethod. What must I do in jquery to get this data?

这是我从chrome/运行webservice(.asmx)文件后的xml文件，即:

Here is the xml file after I run the webservice (.asmx) file from chrome / ie:

This XML file does not appear to have any style information associated with it. The document tree is shown below.

推荐答案

从xml中创建数组，并将其传递给这样的响应-

create array out of your xml and pass it to the response like this -

 success: function(xml) {
    var data = [];    
    $(xml).find('string').each(function(){ 
         data.push($(this).text());
    });
    response(data);
},
