jquery 自动完成错误

Question

我得到一个如下所示的函数：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js" type="text/javascript"></script>
<script src="/js/jquery-ui-1.8.13.custom.min.js" type="text/javascript"></script>

function getValues (fieldName, action){
            $("#" + fieldName).keyup(function () {
                if (this.value != this.lastValue){
                    if (this.timer) clearTimeout(this.timer);
                    this.timer = setTimeout(function () {
                        //$( "#"+fieldName ).autocomplete({source:"http://www.expat-job.com/ajax/" + action + "/keyword/" + $("#" + fieldName).val()});
                        $.ajax({
                            type: "POST",
                            dataType: 'json',
                            url:"http://www.expat-job.com/ajax/" + action + "/keyword/" + $("#" + fieldName).val(),
                            success:function(msg) {
                                //splitedmsg = msg.split(',');
                              $( "#"+fieldName ).autocomplete(msg);
                            }
                        });
                    }, 200);
                    this.lastValue = this.value;
                }
            });
        }

然后像这样调用它：

$('input').live('click', function() {

                var word = $(this).attr('id');
                var splitedWord = word.split('-');
                switch(splitedWord[1])
                {
                    case 'CompanyName':
                        getValues(word, 'cv-company');
                    case 'DegreeName':
                        getValues(word, 'degree-name');
                    case 'InstituteName':
                        getValues(word, 'institute-name');
                    case 'LanguageName':
                        getValues(word, 'language-name');
                    case 'CertificationName':
                        getValues(word, 'certification-name');
                    case 'SkillName':
                        getValues(word, 'skill-name');
                    case 'JobTitle':
                        getValues(word, 'job-title');
                }
            });

ajax 响应如下所示：

["Mondial Assistance","Mondial Assistance Asia Pacific","Mondial Assistance Group","Mondial Assistance Mauritius","Mondial Assistance Thailand"]

它是一个包装在 json_encode() 中的数组。

我的问题在于自动完成部分：

 $( "#"+fieldName ).autocomplete(msg);

我已经尝试了所有可能的方法来输入数据。我已经回显了一个字符串并将其拆分以获得一个数组。

我使用了不同的语法： $( "#"+fieldName ).autocomplete({source: msg});

我总是收到相同的错误消息：

$("#" + fieldName).autocomplete is not a function
success()cv (line 453)
msg = "["Mondial Assistance","...l Assistance Thailand"]"
F()jquery.min.js (line 19)
F()jquery.min.js (line 19)
X = 0

经过大量测试，我发现它可以通过这样的简单测试工作：

$( "#"+fieldName ).autocomplete({source: ["orange","apple","pear"]});

所以问题不在于函数丢失或库未加载或类似的情况。

现在的问题

是为什么？！

Answer 1

<script src="http://code.jquery.com/jquery-1.5.2.min.js"></script> 

<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.13/jquery-ui.min.js"></script> 

 $( "#"+fieldName ).autocomplete({source: msg} ); 

您没有设置源。

Answer 2

您使用自动完成小部件的方式过于复杂——该小部件实际上应该为您简化事情。您不需要：

1. 在 keyup/click 事件上调用此小部件
2. 设置超时
3. 进行 AJAX 调用

以下是如何使用它：

$("input.requires-autocomplete").each(function () { // add "requires-autocomplete" class to appropriate inputs
  var action;
  switch ($(this).attr("id").split("-")[1]) {
  case "CompanyName":
    action = "cv-company";
    break; // you need to add breaks
  case "DegreeName":
    action = "degree-name";
    break;
  case "InstituteName":
    action = "institute-name";
    break;
  case "LanguageName":
    action = "language-name";
    break;
  case "CertificationName":
    action = "certification-name";
    break;
  case "SkillName":
    action = "skill-name";
    break;
  case "JobTitle":
    action = "job-title";
    break;
  }
  $(this).autocomplete({
    minLength: 2, // widget waits until 2 or more characters are entered
    delay: 500, //  widget waits until 500 ms past the last keystroke
    source: function (request, response) { // specifying a URL that returns JSON/JSONP was enough
                                           // but in that case the server-side script must expect a query string parameter
                                           // "term" (text inside the control) and "callback" (for JSONP requests)
                                           // not your case so we do it manually
                                           // we call your script via getJSON
                                           // pass the text inside the control in the format expected by your script
                                           // and call the response funciton passing in the JSON data
                                           // the last statement is short-circuited by passing response as the second
                                           // parameter to getJSON, which effectively calls the response function
                                           // and passes in the response JSON data
      $.getJSON("http://www.expat-job.com/ajax/" + action + "/keyword/" + request.term, response);
    }
  });
});

如果去掉注释和 switch-case 逻辑，剩余的代码大约为 5-6 行。
