jquery - 在 Struts 2 中使用 jQuery JSON 格式时无法呈现响应

Question

我在加载 select 标记的响应时遇到问题。我正在尝试根据第一个更改选择框。

为此，我使用带有 jQ​​uery Ajax 标记的 Struts 2。我想我已经拥有了所有必需的东西，但响应没有标记到选项，而是能够在浏览器的 View 源的 JS 中看到结果。

下面是我用JSP编写的代码。

这是我的第一个选择框:

<div class="type-text">
  <s:url id="remoteurl" action="getGlobalManufacturerJquery.action?mainId=title&subId=Add Title&selectedManufacturer=strUser&gameFileID=%{gameFileID}&gameFileName=%{gameFileName}&titleName=%{titleName}&titleID=%{titleID}"/>
                <sj:select 
                    href="%{remoteurl}" 
                    formIds="TitleGameHandsetsForm"
                    id="manufacturerName%{titleGameFilemappingID}" 
                    onChangeTopics="reloadsecondlist" 
                     name="manufacturerName%{titleGameFilemappingID}"
                    list="%{manufacturers}" 
                     listKey="%{globalManufacturer}"
                    
                    listValue="%{globalManufacturer}" 
                    emptyOption="true" 
                    headerKey="-1" 
                    headerValue="Select Global Manufacturer" 
                />
          </div>

下面是我的第二个选择框，应该更改第一个值

 <div class="type-text">        
                 <s:url id="remoteurl" action="getGlobalModelJquery.action?mainId=title&subId=Add Title&selectedManufacturer=strUser&gameFileID=%{gameFileID}&gameFileName=%{gameFileName}&titleName=%{titleName}&titleID=%{titleID}"/>
                <sj:select 
                     
                    id="globalModel%{titleGameFilemappingID}" 
                    formIds="TitleGameHandsetsForm" 
                    reloadTopics="reloadsecondlist" 
                    name="modelFromSelect" 
                    list="%{modelList}" 
                    emptyOption="true" 
                    headerKey="-1" 
                    headerValue="Select Global Model"
                />
                </div>

并且在 JSP 中没有可用的列表。但是服务器代码正在获取结果，我可以在 JS 源代码中看到它无法附加到选择框的 JSP。

<select name="manufacturerName77" id="manufacturerName77">
<option value=""></option>
</select>
<script type='text/javascript'>
jQuery(document).ready(function () {
    var options_manufacturerName77 = {};
    options_manufacturerName77.datatype = "json";
    options_manufacturerName77.type = 'select';
    options_manufacturerName77.emptyoption = true;
    options_manufacturerName77.headerkey = "-1";
    options_manufacturerName77.headervalue = "Select Global Manufacturer";
    **options_manufacturerName77.list = "[Acer, A Panda]";**
    options_manufacturerName77.listkey = "Acer";
    options_manufacturerName77.listvalue = "Acer";
    options_manufacturerName77.jqueryaction = "select";
    options_manufacturerName77.id = "manufacturerName77";
    options_manufacturerName77.name = "manufacturerName77";
    options_manufacturerName77.oncha = "reloadsecondlist";
    options_manufacturerName77.href = "/ci/getGlobalManufacturerJquery.action";
    options_manufacturerName77.hrefparameter = "mainId=title&subId=Add Title&selectedManufacturer=strUser&gameFileID=3&gameFileName=dcdscd&titleName=Bubble boom chalenge&titleID=11";
    options_manufacturerName77.formids = "TitleGameHandsetsForm";
  

jQuery.struts2_jquery.bind(jQuery('#manufacturerName77'),options_manufacturerName77);

 });
</script>
          </div>

如果 URL 写入不正确，应返回列表 JSON 数据的操作将不会返回任何内容。您应该将 URL 写为

<s:url var="remoteurl" action="getGlobalManufacturerJquery">
  <s:param name="mainId" value="title"/>
  <s:param name="subId" value="Add Title"/>
  <s:param name="selectedManufacturer" value="strUser"/>
  <s:param name="gameFileID" value="%{gameFileID}"/>
  <s:param name="gameFileName" value="%{gameFileName}"/>
  <s:param name="titleName" value="%{titleName}"/>
  <s:param name="titleID" value="%{titleID}"/>
</s:url>
