JQGrid編輯模式：如何根據不同選擇列表中的選擇填充選擇列表

我有一個jqGrid，當我進入編輯模式時，我需要有2個選擇列表。我需要第二個列表根據選擇列表1中的選擇進行過濾。JQGrid編輯模式：如何根據不同選擇列表中的選擇填充選擇列表

這是我第一次嘗試使用jqGrid，因此我遇到了一些麻煩。

我見過一些使用硬編碼數組等的例子，但我需要從數據庫中提取信息，並且無法使其工作。

我想我需要讓我的手通過這一個。 :-p

我的問題的列是AssemblyTypeName和AssemblyName，我需要按順序填充它們。

我的jqGrid代碼如下：

$("#jqTable").jqGrid({ 
     // Ajax related configurations 
     url: '@Url.Action("_CustomBinding")', 
     datatype: "json", 
     mtype: "POST", 
     postData: { 
      programID: function() { return $("#ProgramID option:selected").val(); }, 
      buildID: function() { return $('#Builds option:selected').val(); } 
     }, 
     // Specify the column names 
     colNames: ["Actions", "Assembly ID", "Assembly Type", "Assembly Name", "Cost", "Order", "Budget Report", "Partner Request", "Display"], 

     // Configure the columns 
     colModel: [ 
     { name: 'myac', width: 80, fixed: true, sortable: false, resize: false, formatter: 'actions', formatoptions: { keys: true} }, 
     { name: "AssemblyID", key: true, index: "AssemblyID", width: 40, align: "left", editable: false }, 
     { name: "AssemblyTypeName", index: "AssemblyTypeName", width: 100, align: "left", editable: true, edittype: 'select', 
      editoptions: { 
       dataUrl: '@Url.Action("_AssemblyTypes")', 
       buildSelect: function (data) { 
        var response = jQuery.parseJSON(data); 
        var s = '<select>'; 
        if (response && response.length) { 
         for (var i = 0, l = response.length; i < l; i++) { 
          var ri = response[i]; 
          s += '<option value="' + ri + '">' + ri + '</option>'; 
         } 
        } 
        return s + "</select>"; 
       } 
      } 
     }, 
     { name: "AssemblyName", index: "AssemblyName", width: 100, align: "left", editable: true, edittype: 'select', 
      editoptions: { 
       dataUrl: '@Url.Action("_Assemblies")', 
       buildSelect: function (data) { 
        var response = jQuery.parseJSON(data); 
        var s = '<select>'; 
        if (response && response.length) { 
         for (var i = 0, l = response.length; i < l; i++) { 
          var ri = response[i]; 
          s += '<option value="' + ri + '">' + ri + '</option>'; 
         } 
        } 
        return s + "</select>"; 
       } 
      } 
     }, 
     { name: "AssemblyCost", index: "AssemblyCost", width: 50, align: "left", formatter: "currency", editable: true }, 
     { name: "AssemblyOrder", index: "AssemblyOrder", width: 50, align: "left", editable: true }, 
     { name: "AddToBudgetReport", index: "AddToBudgetReport", width: 100, align: "center", formatter: "checkbox", editable: true, edittype: 'checkbox' }, 
     { name: "AddToPartnerRequest", index: "AddToPartnerRequest", width: 100, align: "center", formatter: "checkbox", editable: true, edittype: 'checkbox' }, 
     { name: "Show", index: "Show", width: 50, align: "center", formatter: "checkbox", editable: true, edittype: 'checkbox'}], 

     // Grid total width and height and formatting 
     //width: 650, 
     //height: 220, 
     altrows: true, 

     // Paging 
     //toppager: true, 
     pager: $("#jqTablePager"), 
     rowNum: 10, 
     rowList: [10, 20, 30], 
     viewrecords: true, // Specify if "total number of records" is displayed 
     emptyrecords: 'No records to display', 

     // Default sorting 
     sortname: "AssemblyID", 
     sortorder: "asc", 

     // Grid caption 
     caption: "Build Template", 

     // grid command functionality 
     editurl: '@Url.Action("_AjaxUpdate")', 
     onSelectRow: function (AssemblyID) { 
      if (AssemblyID && AssemblyID !== lastsel) { 
       $('#jqTable').jqGrid('restoreRow', lastsel); 
       var cm = $("#jqTable").jqGrid('getColProp', 'AssemblyTypeName'); 
       cm.editable = false; 
       $("#jqTable").jqGrid('editRow', AssemblyID, true); 
       cm.editable = true; 
       lastsel = AssemblyID; 
      } 
     } 
    }).navGrid("#jqTablePager", 
     { refresh: false, add: true, edit: false, del: false }, 
      {}, // settings for edit 
      {}, // settings for add 
      {}, // settings for delete 
      {sopt: ["cn"]} // Search options. Some options can be set on column level 
    );

感謝您的幫助和耐心。
