jQuery id在一个块中未定义，但不是另一个？

Question

原谅大块的代码，但我被卡住，真的被烧毁在这...

所以我加载一些内容，然后显示一个对话框。根据你按哪个按钮，我做了几件事。我inconsistancies似乎是保存计划之间和取消发送块

此代码是相同的两个块

var dt = $(this).find("input[type=text]").val(); 
var id = $(this).find("input[type=text]").attr("id"); 
var CustomObjectKey = id.split("_")[1]; 
var alt = $(this).find("input[type=text]").attr("alt"); 

然而，在取消发送块的ID是不确定的，因此，拆分吹起来。

任何人都可以告诉mw我做错了吗？

$("#ActionContainer").load(wsUrl, { Function:"BuildScheduleDialog", ArticleID:ArticleID}, function(){ 
       var Subject = $(this).find("#hdnSubject").val(); 
       $("#ActionContainer").dialog({ 
        title: "Edit Schedule: " + ArticleTitle, 
        height: 'auto', 
        width: 'auto',

        buttons: { 
         'Cancel': function() { 

          $(this).dialog('close'); 
         },

          var that = $(this); 
          var table = $("#tblSchedule"); 
          var parameterArray = []; 

          //loop each row of the Schedule table to get the parameters 
          $(table).find("tbody>tr").not(':first').each(function() {

尝试只用table.find低于更换$(table).find（因为你已经宣布table = $("#tblSchedule")

      var table = $("#tblSchedule"); 
         var parameterArray = []; 

         var status = ""; 
         $(table).find("tbody>tr").each(function() {          
          var dt = $(this).find("input[type=text]").val();          
          var id = $(this).find("input[type=text]").attr("id");          
          var CustomObjectKey = id.split("_")[1];          
          var alt = $(this).find("input[type=text]").attr("alt");                   
          parameterArray.push({Region: $(this).find("span").text(), Date: dt, ArticleTitle: ArticleTitle ,ArticleID: ArticleID, PublicationTypeID: PublicationTypeID, CustomObjectKey:CustomObjectKey}); 
         }); 

另外，如果你想选择每个tr从$("#tblSchedule")，$("#tblSchedule").find("tr")可能是更好的选择。
