Question

原谅大块的代码，但我被困住了，并且真的被烧毁......

所以我正在加载一些内容，然后显示一个Dialog。根据你按哪个按钮我做了几件事。我的不一致似乎是在“保存计划”和“取消发送”块之间

这两个块中的代码相同

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，在取消发送块中，id未定义，因此拆分正在爆炸。

谁能告诉我，我做错了什么？

尝试使用$(table).find替换下面的table.find（因为您已经宣布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});
                         });

此外，如果您尝试从tr中选择每个$("#tblSchedule")，$("#tblSchedule").find("tr")可能是更好的选择器。

jQuery id在一个块中未定义但不在另一个块中？
