我正在尝试从jQuery表中动态生成的单元格获取数据，但是始终有相同的问题，我的数据是“未定义的”。有人可以帮助我或提供任何建议吗？
我的代码：
function loadWeekData() {
// Append database data here
$.ajax({
type: "GET",
url: "/Home/JsonWeekEvents",
dataType: "JSON",
success: function (result) {
$.each(result, function (i, val) {
var trow = $('<tr/>').data("id", val.Id);
//trow.append('<td>' + val.Id + " " + '</td>');
trow.append('<td style="padding:5px; width:100px; height:70px"></td>');
trow.append('<td valign="top" style="padding:2px; width:150px; height:100px">' +
'<div class="ui-widget">' +
'<input size="10" maxlength="10" id="tagsM" class="tags" />' +
'<input type="button" id="addBtn" class="addEvent" size="5" value="+" /><br/>' +
'<div style="text-align:center" id="monVal" class="desc_Num">' + val.Monday + '</div >' +
'<input type="hidden" class="idEvent" />' +
'</div >' +
'</td>');
trow.append('<td valign="top" style="padding:2px; width:150px; height:100px">' +
'<div class="ui-widget">' +
'<input size="10" maxlength="10" id="tagsT" class="tags" />' +

[在最后一个“ tab.on”中，我试图从“星期一”单元格中获取数据，但是它始终是“未定义的...
有人有想法吗？
我只想获取全天的所有数据，然后通过Ajax“ POST”函数将其传递到数据库中。
您必须更改此行
var div = $(this).closest("div").find("monVal");
进入
var div = $(this).closest("div").find("#monVal");
因为您要查找的<div>具有id monval。
