使用 jQuery 将行添加到表的 tbody

I am trying to add rows to the tbody of a table. But I am having issues with achieving that. Firstly, the function where everything takes place is called on change of a dropdown from a html page. I created a tr string containing all the td inside that containing the html elements, text and other stuff. But when I am trying to add that generated row to the table using:

$(newRowContent).appendTo("#tblEntAttributes tbody");

I am encountering an error. The name of the table is tblEntAttributes and I am trying to add it to the tbody.

Actually what's happening is jQuery is unable to get tblEntAttributes as an html element. But I can access it using documemt.getElementById("tblEntAttributes");

有没有办法通过在表的tbody行中添加行来实现这一点.也许是旁路什么的.

以下是完整的代码:

var newRowContent = "<tr><td><input type=\"checkbox\" id=\"" + chkboxId + "\" value=\"" + chkboxValue + "\"></td><td>" + displayName + "</td><td>" + logicalName + "</td><td>" + dataType + "</td><td><input type=\"checkbox\" id=\"chkAllPrimaryAttrs\" name=\"chkAllPrimaryAttrs\" value=\"chkAllPrimaryAttrs\"></td><td><input type=\"checkbox\" id=\"chkAllPrimaryAttrs\" name=\"chkAllPrimaryAttrs\" value=\"chkAllPrimaryAttrs\"></td></tr>";

$("#tblEntAttributes tbody").append(newRowContent); 

我忘记提到的一件事是，编写这段代码的函数实际上是ajax调用的成功回调函数.我可以使用document.getElementById("tblEntAttributes")访问该表，但由于某些原因$(#tblEntAttributes)似乎不起作用.
