Due to the dynamic form filling line, so I used the append (text) function in jquery, beautiful layout for the code, which I joined in the appropriate spaces, and therefore lead to a tragedy.
$("#tableId").append(" <tr><td> </td></tr> ");
The above statement work properly in IE8, Chrome and other browsers, but not correct in IE6, click Add row is invalid, did not prompt an error.
Around in a big circle, I checked a lot of places, even jquery upgrade to the latest version can not solve the problem.
It was accidentally inside the code for the layout of spaces removed, a miracle just happened, problem solving, really pit father ah.
The correct code is:
$("#tableId").append("<tr><td> </td></tr>");
