append fails with HierarchyRequestError when cloned objects are cached and later appended

[ryanmch@…]

Scenario: Adding rows to a table by cloning the last row, resetting the input values and adding a change handler to each text input

Assumptions: Given a table defined in the DOM with id="tbl" The table has a minimum of one row defined with one text input in each of one or more cells

This works:

var tbl = $("#tbl")[0];

$(tbl).append($(tbl.rows[tbl.rows.length-1]).clone().find("input:text").val("").change(tableCellTextChanged).end());

This Fails:

var arr = [];

var tbl = $("#tbl")[0]; arr.push($(tbl.rows[tbl.rows.length-1]).clone().find("input:text").val("").change(tableCellTextChanged).end()); $(tbl).append(arr[0]); Throws HierarchyRequestError in the Clean function in JQuery

Using native JavaScript works though:

var arr = []; var tbl = $("#tbl")[0]; arr.push($(tbl.rows[tbl.rows.length-1]).clone().find("input:text").val("").change(tableCellTextChanged).end()[0]);

tbl.appendChild(arr[0]);

Please provide a test case in jsFiddle. Also, did you mean to append to the table TBODY? Rows don't under the table element.

Rows do append to the table object. Here is the URL for my jsfiddle test case. ​http://jsfiddle.net/ryanmch/W34SW/23/

I reduced your test case. ​http://jsfiddle.net/dmethvin/W34SW/30/

Try appending either an array of the DOM elements or a jQuery collection containing the DOM elements, but NOT a jQuery collection containing a jQuery collection with the DOM elements. For questions like this in the future, please ask for help on the forum.

This does not work using JQuery 1.7.2 though. That is the version I specified in the bug. Your fiddle was using the latest JQuery version.

I can't tell you what we fixed offhand, but if it works in the current version then that's the one I'd recommend. It does work in 1.8.3. We don't provide patches for old versions.
