// Textarea and select clone() bug workaround | Spencer Tipping
|
|
// Licensed under the terms of the MIT source code license
|
|
|
|
// Motivation.
|
|
// jQuery's clone() method works in most cases, but it fails to copy the value of textareas and select elements. This patch replaces jQuery's clone() method with a wrapper that fills in the
|
|
// values after the fact.
|
|
|
|
// An interesting error case submitted by Piotr Przybył: If two <select> options had the same value, the clone() method would select the wrong one in the cloned box. The fix, suggested by Piotr
|
|
// and implemented here, is to use the selectedIndex property on the <select> box itself rather than relying on jQuery's value-based val().
|

(function (original) {
|
|
jQuery.fn.clone = function () {
|
|
var result = original.apply(this, arguments),
|
|
my_textareas = this.find('textarea').add(this.filter('textarea')),
|
|
result_textareas = result.find('textarea').add(this.filter('textarea')),
|
|
my_selects = this.find('select').add(this.filter('select')),
|
|
result_selects = result.find('select').add(this.filter('select'));
|
|
|
|
for (var i = 0, l = my_textareas.length; i < l; ++i) $(result_textareas[i]).val($(my_textareas[i]).val());
|
|
for (var i = 0, l = my_selects.length; i < l; ++i) result_selects[i].selectedIndex = my_selects[i].selectedIndex;
|
|
|

return result;
