jQuery的克隆选择不保留价值 [英] jquery clone select doesnt keep value

问题描述

我试图克隆一个小集，然后提交输入内容并使用序列化进行选择.它工作正常，但是select不能保持其价值.我尝试了几种发现的方法，但是似乎没有任何效果.这是我克隆和设置当前数据的方式.

I am trying to clone a feildset then submit the contents of inputs and selects using serialize. It is working properly however select doesn't keep its value. I have tried several methods I have found but nothing seems to work. Here is how I am cloning and setting the current data.

克隆时如何保持select的值?

How can I keep the value of select when cloning?

 $('body').append('<form id="form-to-submit" style="visibility:hidden;"></form>');  
var fieldsetName = $this.parents('.fieldsetwrapper');  
$('#form-to-submit').html($(fieldsetName).clone());  
var data = $('#form-to-submit').serialize();  

推荐答案

option元素通过selected javascript属性保持当前的选择(不要与selected属性混淆，该属性对应于默认选择).

The option element maintains its current selectedness with the selected javascript property (not to be confused with the selected attribute, which corresponds to default selectedness).

由于jQuery的clone不会克隆当前所选内容( http://bugs.jquery.com/ticket/1294 )，则必须手动进行:

Since jQuery's clone doesn't clone the current selectedness (http://bugs.jquery.com/ticket/1294) , you'll have to do it manually:

$('#form-to-submit').html($(fieldsetName).clone());
$('#form-to-submit select').val($('.fieldsetwrapper select').val());
