替换后维护jQuery onChange [英] Maintain jQuery onChange After a Replacewith

问题描述

我有一些代码可以抓住页面上的第一个选择并对其进行克隆，以便以后可以根据需要将其重置.

I have some code that grabs the first select on the page and clones it so that I can reset it later on if needed.

mySelect = jQuery('select').get(0);
origSelect = jQuery(mySelect).clone();

jQuery(mySelect).change(function(){
   //some code
}

当我触发代码以重置选择时:

When I fire the code to reset the select with:

jQuery(mySelect).replaceWith(origSelect);

onChange函数停止工作.我已经确定是因为它现在被称为origSelect并响应该名称的onChanges.在这里，我是否有任何选项可以用origSelect的内容替换mySelect的内容，而无需更改其引用的名称?

The onChange function stops working. I've determined that it's because it is now referred to as origSelect and responds to onChanges for that name. Do I have any options here for replacing the content of mySelect with the content of origSelect without changing the name it's referred to by?

推荐答案

将参数true传递给克隆方法.

Pass a parameter true to the clone method.

origSelect = jQuery(mySelect).clone(true); //This will clone the select with data and events

或用mySelect替换origSelect的innerHTMl.

or replace the innerHTMl of origSelect with that of mySelect.

jQuery(origSelect).html(jQuery(mySelect).html());
