如何使用其DOM元素创建表单的副本 [英] How to create a copy of a form with its DOM elements

问题描述

如何创建具有所有表单元素的表单副本，以便可以操纵该副本并且保持原样不变?

How does one create a copy of a form with all of its form elements so that the copy can be manipulated and the original is left unchanged?

推荐答案

像这样使用纯JavaScript cloneNode

Using plain javascript cloneNode like this

var dupNode = node.cloneNode(deep);

示例

var p = document.getElementById("para1"),
var p_prime = p.cloneNode(deep); 
//If "deep" is set to true it will clone all the child nodes too,
//If set to false then only the node and not the children

这是文档.
