Javascript IE6 / 7/8改变输入类型 [英] Javascript IE6/7/8 change input type

问题描述

以下javascript代码段将改变INPUT的类型，例如从文本到密码。它用于允许用户在输入密码时在屏幕上显示他们的密码：

The following javascript snippet will change the type of an INPUT, for instance from text to password. It's being used to allow users to display their password on-screen when typing it in:

document.save_form.password_confirm.type= 'text';
...
document.save_form.password_confirm.type= 'password';

这对FF / Chrome非常有用，但是在IE6 / 7/8中，我得到了This命令不受支持错误消息。

This works great in FF/Chrome but in IE6/7/8 I'm getting a "This command is not supported" error message.

推荐答案

类型在Internet Explorer中是只读的（至少6，无论如何），所以它不是直接可能的。作为一种解决方法，我有一个我想要的类型的隐藏输入字段，然后当我需要切换类型时，隐藏旧类型并使另一个类型可见。不是很干净，但不幸的是，只要改变类型，据我所知是不可能的。

Type is read-only in Internet Explorer (at least 6, anyway), so it's just not directly possible. As a workaround, I've had a hidden input field of the type I wanted, then when I need to switch the type, hid the old one and made the other one visible. Not as clean, but unfortunately just changing the type as far as I know isn't possible.

另一种方法是使用JavaScript DOM来替换字段节点的replaceChild功能。

An alternative method would be to use the JavaScript DOM to replace the field with the replaceChild function of a node.
