推荐答案

首先要问自己的问题是为什么你需要这个。


很少这是个好主意。事实上，有些浏览器允许用户阻止JavaScript代码本身阻止某些预期的浏览器功能。

The first question to ask yourself is why you need this.

Rarely is it a good idea. In fact, some browsers allow users to prevent JavaScript code itself from preventing certain expected browser functionality.

我需要这个，因为我们正在使用电子邮件选项，所以我希望用户输入电子邮件ID。他们不应该复制/粘贴id'，他们应该只键入它。因此我应该解决这个问题!!


任何想法???

人类打字大大增加了错误的机会。

表单需要更长时间才能填写。

这些类型的限制可以使残障用户无法访问该页面。

这样做也会激怒普通用户。

它也没有惩罚那些有javascript禁用的人，有多公平是吗？


脚本中的内容会阻止< shift> +< insert>还是粘贴菜单键？


i求你先问问自己为什么要走这条路。

点击''提交''可以创建具有法律约束力的合同。


没有足够的理由这样做。

human typing vastly increases the chance for error.
the form take longer to fill out.
these types of restrictions can make the page less accessible to disabled users.
doing so will also anger a large chuck of regular users.
it also does nothing to penalize someone who has javascript disabled, how fair is that?

what in your script prevents <shift>+<insert> or a menu key from pasting it in?

i beg you to ask yourself why you are going down this path in the first place.
clicking ''submit'' can create a legally binding contract.

there is not a good enough reason to do so.
