推荐答案

Hello Krishna，



首先，你需要指明你的意思'特殊字符'在不同的场景中可以有所不同。至少，你应该提供一些例子和你想要的输出。



但是，通过一点猜测，我认为你试图拥有像'你的领域中有\[/＃

Hello Krishna,

To begin with, you need to specify what you mean by 'special characters' which can be different in different scenarios. At the very least, you should provide some examples and your desired output.

But, with a little bit of guessing, I think you are trying to have characters like '"\][/#

^！@。如果是这种情况，尽管使用JQuery很有可能你没有这样做的原因很简单，任何有一点知识的人都可以很容易地绕过它，你的网站很容易被黑客攻击。你要找的是'HTML编码/解码'。看一看在下面的链接/方法。



Server.HTMLEncode方法 [ ^ ]

C＃HtmlEncode，HtmlDecode [ ^ ]

HttpServerUtility.HtmlEncode方法（字符串） [ ^ ]



希望这会有所帮助，干杯

^!@ in your field. If this is the case, whilst this is quite possible using JQuery, you don't do that for the simple reason, anyone with a little bit of knowledge can bypass that very easily and your website will be hacked quite easily. What you are looking for is called 'HTML Encoding/Decoding'. Take a look at the below links/methods.

Server.HTMLEncode Method[^]
C# HtmlEncode, HtmlDecode[^]
HttpServerUtility.HtmlEncode Method (String)[^]

Hope this helps, Cheers
