简单的 jQuery / javascript 方法来为正则表达式转义字符串中的特殊字符

Simple jQuery / javascript method to escape special characters in string for regexp

提问by John Hunt

I'm performing a regular expression using the match() method on a string that comes from the user and could contain anything, including $^'s etc.. so I need to escape those characters before this happens.

我正在使用 match() 方法对来自用户的字符串执行正则表达式，并且可以包含任何内容，包括 $^'s 等。所以我需要在发生这种情况之前转义这些字符。

Is there a common function in jQuery to do this, a well known javascript function or am I going to have to do it manually (with the chance I might miss something?)

jQuery 中是否有一个通用函数来执行此操作，一个众所周知的 javascript 函数，或者我将不得不手动执行此操作（我可能会错过某些内容？）

Found a function here:

在这里找到了一个函数：

RegExp.escape = function(text) {
    return text.replace(/[-[\]{}()*+?.,\^$|#\s]/g, "\$&");
}
