javascript - How to replace “ &ldquo with double quotes?

Question

I would like to do something like this:

 s = s.replace(/(”)/g, '"'); // need to replace with double quotes
 s = s.replace(/(“)/g, '"'); // need to replace with double quotes
 s = s.replace(/(’)/g, "'"); // need to replace with single quotes

But for me this does not work. I tried all the ways.

Answer 1

您可以在替换中使用 Unicode 值：

s = s.replace(/\u201C|\u201D/g, '"');  // for “ or ”
s = s.replace(/\u2019/g, "'");         // for ’

Answer 2

所以我们打开控制台，看看：

>>> 'test&rqduo;foo'.replace(/&rqduo;/g, '\"' );
test"foo

并带大括号：

>>> 'test&rqduo;foo'.replace(/(&rqduo;)/g, '\"' );
test"foo

一切都如你所想。请检查您的输入字符串。
