如何在javascript中组合正则表达式？

This might be easy for those who play with regular expressions.

对于那些使用正则表达式的人来说,这可能很容易。

str = "Here is 'sample' test";
str = str .replace(new RegExp('"', 'g'), '');
str = str .replace(new RegExp("'", 'g'), '');

How to combine 2nd and 3rd line, I want to combine regular expressions new RegExp('"', 'g') and new RegExp("'", 'g') into one regular expression, this will make it in one line. Thanks in advance.

如何组合第2行和第3行,我想将正则表达式新的RegExp('“','g')和新的RegExp(”'“,'g')组合成一个正则表达式,这将使它在一行中。提前致谢。

6 个解决方案

#1

Try:

str = str.replace(new RegExp('["\']', 'g'), '');

#2

str = str.replace(/"|'/g, '')

#3

str.replace(/['"]+/g, '')

#4

You can simply use a character class for this, to match both single and double quotes you can use ['"].

你可以简单地使用一个字符类来匹配你可以使用['“]的单引号和双引号。

In a full regex you would need to escape one of the quotes though.

在一个完整的正则表达式,你需要逃脱其中一个引号。

var str = "here is 'sample' test";
str = str.replace(/["']/g, '');

Similar to Andrew's solution:

与Andrew的解决方案类似:

str.replace(/"|'/, 'g')

-1

str = "Here is 'sample' test".replace(new RegExp('"', 'g'), '').replace(new RegExp("'", 'g'), '');

An example that's basically the same as yours, except it uses method chaining.

一个与你的基本相同的例子,除了它使用方法链。
