jQuery - 替换字符串中的所有括号

Question

I tried this:

mystring= mystring.replace(/"/g, "").replace(/'/g, "").replace("(", "").replace(")", "");

It works for all double and single quotes but for parentheses, this only replaces the first parenthesis in the string.

How can I make it work to replace all parentheses in the string using JavaScript? Or replace all special characters in a string?

Answer 1

Try the following:

mystring= mystring.replace(/"/g, "").replace(/'/g, "").replace(/\(|\)/g, "");

A little bit of REGEX to grab those pesky parentheses.

Answer 2

You should use something more like this:

mystring = mystring.replace(/["'()]/g,"");

The reason it wasn't working for the others is because you forgot the "global" argument (g)

note that [...] is a character class. anything between those brackets is replaced.

Answer 3

You should be able to do this in a single replace statement.

mystring = mystring.replace(/["'\(\)]/g, "");

If you're trying to replace all special characters you might want to use a pattern like this.

mystring = mystring.replace(/\W/g, "");

Which will replace any non-word character.

Answer 4

You can also use a regular experession if you're looking for parenthesis, you just need to escape them.

mystring = mystring.replace(/\(|\)/g, '');

This will remove all ( and ) in the entire string.

Answer 5

只需一个替换就可以：

"\"a(b)c'd{e}f[g]".replace(/[\(\)\[\]{}'"]/g,"")

Answer 6

这可以解决问题： myString = myString.replace(/\\"|\\'|\\(|\\)/) 示例

Answer 7

这应该工作：

mystring= mystring.replace(/"/g, "").replace(/'/g, "").replace(/\(/g, "").replace(/\)/g, "");

Answer 8

That's because to replace multiple occurrences you must use a regex as the search string where you are using a string literal. As you have found searching by strings will only replace the first occurrence.

Answer 9

The string-based replace method will not replace globally. As such, you probably want to use the regex-based replacing method. It should be noted:

You need to escape ( and ) as they are used for group matching:

mystring= mystring.replace(/"/g, "").replace(/'/g, "").replace(/\(/g, "").replace(/\)/g, "");
