在某些字符之前和之后添加字符串中的空格 [英] Add space in the string before and after certain characters

问题描述

我想在某些字符之前和之后在字符串中添加空格。

I want to add space in the string before and after certain characters.

var x = "asdasdasdasd+adasdasdasd/asdasdasdasd*asdasdasd-asdasdasd:asdasdasdadasdasd?";

我想在之前和之后添加空格

I want to add space before and after

var separators = ['+', '-', '(', ')', '*', '/', ':', '?'];

所以输出就像

asdasdasdasd + adasdasdasd / asdasdasdasd * asdasdasd - as ( dasd ) asd : asdasdasdadasdasd ?

推荐答案

您可以使用正则表达式。

You can use a Regex for that.

for (var i = 0; i < separators.length; i++) { 
      var rg = new RegExp("\\" + separators[i], "g"); 
      x = x.replace(rg, " " + separators[i] + " "); 
}
