在每次出现算术运算符时拆分一个字符串 [英] Split a string at every occurrence of arithmetic operator

问题描述

我有以下变数

var arithmetic = "96-66.33+99.3/22*58.2";
var arr;
var operator = "/*+-^";

我想拆分 算术每出现或索引 运算符变量。

最终结果将是 [96， - 66.33，+ 99.3，/ 22，* 58.2];

V.Roudge提供的最终解决方案

var arithmetic = "96-66.33+99.3/22*58.2";
arithmetic = arithmetic.split(/(?=[-+*\/])/);
console.log(arithmetic);

推荐答案

最近我可以通过正则表达式。非常接近，但现在还不是。

Closest I could get you through regexp. Very close but not it exactly yet.

var arithmetic = "96-66.33+99.3/22*58.2";
arithmetic = arithmetic.split(/([-+*\/])/g);
console.log(arithmetic);

编辑：知道了。

var arithmetic = "96-66.33+99.3/22*58.2";
arithmetic = arithmetic.split(/(?=[-+*\/])/);
console.log(arithmetic);

var arithmetic = "96-66.33+99.3/22*58.2";
arithmetic = arithmetic.split(/(?=[-+*\/])/);
console.log(arithmetic);
