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 算术出现索引 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);
