js如何把"[0.1,0.2)" 這樣的字符串 處理成 "0.1-0.2"?

const reg = /(?:[|()(.),(.)(?:]|))/g
str.replace(reg, '$1-$2')

let str = "[0.1,0.2)";
let newStr = str.substring(1,str.length-1);
console.log(newStr.split(',').join('-'));

var str = '[0.1,0.2)';

var reg = /\[(\d\.\d),(\d\.\d)\)/;
console.log(str.replace(reg,'$1-$2'));

先轉(zhuǎn)成數(shù)組，然后調(diào)用join方法

開(kāi)個(gè)腦洞答案：

JSON.parse("[0.1,0.2)".replace(/\(/g, '[').replace(/\)/g, ']')).join('-')

正則表達(dá)式：[[](.*),(.*)[)]
