js如何把"[0.1,0.2)" 这样的字符串 处理成 "0.1-0.2"?

Answer 1

正则表达式：[[](.*),(.*)[)]

Answer 2

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

Answer 3

var str = '[0.1,0.2)';

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

Answer 4

开个脑洞答案：

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

Answer 5

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

Answer 6

Answer 7

先转成数组，然后调用join方法
