1.在字符串提取数字

let str = “49-79”;
let arr = [ ];
var ret = str.replace(/[0-9](.[0-9])?/g, function(e) {
arr.push(e)
});
结果：arr = [49 , ‘ ‘ , 79 , ‘ ‘]

2.改造数据结构

  1. 将数组中的数据一个一个拿出来，由自己想要的形式组装。<br />    let len = this.price1.length<br />     for (let i = 0; i <= len; i++) {<br />         let min = this.price1[i].min<br />         let max = this.price1[i].max<br />         this.pricelist.push({<br />       'id': i,<br />       'name': min + '-' + max<br />         })<br />     }<br />     console.log(this.pricelist)
