怎么把字符串内容已“，”分开？

把字符串从，分开，将两部分填入两个不同的框内
数组如下dsfNum: "JK-201404191020910000015,JK-201404191020910000015OIL"
希望达到
dsfNum1 =JK-201404191020910000015
dsfNum2 =JK-201404191020910000015OIL

let dsfNum= "JK-201404191020910000015,JK-201404191020910000015OIL";
    let a = dsfNum.split(",");
    console.log(a);// ['JK-201404191020910000015', 'JK-201404191020910000015OIL']
    console.log(a[0]);//JK-201404191020910000015
    console.log(a[1]);//JK-201404191020910000015OIL

上面的代码就可以解决啦，已经验证过了

字符串有split方法

let str = "dhjds,dsgbviu"
let a = str.split(',')[0]//console.log(a) >>dhjds

 let dsfNum="JK-201404191020910000015,JK-201404191020910000015OIL";
    let sdfArr=dsfNum.split(",");
    let obj={};
    sdfArr.map((item,index)=>{
      obj[`dsfNum${index+1}`]=item;
    });
    console.log(obj)

用正则表达式会简单点

let dsfNum = "JK-201404191020910000015,JK-201404191020910000015OIL"
let dsf = dsfNum.split(",")
let dsfNum1 = dsf[0]
let dsfNum2 = dsf[1]
