Question

愚弟新手,怎么把list:['001','002']转换成字符串 list:'001,002'谢谢

可以调用Array.join()方法。

直接['001','002']+''
或是调toString()方法

或者['001','002'].join(',')

Answer 4

`let arr = "list:['001','002']";
console.log(arr.toString());
let pattern = /[[]]/g;
console.log(arr.toString().replace(pattern,''));
console.log(arr.toString().match(/<sup>1</sup>/g).join(''));`
