不知道字符串a是不是按照某种格式,如果是有固定格式的话
var a = "2, 3, 4, 5, 6, 7, 11, 22, 33, 44";
// convert to array
const numbers = a.split(", ");// split by ', '
// implement your logic
const include2 = numbers.find(number => number == 2);
const include1 = numbers.find(number => number == 1);
然后把这两个变量写成computed或者methods里,放到vue模版就可以了
