element split 将多个单号分隔

const condeid = this.formData.WayBillCode;
var item = "";
const codes = condeid.split(",");

for (var i = 0; i < codes.length; i++) {
if (i + 1 === codes.length) {
item += "'" + codes[i] + "'";
} else {
item += "'" + codes[i] + "',";
}
}

 const valList = val.split(/,|，|、|s/);              //可以分割多种；
