使用js代码将一个值为“1=增量，2=全量“的字符串转化为一个数组，数据格式为[{value:““,label:“‘‘}]
const str = "1=增量，2=全量";
const arr = str.split(",").map(item => {const [value, label] = item.split("=");return { value, label};
});
const str = "1=增量，2=全量";
const arr = str.split(",").map(item => {const [value, label] = item.split("=");return { value, label};
});
