Taro+react开发（54) 数组转字符串join

    value.map((item, index) => {
      arr.push({ industryCode: item });
    });

    console.log(arr, "arr1111");
    console.log(arrcode, "111arr1111");
    console.log(arrcodeList, "arrcodeList");
    console.log(value.join("-"), "join");
    this.setState({
      industrySel: arrcodeList.join("-"),
      industryCodeArr: arr,
      industryCodeList: value
    });
