    下拉列表想要获取其他表单明细表某一控件值作为选项，可以通过远程API传参进行查询对应表单里的子表单某一字段的值，再进行遍历赋值给数字，最后赋值给下拉列表。

    1.  /**
    2. * textField onChange
    3. * @param value 当前值
    4. */
    5. export function onChange({ value }) {
    6.   console.log('onChange', value);
    7.   let newValue = this.$('textField_ktmeifkf').getValue()
    8.   const params = {
    9.     formUuid: "FORM-UP966371AHVT49PR25S1G9BEMGI3264SCNXTK51",
    10.     searchFieldJson: JSON.stringify({
    11.       "textField_ktmc7w3h": newValue
    12.     })
    13.   }
    14.   this.dataSourceMap.getSelect.load(params).then((response) => {
    15.     // console.log(response.data)
    16.     let data = response.data[0].formData.tableField_ktmc7w3m;
    17.     console.log(data)
    18.     let arr = [];
    19.     data.map((item) => {
    20.       console.log(item.textField_ktmc7w3o);
    21.       arr.push({ "text": item.textField_ktmc7w3o, "value": item.textField_ktmc7w3o })
    22.     })
    23.     // console.log(arr)
    24.     this.$('selectField_ktmeifkg').set("dataSource", arr)
    25.   })
    26. }
