vue3.0中使用Element-Plus中Select下的filter-method属性代码示例

 <el-select
                  v-model="form.outTruckId"
                  placeholder=" "
                  filterable
                  clearable
                  :filter-method="outTruckinput"
                  @clear="outclear"
                  v-if="scope.row.action == 'edit'"
                >
                  <el-option
                    v-for="item in OutTruckOptionList"
                    :key="item.keyCode"
                    :label="item.valueCode"
                    :value="item.keyCode"
                  />
                </el-select>

// 获取下拉框的输入值
function outTruckinput(e) {
  // 自定义查询方法
  let list = ref();
  list.value = OutTruckOptionList.value;

  if (e) {
    OutTruckOptionList.value = list.value.filter((item) => {
      return item.valueCode.indexOf(e) > -1;
    });
  } else {
    //刷新下拉列表
    console.log("刷新下拉列表,重新给OutTruckOptionList.value赋值");
  }
}
