Cascader 級聯選擇器沒法賦值

問題:

 1 html:
 2     <el-cascader
 3                 v-model="addform.qxvalue"
 4                 :options="options"
 5                 :props="defaultParams"
 6                 :show-all-levels="false"
 7                 placeholder="請選擇數據權限"
 8                 clearable></el-cascader>
 9 // 對應js:
10 // 設置默認
11     defaultParams: {
12         value: 'id',
13         label: 'name',
14         children: 'children',
15         multiple: true //能夠多選
16     }
17
18 此時賦值的時候出現沒法賦值的狀況

解決方法:

經過後臺拿到數組若是爲對象,須要轉換爲數組;
若爲數組則無需裝換;
由於該選擇器爲多選 因此數組嵌套數組(建議使用for in 遍歷)

只需拼接爲格式便可賦值,bug也能夠順利解決
