[Vue warn]:Missing required prop: “value” error solution

.Error scene

Using the el-select tag of element-ui in vue reports an error

[Vue warn]: Missing required prop: "value"

 

 

 .The cause of the problem

     1. The el-select tag does not use the v-model binding value

<--  没有绑定v-model -->
<el-select class="status" @change="handleFilter">
     <el-option v-for="i in [1, 2, 3]" :key="i" :label="i" :value="i"></el-option>
 </el-select>

    2. el-option does not perform value assignment

<-- el-option没有进行value赋值 -->
<el-select v-model="query.status" class="status" @change="handleFilter">
   <el-option v-for="i in [1, 2, 3]" :key="i" :label="i"></el-option>
 </el-select>

    3. None of the above are bound

.Solve the problem

Just add v-model to el-select tag and value to el-option

<el-select v-model="query.status" class="status" @change="handleFilter">
   <el-option v-for="i in [1, 2, 3]" :key="i" :label="i" :value="i"></el-option>
 </el-select>
