1.問題如上，相關(guān)代碼：

<el-form ref="dynamicValidateForm" :model="dynamicValidateForm" label-suffix="" label-width="80px" label-position="left" >
    <el-row v-for="(demand, index) in dynamicValidateForm.demands">
        <el-col :span="4">
            <el-form-item :label="index+': 人員'" :key="demand.key" :prop="'demands.' + index + '.value1'"
                          :rules="{required: true, message: '人員不能為空', trigger: 'blur'}">
                <el-autocomplete class="inline-input" v-model="demand.value1" :fetch-suggestions="querySearch1" placeholder="請輸入人員需求" @select="handleSelect1"></el-autocomplete>
            </el-form-item>
        </el-col>
        <el-col :offset="1" :span="4">
            <el-form-item :label="'-語言'" :key="demand.key" :prop="'demands.' + index + '.value2'"
                          :rules="{required: false, message: '語言不能為空', trigger: 'blur'}">
                <el-autocomplete class="inline-input" v-model="demand.value2" :fetch-suggestions="querySearch2" placeholder="語言或技術(shù)要求" @select="handleSelect2"></el-autocomplete>
            </el-form-item>
        </el-col>
        <el-col :offset="1" :span="1">
            <el-button @click.prevent="removeDemand(demand)">刪除</el-button>
        </el-col>
    </el-row>
    <el-form-item>
        <el-button @click="addDemand">新增需求</el-button>
        <el-button @click="test">輸出測試</el-button>
    </el-form-item>
</el-form>
         

data區(qū)域：

data: {
        position: [
            { "value": "UI設(shè)計師"},
            { "value": "前端web開發(fā)"},
            { "value": "前端安卓開發(fā)"},
            { "value": "前端ios開發(fā)"},
            { "value": "后端開發(fā)"},
            { "value": "測試人員"}
        ],
        technical: [
            { "value": "c語言"},
            { "value": "c++語言"},
            { "value": "java語言"},
            { "value": "c#語言"},
            { "value": "python語言"},
            { "value": "php"},
            { "value": "java script"}
            ],
        dynamicValidateForm: {
            demands: [{
                value1: '',
                value2: ''
            }]
        }
    },   

2.這是一個帶有選擇建議的輸入框，手動輸入可以通過required驗證，但是選擇就無法通過，效果如下：

選擇后：

但是手動輸入就沒問題

怎么解決？
