我的寫法將score定義成一個(gè)自定義屬性，綁定；@changge綁定事件，相關(guān)代碼template代碼：        <!-- 職務(wù)級別 -->       <el-form-item label="學(xué)會職務(wù)級別" prop="academicLevel">         <el-select v-model="academicForm.academicLevel"          placeholder="請選擇職務(wù)級別"          @change="currentSel(index)">           <el-option v-for="(item, index) in academicRule"            :key="index"            :label="item.category"            :value="item.category"            :data-score="item.score">           </el-option>         </el-select>       </el-form-item>       <!-- 獎(jiǎng)項(xiàng)分?jǐn)?shù) -->       <el-form-item label="分?jǐn)?shù)" prop="academicScore" v-show="false">         <el-input v-model="academicForm.academicScore" placeholder="請輸入論文分?jǐn)?shù)">         </el-input>       </el-form-item>script 代碼methods: {     currentSel(index,value) {     console.log(academicRule[index]['score']);     this.academicForm.academicScore = this.academicForm.academicLevel;     },錯(cuò)誤報(bào)錯(cuò)：academicRule is not defined因?yàn)椋篴cademicRule是prop屬性的值，不知道如何改。。。求教
