問題描述：
?當頁面搜索條件只有一個的情況下，輸入框不管有沒有值，回車后會跳轉頁面

解決辦法，給表單添加??@submit.prevent

      <el-form ref="ruleForm" :model="search" label-width="120px" class="form-class" @submit.prevent><el-row><el-col :span="6"><el-form-item :label="$t('包裝編碼:')" prop=""><el-input v-model="search.packingCode" class="input_class" /></el-form-item></el-col><el-col :span="18" class="btn_class"><el-button style="margin-left: 10px" type="primary" icon="search" @click="fniSearchTable">{{ '查詢' }}</el-button><el-button icon="refresh" type="primary" @click="handleResetSearch">{{ '重置' }}</el-button></el-col></el-row></el-form>
