使用@submit.native.prevent为el-form设置提交方法。
使用native-type为el-button设置原生按钮类型。
示例如下：
<el-form class="search" @submit.native.prevent="submitSearch"><div class='search-item'>人员ID :<el-input size='mini' v-model='search.id' placeholder='请输入人员ID' clearable></el-input></div><div class='search-item'>人员账号 :<el-input size='mini' v-model='search.loginName' placeholder='请输入人员账号' clearable></el-input></div><div class="search-item"><el-button size="mini" type="primary" @click="submitSearch" native-type="submit">查询</el-button></div>
</el-form>
