element-ui el-select下拉框 获取值

1、给el-select绑定change事件：

<el-select v-model="currentRoleId" @change="getSelectValue">
            <el-option label="请选择" :value="-1"></el-option>
            <el-option v-for="(item, i) in roles" :key="i" :label="item.rolename" :value="item.id"
            ></el-option>
</el-select>

2、在methods中获取值：

getSelectValue(id) { let obj = {}; obj = this.roles.find((item) => { return item.id === id; }); this.currentRoleName = obj.rolename; },
