简单的两表联查电影管理系统
下拉框回显代码
<el-form-item label="电影类型" prop="typeid">
<el-select v-model="userForm.typeid" placeholder="请选择角色姓名">
<el-option v-for="item in xialaData" :key="item.id" :label="item.typename" :value="item.id">
{{item.typename}}
</el-option>
</el-select>
</el-form-item>
下拉框的ajax请求的属性(数组)和方法
//下拉数据
xialaData: [],
//下拉列表
xiala() {
var that = this;
this.$http.get("/zz/type/list").then(function (resp) {
that.xialaData = resp.data.result;
console.log(resp)
})
},

//修改的方法

console.log(resp)

后台的两表联查的sql
<select id="select" resultType="com.zz.zz.entity.Movie">
SELECT m.*,t.Typename from tb_movie m join tb_type t
on m.Typeid=t.id
</select>
