el-menu 菜单递归遍历找满足某个条件的值

数据结构是这样子的

params: [
                {
                    id: 1,      
                    label: '标签1',
                    children: [{
                        id: 4,
                        label: 'aaa',
                        children: [{
                            id: 9,
                            label: 'bbb',
                            rects: [
                                {
                                    
                                    minh: 300,
                                    minw: 300,
                                    
                                },
                                {
                                    
                                    minh: 300,
                                    minw: 300,
                                    
                                }
                            ],

                        }, {
                            id: 10,
                            label: 'ccc'
                        }]
                    }]
                }, 
                {
                    id: 2,
                    label: '标签2',
                    children: [{
                        id: 5,
                        label: '二级 2-1'
                    }, {
                        id: 6,
                        label: '二级 2-2'
                    }]
                }
            ],

寻找id 为 9 的叶子节点，并返回其rects的值

    searchId(index, obj) {
          if(obj instanceof Array){
                for(var i in obj) {
                    if(obj[i].children) {
                        this.searchId(index, obj[i].children);
                    } else {
                        if(obj[i].id.toString() === index) {
                            this.customParams = obj[i].rects;
                            return 
                        }
                    }
                }
            } else {
                if(obj.id.toString() === index) {
                    return obj[i].rects;
                }
            }
            
        },

template部分是这样子的

<el-menu 
            ref="healthMenu"
            :default-active="defaultActive"
            class="el-menu-vertical-demo"
            @open="handleOpen"
            @close="handleClose"
            background-color="#2A2A2A"
            text-color="#8A8A8A"
            active-text-color="#FFFFFF"
            :default-openeds="defaultOpeneds"
            @select="selectItems">
                <MenuTree :menuData="treeData"></MenuTree>
            </el-menu>
