uniapp vue 函数方法中的遍历数组方式

for 循环遍历

for (let i = 0; i < this.list.length; i++) {
    if (scrollTop > this.list[i].top && scrollTop < this.list[i].bottom) {
        this.verticalNavTop = (this.list[i].id - 1) * 50
	this.tabCur = this.list[i].id
	console.log(scrollTop)
	return false
    }
}

forEach 循环遍历

that.cates.forEach(item=>{
    if(item.length>0){
        item.child.forEach(child=>{
            if(item.id==pid && id==child.id){
                that.catename=child.name
                that.orderindex=child.orderindex
                that.cateid = chilid.id
            }
         })
    }
})
