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 } }) } })
