求大神瞄一眼,关于block循环的一个问题(代码,日志,效果图都有)
wxml代码
< view class = 'xztz-items' > < scroll-view class = 'scroll-H' scroll-x = "true" style = 'width:100%' > < block wx:for = '{{items}}' wx:for-index = 'index' wx:for-item = 'item' > < view class = 'yuan' hover-class = 'yuan-hover' > < view class = 'yuan-1' >{{item.top}}</ view > < view class = 'yuan-2' >{{item.center}}</ view > < view class = 'yuan-3' >{{item.deep}}</ view > </ view > </ block > </ scroll-view > < text class = 'xztz-other iconfont icon-jiahao' bindtap = 'onPush' ></ text > </ view > |
items:[{ top: '(1)' , center: 'A' , deep: '护理' }, { top: '(2)' , center: 'B' , deep: '护理' }, { top: '(3)' , center: 'C' , deep: '护理' },] }, |
js代码
onPush: function (){ let obj = { top: '(4)' , center: 'D' , deep: '测试' } this .data.items.push(obj) console.log( 'items' , this .data.items) } |
我想实现的功能就是,点击一下加号
就往数组里push一个数据
然后触发block去加载
但是我的数据已经push进去了
但是block还是使用的push之前的数据
我怎么触发block去重新加载新数组里的数据呢???
请大神赐教,不胜感激
