循环标签:wx:for
<view wx:for="{{['aa','bb','cc']}}">
{{index}} {{item}}
</view>
这里的 index 和 item是微信默认的,可以自定义:
<view wx:for="{{['aa','bb','cc']}}" wx:for-index="a" wx:for-item="x">
{{a}} {{x}}
</view>
可以这样玩:点击删除
<view wx:for="{{color}}">
{{index}}:{{item}}
</view>
page.js文件
//获取应用实例
const app = getApp()
Page({
data: {
text: "点击",
onOff: false,
color: ['red','orange','yellow']
},
btnclick:function(){
var onOff = this.data.onOff;
var color = this.data.color;
color.shift();
this.setData({text:"新内容",onOff:!onOff,color:color});
}
})
