1. Data binding, style and event binding, and the use of if else
```
<view class="usermotto" bindtap='clickMe'>
<text class="user-motto">{{motto}}</text>
<text wx:if="{{isShow}}">show</text>
<text wx:else>aaaa</text>
```
Can not use else
for loop
```
<view wx:for="{{rund}}" wx:for-item="item" wx:key="idx">
<text>{{item}}</text>
</view>
```
3. The interface jump has a return key.
```
onTap:function(){
wx:navigateTo({
.url:"../../pageTeo",
success:function(){
}
})
}
//replace without return key
onTap:function(){
wx:redirectTo({
.url:"../../pageTeo"
})
}
Bubbling event: Click the event of the child element The event of the parent element will also respond to
bindtap bubbling
catchtap non-bubbling
4: Import data
```
var data = require('./data.js')
module.export=data
```
5; use the template file template to have styles and xml
``` <template name='a'> <view>...</view> </template> 应用：xml <import src="template/template.xml"/> <template is="a"/> ```
