亮点一、wx:if wx:else的使用来制作城市列表

1. <block wx:for="{{cityArray}}">
2. <block wx:if="{{item.type=='city'}}">
3. <view class="item" id="{{item.city}}" hover="true" hover-class="scroll-item-hover" bindtap="cityClickEvent">
4. <text class="city">{{item.city}}</text>
5. </view>
6. </block>
7. <block wx:else>
8. <view class="index" id="{{item.type}}">
9. <text class="city">{{item.type}}</text>
10. </view>
11. </block>
12. </block>

配套的城市代码（部分）：

1. cityArray: [
2. { "type": "A" },
3. { "city": "阿坝", "city_en": "Aba", "type": "city" },
4. { "city": "阿克苏", "city_en": "Akesu", "type": "city" },
5. { "city": "阿拉尔", "city_en": "Alaer", "type": "city" },
6. { "city": "阿勒泰",
