微信小程序wx:if中多条件判断

直接上代码：

<view wx:if="{
   
   {a}}">单个条件</view>
<view wx:if="{
   
   { !a }}">逻辑非</view>
<view wx:if="{
   
   {a || b}}">多个或条件</view>
<view wx:if="{
   
   {a && b}}">多个且条件</view>

<!-- wx:if else 的判断 -->
<view wx:if="{
   
   {a>1}}">1</view>
<view wx:elif="{
   
   {a < 1}}">0</view>
<view wx:else>5</view>
