1.点击事件<a data-current="{{setting.current}}" bindtap="clickcurrent" style="color:{{currentSelect.key == ‘current‘?mainColor:oldcolor}};"> <text>本期试用</text> <text class="activeline" style="background-color:{{currentSelect.key == ‘current‘?mainColor:whiteColor}};"></text> </a> bindtap="clickcurrent"
2.style的使用
style="color:{{currentSelect.key == 'current'?mainColor:oldcolor}};"
3.传值
data-current="{{setting.current}}"
如何获取
传过来event ,然后写event.currentTarget.dataset.current
4.wx:if的动态使用
wx:if="{{currentSelect.key == 'current'}}"
5.循环的使用,默认item和index.
<view class="fishqcTrycurrentProduct" wx:for="{{tryarray}}" wx:if="{{havacurrentdata}}" wx:key="{{item.id}}">
怎么样去修改变量名?
<view wx:for="{{array}}" wx:for-index="idx" wx:for-item="itemName">
{{idx}}: {{itemName.message}}
</view>
