vue 与小程序 中 给style与class 绑定值的区别

vue

:class="{active2: actionSheetHidden || showtankuang || showhaibao}"
 :class="['Detailactive2',{Detailactive:currentDetail==1}]"
:src="baseURL+'/weixinpl/shopping-temp/images/default.jpg'"
:style="{backgroundImage: 'url('+baseURL+'/weixinpl/shopping-temp/images/couppon.png)'}"
:style="{ height:data.img_list.length <= data.column ? '150upx' : '330upx', marginTop:data.margin+'px',marginBottom: data.margin2+'px' }"

小程序

 class="{{showtankuang||showhaibao||actionSheetHidden?'active2':''}}"
class="{{currentDetail==1?'Detailactive':''}} Detailactive2"
 style=" background-image: url('{{imgSrc}}')"
