<view class="box"><text>日期:</text><view class="date">{{obtaindate}}</view></view>

wxml中定义了一个文本元素，通过{{obtaindate}}获取js页面传递的日期数据

data:{obtaindate:""
},
onload:function(){let date= new Date;let year = date.getfullYear();let mounth = date.getmounth();let day = date.getday();let obtaindate = "$year-$mounth-$day";this.setDate({obtaindate:obtaindate
});
},

js页面中定义了一个date，通过该对象获取年月日，并将其拼接起来，通过this.setDate方法将拼接好的日期写入页面中

运行结果如下
