【微信小程序】mpvue中页面之间传值（全网唯一真正可行的方法，中指推了一下隐形眼镜）...

<script>
var that &＃61; null;
export default {data () {return {setData: function (key,value) {that[key] &＃61; value}}},
}
<script>

1 getBrand (brand) {
2 let { from } &＃61; this.$root.$mp.query
3 let pages &＃61; getCurrentPages()
4 let page &＃61; pages.find( item &＃61;> item.route.indexOf(from) !&＃61; -1)
5 page.data.$root[0].setData(&＃39;brand&＃39;,brand)
6 wx.navigateBack({
7 delta: 1
8 });
9 }
