跳转页面时传参数：

encodeURIComponent 编码
decodeURIComponent 解码

如果是对象则先转json字符串

<view class="goodedList"><view class="list-items" v-for="(v,i) in dataList" :key="i"       
@click="handleDetails(`/pages/details/details?indexed=${encodeURIComponent(JSON.stringify(v))}`)"><view>{{v}}</view></view>
</view><script>export default {data() {},methods:{handleDetails(url){uni.navigateTo({url})},}}
</script>

进入详情后转回对象

<script>export default {data() {return {detailsObj: {}};},onLoad(e) {this.detailsObj= JSON.parse(decodeURIComponent(e.indexed))}}
</script>
