问题
- 安卓返回键
- 页面之间传参数
- Vue页面生命周期
vue.js实现
<template>
//页面根节点
<div @onAndroidBack="onAndroidBack" @ready="ready" @actived="actived" @deactived="deactived" class="container">
</div>
</template>
<script>
methods: {
//页面ready 页面传参
ready(param){
let p = JSON.stringify(e.param)
console.log('pageA页面传参数=' + p);
},
//页面激活 param 页面传参
actived(param){
},
//页面失活
deactived(){
},
//
onAndroidBack(){
uNavigator.pop();
},
onClick(){
uNavigator.popTo({index:-1,tagCode:"pageb",param:{test:'testB'}},() => {} );
}
},
