RN开发-Navigator
1、在入口组件render方法中返回<Navigator>
let defaultName = 'Welcome';
let defaultCompenent = Welcome;
<Navigator
initialRoute={{name:defaultName,component:defaultCompenent}}
/*configureScene={
(route) => {
//页面转跳动画 node_modules/react-native/Libraries/CustomComponent/navigate/
return Navigator.SceneConfig.VerticalDownSwipeJump;
}
}*/
renderScene={
(route,navigator)=>{
let Component = route.component;
return <Component {...route.params} navigator={navigator}></Component>;
}
}
/>
2、在Welcom组件的点击事件中修改转跳页面信息并添加参数
pressButton(){
const {navigator} = this.props;
const self = this;
/* 上文中,<Component {...route.params} navigator={navigator} 中传递了navigator作为props */
if(navigator){
navigator.push({
name: 'Detail',
component: Detail,
params:{
author:this.state.author,
user:this.props.user,
getResult: function(res){
self.setState({
result:res
})
}
}
})
}
}
3、在Detail组件中携带参数返回
(1)、接收参数
//生命周期方法
componentDidMount(){
this.setState({
author:this.props.author,
user:this.props.user
});
}
(2)、携带参数返回
backButton(){
const {navigator} = this.props;
if(this.props.getResult){
let result = USER_MODELS[1];
this.props.getResult(result);
}
if(navigator){
// 入栈出栈,把当前页面pop掉
navigator.pop();
}
}
