就按一般的RN组件传参方式就可以了,入参使用属性传入,返回参数使用回调函数传出,例:
this.navigator.push({view: <TestPage title='Test' onSubmit={value => this.onTestSubmit(value)}/>});
from teaset.
this.navigator.push({view: <AboutPage testDate={{data:{user:"user",name:"name"}}} />})
constructor(props) {
super(props);
console.log(this.props.testDate);
}
可以看到数据。
componentDidMount() {
this.interval = setInterval(() => {
this.setState({
timerCount: this._format(new Date())
})
}, 500)
}
componentWillUnmount() {
clearInterval(this.interval)
}
但是,模拟器放置一段时间后,报maximum call stack size exceeded
from teaset.
你在componentDidMount、componentWillUnmount加点日志看看这两个函数调用是不是成对出现,我记得从下层页面pop返回时会调用componentDidMount,但push时却不会调用componentWillUnmount,这样就会导致上一次的this.interval不会被clear,你加日志检查一下是不是这样
from teaset.
粗略的测试了一下,是成对出现,关于pop调用的问题,后续写代码的时候会留意。
目前的做法也是,
componentWillUnmount() {
this.interval&&clearInterval(this.interval)
}
也猜测了 this.interval
未声明的问题;
var a={} //Object {}
clearInterval(a.b) //undefined
目前未出现错误。
