我的主导航组件如下所示:
onTransitionedTo
我想在页面组件转换到导航器中时调用一个方法(类似 changeScene(data) {
if (this.refs.navigator.getCurrentRoutes().find(r => r.title === data.title))
this.refs.navigator.jumpTo(data);
else
this.refs.navigator.push(data);
this.setState({currentView: data.title});
if (data.component.onTransitionedTo)
data.component.onTransitionedTo();
}
)。我尝试了以下方法:

但这显然不起作用。什么是实现这一目标的最佳方式?

也许尝试在componentWillMount或其他一些适当的生命周期方法上执行传递的回调,以便组件检查它是否已转换到,而不是直接尝试在子项上执行某些操作的父组件。

plugin:
- name: "coverage"
jar: "coverage-1.3.5.jar"
module: "com.google.jstestdriver.coverage.CoverageModule"
在组件中:
React.createElement(PageOne, { isActive: () => this._isActive(PageOne) })
...
_isActive(component) {
let routes = this.refs.navigator.getCurrentRoutes();
return component === routes[routes.length - 1];
}
