1。从生命周期回调中调用。 我有下面的代码:
// app.js
<Admin>
<Resource name="FooList" list={FooList} />
</Admin>
// FooList.js
class FooList extends React.Component {
componentDidMount () {
showNotification("foo")
}
}
export default connect(null, {showNotification})(FooList)
安装组件后,控制台出现错误:
Warning: React does not recognize the `showNotification` prop on a DOM element. If you intentionally want it to appear in the DOM as a custom attribute, spell it as lowercase `shownotification` instead. If you accidentally passed it from a parent component, remove it from the DOM element.
2。呼叫某个事件(例如,单击)。在其他情况下,我有一些处理程序,并在其中调用showNotification
。
class Foo extends React.component {
handleClick = () => {
showNotification('Hello, World')
}
}
export default connect(null, { showNotification })(Foo)
在这种情况下,将调用handleClick,但没有出现通知,但控制台中没有错误
同胞是我对项目的依赖

如何在react-admin应用程序中显示通知? 我错过了什么?

动作分派器作为属性传递到组件上,因此名为mapDispatchToProps
。因此,要调用动作分派器,您可以使用this.props.showNotification('Hello, World')
