I’m trying to find the proper way to define some components which could be used in a generic way:
There is a logic going on for rendering between parent and children components of course, you can imagine
);
}
});
var Child = React.createClass({
onClick: function() {
this.props.doSomething(this.props.value); // doSomething is undefined
},
render: function() {
return (
);
}
});
The question is whenever you use {this.props.children} to define a wrapper component, how do you pass down some property to all its children?
React.Children allows you to iterate over the children to Cloning children with new props, and then clone each element (shallow merged) with a new app (see the code comment why I don\’t recommend this approach).\n\nParaphrase: The use of cloneElement is unusual and can lead to fragile code. See common examples: react.dev.\n\n\n\nConst Child = ( childName, sayHello ) => ( i.e., onClick=(child Name)>childName/button> ); .\n\nfunction Parent( children –) ‘ // We pass this ‘childchildName’ function. function sayhello(childname) – console.log (Holdello from $child Namethe child); .\n\nChild => // Checking isValidElement in const childrenWithProps = React.Children.map(children) and avoids a // typescript error too. if (React .isValineIlement) – return ReactedRec.cloneElelement (child, e.g. ( sayHello -); ‘ return child; ; ‘).\n\nReturn div>childrenWithProps/Div> .\n\nThis is a less type-safe and Typescript friendly approach: function App() // // It looks like you\’re trying to render \”Child\” without \”sayHello\”. // This approach also confuses readers of this code. return (Parent>,Chilld childName=\”Bob\” /> \”> \’/Pent] ).\n\nReactDOM.render(App />, document.getElementById((\”container\”)); script src=\”https://unpkg.com/react-backback@17/umd/detail.js\”>Script \’script-shrink-wraprap-to-brand-process-work-risk-control-trial-run-timetime-d> .\n\n\n\nAlternatively, you can pass props to children via render prop.’ The children (which can be children or any other prop name) can accept any arguments you want to pass and return the real children: .\n\nConst Child = ( childName, sayHello ) => ( i.e., onClick=(child Name)>childName/button> ); .\n\nA function Parent( children ) (function sayHello(childName)) – console.log(\’Hiello from $child Name the child); .\n\nParent\’s // children must be a function // which returns the real children. We can pass // it args and then pass them into them as props (in this // case we pass .\n\nThe arg we passed in Parent is function App() // sayHello, which // we pass through to Child. return (Parent>(sayHellell) => (advanced childName=hello \’Billy\’ sayBob\’ \”ChilD child Name=\”sayHob\” -/> ); .\n\nReactDOM.render(App />, document.getElementById((\”container\”)); script src=\”https://unpkg.com/react-backback@17/umd/detail.js\”>Script \’script-shrink-wraprap-to-brand-process-work-risk-control-trial-run-timetime-d> .
