React Native WebView onMessage doesn`t work
0
My companent
import React, {Component} from 'react';
import {WebView} from 'react-native';
class Html extends Component {
constructor(props){
super(props);
this.webView = null;
}
onMessage( event ) {
console.log( "On Message", event.nativeEvent.data );
}
sendPostMessage(msg) {
console.log( "Sending post message",msg );
this.webView.postMessage(JSON.stringify(msg));
}
runJSInBackground (code) {
this.webView.injectJavaScript(code)
}
render() {
return (
<WebView
originWhitelist={['*']}
ref={( webView ) => this.webView = webView}
onMessage={this.onMessage}
onError={(e)=>console.log("WebView error: "+e)}
source={{
baseUrl:"include/",
html: `
<html>
<head>
</head>
<body>
<script>
document.addEventListener("message",function(event) {
console.log("Received post message", event); //Work!!!
}, false);
setTimeout(()=>window.postMessage("WhatsAppMANNN!!!"),5000) //doesn`t work ((
</script>
</body>
</html>
` }}
/>
)
}
}
export default Html;
Everything works fine when I send a WebView request, but there is no answer to the return. That is, the window.postMessage method does not work, and the error does not light either. What's the catch, not how I can not find the answer to this question.

Does not help, tried and wait for the bridge function waitForBridge() { if (window.postMessage.length !== 1) setTimeout(waitForBridge, 200); else window.postMessage('abcccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc'); } window.onload = waitForBridge;

waiting for the bridge with window.postMessage.length === 1 does not work since chrome 70
