Execute JavaScript Fuction Inside WebView Source

In React Native, you can call a JavaScript function inside a WebView using the injectJavaScript method or the injectedJavaScript prop from react-native-webview.

1. Using injectJavaScript Method

• The injectJavaScript method is used to execute JavaScript after the WebView has loaded.
• In the following example a button press triggers injectJavaScript, calling myJSFunction inside the WebView.

2. Using injectedJavaScript Prop

• The injectedJavaScript prop executes JavaScript when the WebView initially loads.
• When the WebView loads, injectedJavaScript runs automatically.
