React Native WebView Disable Touch - Javascript

React Native provides a WebView component that allows you to render web content within your React Native application. By default, the WebView component allows users to interact with the web content by touching the screen. However, in some cases, you may want to disable touch events within the WebView component to prevent user interaction.

To disable touch events within the WebView component in React Native, you can use the onShouldStartLoadWithRequest prop along with the scalePageToFit prop. Here's an example:

import React, { useState } from 'react';
import { View, Dimensions, WebView } from 'react-native';

const WebViewComponent = () => {
  const [disableTouch, setDisableTouch] = useState(false);

  const handleShouldStartLoadWithRequest = (request) => {
    return !disableTouch;
  };

  return (
    <View style={{ flex: 1 }}>
      <WebView
        source={{ uri: 'https://example.com' }}
        onShouldStartLoadWithRequest={handleShouldStartLoadWithRequest}
        scalesPageToFit={!disableTouch}
      />
    </View>
  );
};

export default WebViewComponent;

In the above example, we are using the WebView component from react-native library. We have a state variable disableTouch that determines whether touch events should be disabled or not. The handleShouldStartLoadWithRequest function is used as a callback for the onShouldStartLoadWithRequest prop. It returns true if touch events are enabled, and false otherwise.

The scalesPageToFit prop is set to !disableTouch to maintain the original behavior of the WebView. When disableTouch is false, the user can interact with the web content, and when disableTouch is true, touch events are disabled.

By dynamically updating the disableTouch state variable, you can enable or disable touch events within the WebView component based on your application logic.

Please note that the above code is just a sample and you may need to adjust it to fit your specific use case.
