有没有办法使用 webview.goBack 和 navigation.goBack 在 react native webview 中使用相同的按钮？

Question

I'm working on a react native app which uses a webview. I want to use a single back button to navigate within the webview as well as to exit the webview and return to the homescreen of the app. I'm aware of canGoBack property but the onNavigationStateChange function is fired only when navigating to a link in another domain. Any way i can can achieve the same functionality when navigating between screens in the same domain?

Answer 1

On same button click check

if (webview.goBack()){
  // if web view has something to go back use it
}else{
navigation.goBack()
}
