An interface implemented by a webview if it supports opening popups. For detailed examples, please see 3D WebView's PopupDemo and CanvasPopupDemo scenes.
There are several approaches that a web page can use to open a URL in a popup. For example, it can load a new URL using the window.open() JavaScript API or use the target="_blank" attribute on a link. In a normal web browser, these approaches cause the browser to open the new URL in a new tab or window. In 3D WebView, the default behavior is to load the new URL in the existing webview without creating a new webview. However, an application can change this by using the IWithPopups interface to make popup URLs open in a new popup webview.
await webViewPrefab.WaitUntilInitialized;
var webViewWithPopups = webViewPrefab.WebView as IWithPopups;
if (webViewWithPopups != null) {
webViewWithPopups.SetPopupMode(PopupMode.LoadInNewWebView);
webViewWithPopups.PopupRequested += async (sender, eventArgs) => {
Debug.Log("Popup opened with URL: " + eventArgs.Url);
// Create and display a new WebViewPrefab for the popup.
var popupPrefab = WebViewPrefab.Instantiate(eventArgs.WebView);
popupPrefab.transform.parent = transform;
popupPrefab.transform.localPosition = Vector3.zero;
popupPrefab.transform.localEulerAngles = new Vector3(0, 180, 0);
await popupPrefab.WaitUntilInitialized();
popupPrefab.WebView.CloseRequested += (popupWebView, closeEventArgs) => {
Debug.Log("Closing the popup");
popupPrefab.Destroy();
};
};
} EventHandler<PopupRequestedEventArgs> PopupRequested Indicates that the webview requested a popup.
