iOS Cordova应用中使用window.open()打开PDF时能否启用旋转？

Yep, this is totally possible—but you can’t rely on just the window.open parameters to make it happen. Since your app has global rotation disabled, you’ll need to use a Cordova plugin to dynamically adjust the screen orientation when opening the PDF, then revert it once the viewer closes. Here’s how to do it:

Step 1: Install the Screen Orientation Plugin #

First, you’ll need the cordova-plugin-screen-orientation plugin to control orientation dynamically. Install it via the command line:

cordova plugin add cordova-plugin-screen-orientation

Step 2: Unlock Orientation Before Opening the PDF #

Before calling window.open, unlock the screen orientation to allow all rotations. Then, open your PDF as usual:

// Unlock orientation to allow all rotations
screen.orientation.unlock();

// Open the local PDF in InAppBrowser
const pdfViewer = window.open('path.to.local.pdf', '_blank', 'EnableViewPortScale=yes,location=no,closebuttoncaption=DONE,toolbarposition=top');

Step 3: Revert to Global Orientation When the Viewer Closes #

The window.open call creates an InAppBrowser instance—listen for its exit event to lock the orientation back to your app’s global setting (e.g., portrait) once the user closes the PDF:

pdfViewer.addEventListener('exit', () => {
    // Revert to your app's default locked orientation
    screen.orientation.lock('portrait');
});

Key Notes #

• InAppBrowser Behavior: The InAppBrowser runs in a separate webview, which by default inherits your app’s global orientation settings. The plugin lets you override this temporarily.
• iOS Compatibility: Test this on your target iOS versions—some older iOS versions may have edge cases with orientation locking in webviews.
• Config.xml Context: Make sure your global orientation lock is set in config.xml (e.g., <preference name="Orientation" value="portrait" />)—this is what we’re overriding and reverting to.
