如何让我的用户脚本在隔离沙箱和 unsafeWindow 中执行代码？

Question

For most of my code in my userscript, I'm need to use unsafeWindow for the websites my script executes on. I do this by using // @grant unsafeWindow . However, some of my code cannot be executed with unsafeWindow and needs to run in Tampermonkey's isolated sandbox. How would I be able to do this? Something like this could work:

function disableUnsafeWindow() {
    // Disable UnsafeWindow
}

function enableUnsafeWindow() {
    // Enable unsafeWindow
}
function withUnsafeWindow() {
    enableUnsafeWindow()
    // Run the code using unsafeWindow
}

function withoutUnsafeWindow() {
    disableUnsafeWindow();
    // Remove unsafeWindow access and execute the code without unsafeWindow
}

withUnsafeWindow()
withoutUnsafeWindow()

Use the isolated sandbox with the privileged userscript functions by default. Then, for the code that requires use of the native page, you could insert the code into a <script> tag, eg:

 const fnToRunOnNativePage = () => { console.log('fnToRunOnNativePage'); }; const script = document.body.appendChild(document.createElement('script')); script.textContent = '(' + fnToRunOnNativePage.toString() + ')();'; // to use information inside the function that was retrieved elsewhere in the script, // pass arguments above script.remove();
