C++ (Cpp) promiseRejectHandler示例

示例#1

文件： V8Initializer.cpp 项目： JiangSuyong/chromium

static void promiseRejectHandlerInMainThread(v8::PromiseRejectMessage data)
{
    ASSERT(isMainThread());

    v8::Local<v8::Promise> promise = data.GetPromise();

    v8::Isolate* isolate = promise->GetIsolate();
    // There is no entered window during microtask callbacks from V8,
    // thus we call toDOMWindow() instead of enteredDOMWindow().
    LocalDOMWindow* window = currentDOMWindow(isolate);
    if (!window || !window->isCurrentlyDisplayedInFrame())
        return;
