Question

当nativeDriver为false时，可以使用._value获取当前动画值。

但是当nativeDriver设置为true时，是否可以获得当前值？

我们有什么解决方法吗？

Answer 1

像这样使用addListener

ParallaxView

Answer 2

我想出了一种解决此类情况的方法，其中本机驱动程序破坏了我们的偏移量，并最终使动画跳转了。

创建一个伪动画值（不会用于任何动画），并与原始动画值一起不断更新。最后，当动画结束时（例如衰减，弹簧等），使用伪值设置偏移量和当前角度，如下所示：

use Nesk\Puphpeteer\Puppeteer;
use Nesk\Rialto\Data\JsFunction;
use Nesk\Puphpeteer\Resources\ElementHandle;


public function scrapeFacebookForBirthdays()
    {
        $cookies = null;

        $puppeteer = new Puppeteer();
        $browser = $puppeteer->launch([ 'headless' => false, 'slowMo' => 250 ]);
        $browser->setUserAgent('Opera/9.80 (Windows NT 6.2; WOW64) Presto/2.12.388 Version/12.17');

        $page = $browser->newPage();

        
        //Check if cookies are set or not, if not set it means we have to log in ONCE, but HOW to cjeck for cookies, where to save them?
        if (!$cookies)
        {
            $page->goto("https://www.facebook.com/login", [ 'waitUntil' => "networkidle2" ]);
            $page->type("#email", $username, [ 'delay' => 30 ]);
            $page->type("#pass", $password, [ 'delay' => 30 ]);
            $page->click("#loginbutton");

            sleep(5);

            $page->waitForNavigation([ 'waitUntil' => "networkidle0" ]);

            try 
            {
                echo "success login";
                $page->waitFor('[data-click="profile_icon"]');
            }
            catch (Exception $e)
            {
                echo "failed to login";
                $browser->close();
            }

            //Where to save cookies for next url scrape??
            $cookies = $page->cookies();
        }
        else
        {
            //User Already Logged In
            $page->setCookie($cookies);
        }
    }

当nativeDriver为true时，如何获取当前的Animated.value？
