javascript - Chrome更新后的“Violation readystatechange handler took 760ms”

更新Google Chrome v57.0.2987后，
打开Collorbox时，我们的网站出现错误:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help, check https://xhr.spec.whatwg.org/.

    [Violation] 'readystatechange' handler took 760ms
    [Violation] Forced reflow while executing JavaScript took 51ms
    [Violation] Forced reflow while executing JavaScript took 43ms
    [Violation] Forced reflow while executing JavaScript took 38ms

这仅在有时发生。当我们收到这些错误时，Colorbox对我们不起作用。
Google Chrome浏览器可能存在错误吗？
编辑:
Magento合并JavaScript导致此错误。这是行不通的。如果我不合并它们，那么我不会得到这些错误，并且正确加载。

VM23586:4 Uncaught TypeError: Cannot set property 'value' of null  at choose (eval at <anonymous> (0a9e2e3….js:11743), <anonymous>:4:73)  at HTMLImageElement.onclick (letto-moderno-imbottito-prisma.html:1)
Uncaught TypeError: Cannot read property 'close' of undefined  at HTMLDivElement.onclick (letto-moderno-imbottito-prisma.html:1)

最佳答案

Chrome只是说您的代码is blocking the UI too much。
