问题 Consider the following HTML code: <script>setTimeout(() => document.querySelector('link').remove(), 0);</script> <link rel="stylesheet" href="http://localhost:8080/test.php"> where http://localhost:8080/test.php is a link to a simple PHP script which just waits 5 seconds ( <?php sleep(5); ). The script removes the link tag as expected, but browser doesn't abort the request to the stylesheet. This doesn't make sense, because when the request is complete, browser doesn't apply the styles anyway

问题 I am using WebRenderer to export HTML5 pages to images on the server. The problem is that the only edition that supports HTML5 is the swing edition.

问题 As we can see browser API is removed from android version > 23, so is there any other method to get browser history with user's permission? Thanks in advance. 回答1: Contrary to the cited documentation, com.android.browser.permission.READ_HISTORY_BOOKMARKS is still defined by the framework, and can still be obtained by apps. Unfortunately, on Marshmallow and later, Chrome checks for a different permission, one that regular apps aren't allowed to obtain. For compatibility reasons, when that

问题 Wrote a server that serves pages dynamically as well as static pages that are loaded into a page array on startup of the server. The server serves pages fine so the delivery is working.
