Javascript bookmarklet在某些网站上失败，创建了ghostly new< html>页 [英] Javascript bookmarklet fails on certain sites, creates ghostly new <html> page
问题描述
我注意到我的Javascript bookmarklet在Google Reader和Google搜索结果页面等某些网站上失败（在某些非Google网站上随机发布）。看一下控制台，我可以看到，对于这些页面，单击书签并没有像往常一样将元素附加到头部/主体，而是创建了一个如下所示的新文档：
I noticed that my Javascript bookmarklet was failing on certain sites like Google Reader and Google search results pages (and randomly on some non-Google sites). Looking at the console, I could see that, for these pages, clicking the bookmarklet did not append elements to the head/body like it normally did, but created a new document that looked like this:
<html>
<head></head>
<body></body>
</html>
即使我将书签缩小为 javascript：alert（window.location。 href）; 它会创建这个空白页面并在其中运行书签，以便警告显示 about：blank 。在大多数网站上，不会创建此空白页面并显示正确的位置。
Even when I reduced my bookmarklet to javascript:alert(window.location.href); it would create this blank page and run the bookmarklet therein, so that the alert showed about:blank. On most sites, this blank page is not created and the correct location is shown.
有人可以解释一下吗？这些网站是否在沙箱外部运行代码作为安全措施？
Can someone explain this? Are these sites sandboxing externally run code as a safety measure?
更新：我目前无法在Chrome 17.0以外的浏览器上重现这一点。 932.0 dev。如果其他人可以在Chrome或其他方面重现这些结果，请与我们联系。
UPDATE: I currently can't reproduce this on browsers other than Chrome 17.0.932.0 dev. Please let me know if anyone else can reproduce these results on Chrome or otherwise.
