阅读更多关于 Overriding the F1 key in FF, chrome, ie. Is F1 on ie8/chrome on keyup and in FF on keypress? What about in an input field?

HTML5 Video from a Password Protected directory in Safari

阅读更多关于 HTML5 Video from a Password Protected directory in Safari

问题 Has anyone had a similar problem, and have found a solution? I have a page in a password protected directory that I would like to show video on, using the HTML5 video tag (with video.js, video tag is correct, and all fallback formats are included so no issue there). The problem is that Safari does not seem to play the video files when they are in the same PW protected directory, while all other browsers do. As soon as I move the vid files are out of the PW protected directory it plays fine.
