问题 I would like to know whether the user pressed F1 or F2 or F3 or F4 or F5 or ESC and perform an action after that but I don't know how to get these keys. Can anyone help? 回答1: For Windows, there is the _getch function, which returns the bytes of a key code, one by one.

问题 A HTML page is created using JSF and facelets (xhtml). There are 2 h:forms that goes to different places. The user enters data on one form and presses the "Enter" key. Here is where it gets tricky. On IE 6 and above, either the forms action gets submitted (which usually points to the page you are on) which then just reloads the page, or the first h:commandbutton/link that is on the page.

So your question is, "How do I display content on my page only

问题 I've had several occasions in my selenium tests where I decided to use Selenium's click_and_hold() (source code here) method on some element. The source code makes it look like it will stay pressed indefinitely but there are definitely some actions, such as a simple click, that cause the held click to be released. Obviously calling release will release the held click too, but does anyone have a grasp on exactly what actions/conditions (either from the script or the page itself) will cause the
