Jquery adds the shortcut key for the page. Example _ jquery

This article describes how to add shortcuts to pages by jquery. For more information, see The Code is as follows:

$ (Document). keydown (function (e ){
If (e. which = 37 ){
Alert ("Left ");
}
If (e. which = 39 ){
Alert ("right ");
}
});

In addition, a keypress event is similar to a keydown event, but cannot be mixed. The difference between keydown and keypress is:

1 only character buttons can trigger keypress events, any button can trigger keydown events, such as: F1-F12, direction keys, etc. can only use keydown.

2. keydown returns the code of the keyboard, and keypress returns the ASCII character. For example, if the keydown character is a, keydown returns 65, and keypress returns 97.

If you want to check Ctrl, Shift, and other key combinations to determine whether these objects are true: e. shiftKey, e. ctrlKey
