Use the keycode attribute of the event object to determine the Input key value
Eg: If (event. keycode = 13) Alert ("Enter !");

C 0x67 w 0x87
D 0x68X0x88
E 0x69 Y 0x89
F 0x70 Z 0x90

P 0x80 9 0x57
Q 0x81 ESC 0x1b
R 0x82 CTRL 0x11
S 0x83 shift 0x10
T 0x84 enter 0xd
If you want to use the combination key, you can use event. ctrlkey, event. shiftkey, event. altkey to determine whether Ctrl, shift, and ALT keys are pressed.

JS event object event attributes and methods:

1. Type: Transaction type, such as click in onlick;

2. srcelement/target: the transaction source, which is the production element;

3. button: Declares the mouse key to be pressed. An integer. 1 indicates the left button, 2 indicates the right button, and 4 indicates the middle button. If you press multiple keys, add these values to the wine, so "3" means that you press the key at the same time. (In Firefox, "0" indicates the left button, "1" indicates the center key, and "2" indicates the right button)

4. clientx/clienty: the time when the transaction is generated. The cursor is relative to the upper left corner of the visible document area in the browser window, that is to say, no matter where the document is migrated, as long as the transaction is generated in the upper left corner of the window, clientx and clienty are both 0. Therefore, in IE, to obtain the starting position of the coordinates produced by the transaction relative to the document, add
Document. Body. scrollleft and document. Body. scrolltop)

5. offsetx, offsety/layerx, layery: the time when the transaction is generated, and the position of the cursor relative to the upper left corner of the source element;

6. x, y/pagex, Pagey: returns the integer of the degree of coordinates relative to the mouse of the parent element;

7. altkey, ctrlkey, and shiftkey: return a Boolean value;

8. keycode: return the key at which the keyup transaction is generated.CodeAnd Unicode characters of the keypress transaction. (firefox2 does not support event. keycode. You can use event. Which to replace it)

9. element, toelement: The former refers to the document element that the mouse has moved in the MOU Search Engine Optimization ver transaction, and the latter refers to the file element that the mouse has moved to in the MOU Search Engine Optimization ut transaction;

10. cancelbubble: A boolean attribute. When it is set to true, the stop transaction is further blister to the element of the inclusion level; (E. cancelbubble = true; equivalent to E. stoppropagation ();)

11. returnvalue: A boolean attribute. When it is set to false, the browser can be organized to perform the default transaction action. (E. returnvalue = false; equivalent to E. preventdefault ();)

12. attachevent (), detachevent ()/addeventlistener (), removeeventlistener: two parameters are provided to register multiple transaction processing penalty functions for the DOM object transaction type, the first is the transaction type, and the second is the transaction processing penalty function. In
When the attachevent () transaction is executed, this keyword points to the window object, not the production element;

13. screenx and screeny: the position of the mouse pointer relative to the upper left corner of the monitor. If you want to open a new window, these two attributes are very important;

Some statements:

1. Event indicates the transaction status, such as the element that triggers the event object, the position and status of the mouse, and the key that is pressed;

2. The event object is valid only when the transaction is generated.
The event in Firefox is different from the event in IE. The global variables in IE are available at any time. The parameters in Firefox are used to seduce and use them, which is an extra variable in runtime.
In IE/opera, window. event is used and event is used in Firefox. in IE, the transaction object is event.srcelement, event.tar get is used in firefox, and both are available in opera.

3. The following two statements have the same results.
VaR EVT = (EVT )? EVT: (window. Event )? Window. Event: NULL );
VaR EVT = EVT | window. event; // in Firefox, window. event is null, and in IE, event is null.

4. Transaction bubbles in IE
In IE, transactions can bubble to the upper layer a little along the inclusion level, that is, the transaction processing penalty function defined by the DOM node at the grassroots level, if a node at the upper layer has a transaction processing penalty function of the same transaction type as that at the lower layer, the upper layer will also perform the penalty function. For example, the DIV tag contains a. If both tags have an onclick transaction processing penalty function, the fulfillment scene is to first perform The onclick transaction processing penalty function of tag, then execute the DIV's transaction processing penalty function. If the transaction processing penalty function does not fulfill the onclick transaction processing penalty function of the upper Div, set cancelbubble to true.
