The method for obtaining the keyboard code in IE and FF is somewhat different.

In IE, we can directly use window. event. keycode to obtain the keyboard code, but this statement is not supported in ff. The followingCodeSo that we can be compatible with them.

<InputType= "Text"Value= ""Onkeypress= "Testcode (event )"/>

<SCRIPT type = "text/JavaScript" Language = "JavaScript">
FunctionTestcode (e ){
VaRVal = Window. event? E. keycode: E. Which;
Alert (VAL );
}
</SCRIPT>

Because the window object in FF does not have the event attribute (you can directly obtain the window in IE. event), we need to input an event object when calling the function, so that we can get the keyboard code.

I would like to share some tips with you.
