Firefox Error: evt has no properties on javascript console 1

[COTLG]

Hi All,

I get an error on the Firefox javascript console that says:

Error: evt has no properties

This error points to the line starting with two asteriks notations in the code below.

-----------------------------------------------------
var evt;
function mouse_position(){
evt=(evt)?evt(window.event)?event:null);
}
//Display f_menu
var smenuflag;
function f_menuf(objectID){
var object=document.getElementById('f_menu');
if(document.images){
**if ((smenuflag==1)||((smenuflag==0)&&((((evt.clientX+document.body.scrollLeft)>=174)&&((evt.clientX+document.body.scrollLeft)<=360))&&(((evt.clientY+document.body.scrollTop)>=250)&&((evt.clientY+document.body.scrollTop)<=438)))))
{object.style.visibility='visible';}
else object.style.visibility='hidden';
}
}
--------------------------------------------------------

Please how do I correct this problem?

Best Regards,
Chike.

>>window.event

not supported by FireFox. u have to circumvent it:

function Hi(TheEvent)




call Hi like so:
onclick="Hi(event)">



Known is handfull, Unknown is worldfull

Hi vbkris,

Please could you be more elaborate and kindly tell me what to do having the code pasted in perspectve. A fly-out submenu is supposed to be displayed or hidden on moving the mouse above a menu item.

Thanks.

the "event" object cannot be used as used in IE, in all mozilla browsers the event object can only b passed as a parameter, if u want to use it then u have to pass it as a parameter, e.g:

<a href='#' onmouseover="CallMe(event)">TheLink</a>

function CallMe(TheEvent)
{
alert(TheEvent) //u get [object]
alert(window.event) // undefined
}

Known is handfull, Unknown is worldfull

vbkris I understand what you mean but please can you just give me the code?? I am new to javascripting. I want to detect the position of the mouse using the x- and y- coordinates from the evt variable.
