has no properties

I have a js function

function focus(WhereFocus){WhereFocus.focus}

in a js script block. It's called from body onload event:

<body onLoad="focus(<%=WhereFocus%>);">

this is within a vbscript function which writes the header of each page in an application; I pass this function the name of the page and where I want initial focus for the page to be. Many times it is simply 'document' but sometimes it's to a form element.

It is getting written to html like this:

<BODY onLoad="focus(document.login.ID);">
or
<BODY onLoad="focus(document);">

It works fine in IE and NS7, though in NS7 if I invoke the js console I see the report:

Error: WhereFocus has no properties

In Netscape 4.7, focus is put correctly, but I get this error:

WhereFocus is not a function.

Anyone know what I'm doing wrong?

Thanks -

A few things...

First off you're always asking for trouble when you use reserved words for function names or variables. So instead of calling your function "focus" which as you know is an object method name I'd call it "setfocus".

After WhereFocus.focus try adding (); and sometimes, some browsers will want you to put javascript: in front of the function call.

Code: Select all

function setfocus(WhereFocus){WhereFocus.focus();}

and

<body onLoad="javascript:setfocus(<%=WhereFocus%>);">

But really, there's no reason to have a function that only does one thing, so you might as well cut down you code by removing the jscript function and doing

Code: Select all

<body onLoad="javascript:<%=WhereFocus%>.focus();">
