how to get a jumpmenu to open in specified new window

I have a web page with many links opening in a new window. The opening of this new window is governed by a JS Function that I wrote:

function newWindow(bookjpg) {
bookWindow = window.open(bookjpg, "bookWin", "toolbar=yes,location=yes,status=yes,menubar=yes,scrollbars=yes,resizable=yes,width=870,height=800")
bookWindow.focus()
}
This is workign perfectly for all the links on the page-opening in the correct window. But, I have a jumpmenu that also links to various parts of my site that I want to be governed by this same newWindow function. Of course, it is not and I do not know how to integrate these two functions. Here is the code for the jumpmenu:

function MM_jumpMenu(targ,selObj,restore){ //v3.0
eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
if (restore) selObj.selectedIndex=0;
}

and here is the code that calls this function in the body:

onChange="MM_jumpMenu('newWindow()',this,0)">

As you can see I have substituted 'newWindow' for the target info. This is not working. (This was my best guess at trying to make this work). When I test this in the browse I get the error 'undefined' is null or not an object. I think it is stemming from the eval() part of the jumpmenu code.

Any thoughts?

Put a target parameter in the newWindow function.

function newWindow(bookjpg, target) {
var bookWindow = window.open(bookjpg, target, "toolbar=yes,location=yes,status=yes,menubar=yes,sc rollbars=yes,resizable=yes,width=870,height=800");
bookWindow.focus();
}

function MM_jumpMenu(targ,selObj,restore){ //v3.0
newWindow(selObj.options[selObj.selectedIndex].value, targ);
if (restore) selObj.selectedIndex=0;
}
...
onChange="MM_jumpMenu('mywin',this,0)"

then change the call to newWindow by all the links to:

newWindow('url', 'bookWin')

But if you want all the links and the pages in the option items opened to the same popup window, the targ parameter in the call to the MM_jumpMenu function on onchange event, should be the same with that of the links:

onChange="MM_jumpMenu('bookWin',this,0)"
