After following the instructions from the answer below:
http://bytes.com/topic/javascript/answers/153274-script-iframe-can-not-call-functions-defined-parent-document
I was able to have the child window perform the function in the parent window.
The function was to only have an alert window pop up as the child page was loading.
I easily modified this to my intention which was to have a parent function performed when the child window was clicked.
Using the body tag:
<body onclick="parent .FUNCTION NAME HERE()">
I first change the method in which the function would be triggered, all went well there. then I tried to change which function would be triggered. (Basically use the function I wanted to happen on click of the child window rather then the function from the test). Once I did this switch, nothing happens.
The site this is being used on is:
http://tylerpanesar.ca/
What I want is when the menu bar is opened, the user chooses a link and the menu closes and goes to that link. This already happens. However if the user opens the menu bar and then changes there mind and continues with the page the are currently on, the menu stays open.
The child window has the same code to call the parent function to call the menu.hide function, but it does not work.
Any help would be greatly appreciated.
Thanks in advance,
Tyler

so ... just to clarify the task ... you want the menu to be closed when the mouse moves out of the menu ... or when the user clicks outside of it?
kind regards
Currently it "hides" only when you choose one of the menu items, but it does not "hide" when you CLICK on your curent page. If you could figure out how to get it to "hide" on a "mouse out" that would be the better option.
I attempted this method however i could only get it to "toggle" the menu on "mouse out". This method does however create an annoying flicker when you hover of the menu items (as it is toggling the open menu command I guess). If I had it "hide" the menu on "mouse out" it would "hide" as soon as you moved off of the main button. The viewer doesn't even have a chance to click a link. or at least that is what happens when I did it. You may have a better method to achieve this.
The script that tells it to hide on click is within a jQuery function: - menua
-
.click(
-
function(){
-
menu.hide();
the code I used for the mouseout toggle was: - menu
-
.mouseout(
-
function(){
-
menu.toggle();
Any help is greatly appreciated.
Thanks,
Tyler

didn't check your code ... but the basic idea would be to assign the mouseout event to the expanded menu ... not to the menu button ... if you want me to check the code you should post the relevant parts here ...

Here is the script that I am currently using for the menu to open and the "click" hide feature.
This menu feature comes from the following help:
http://www.bennadel.co m/blog/1740-Building-A-Fixed-Position-Bottom-Menu-Bar-ala-FaceBook-.htm - <script type="text/javascript">
-
jQuery(function( $ ){
-
var menuRoot = $( "#menu-root" );
-
var menu = $( "#menu" );
-
var menua = $( "#menu a" );
-
// Hook up menu root click event.
-
menuRoot
-
.attr( "href", "javascript:void( 0 )" )
-
.click(
-
function(){
-
// Toggle the menu display.
-
menu.toggle();
-
// Blur the link to remove focus.
-
menuRoot.blur();
-
// Cancel event (and its bubbling).
-
return( false );
-
}
-
)
-
;
-
menua
-
.click(
-
function(){
-
// Toggle the menu display.
-
menu.hide();
-
}
-
)
-
;
-
// Hook up a click handler on the document so that
-
// we can hide the menu if it is not the target of
-
// the mouse click.
-
$( document ).click(
-
function( event ){
-
// Check to see if this came from the menu.
-
if (
-
menu.is( ":visible" ) &&
-
!$( event.target ).closest( "#menu" ).size()
-
){
-
// The click came outside the menu, so
-
// close the menu.
-
menu.hide();
-
}
-
}
-
);
-
});
-
</script>

you are using frames ... as you might have noticed your posted code already deals with clicks outside of the menu ... but the handling is only applied to the bottom frame's document where the menu-script is loaded. you might try to click ouside of the menu there and the menu closes. now you would just need to adopt that handling to the upper frame's documents ...
kind regards
It's actually an iFrame that is 100% wide and high with the menu in the parent. I figured if I were to use regular frames it would not allow the menu to be seen past the frames edge.
I've tried adding the click to "hide" menu feature to the child document but there is now menu in that document for it to "hide".
What I was trying to was have the child document execute a function from the parent document and have that function executed IN the parent document. I've tried the technique from the link in my very first post but I believe it only calls the function from the parent and executes it IN the child. Which does not work for me as the menu is not in the child.
There should be a way to make the child execute a function FOR the parent.

if a function is in the parent and you want to scope the function to be executed there, then you might use the call or apply methods like: - parent.functionName.call(parent, arg1, arg2);
or - parent.functionName.apply(parent, [ arg1, arg2 ]);
kind regards
I think I understand that.
Will I be able to use it in the body tag like I did here: - <body onclick="parent.FUNCTION NAME HERE()">
I'm rather new at trying to do this advanced stuff. I believe I am to put the name of the function I wish to execute in place of your "functionNa me", right?
Next I'm not sure how to use the "function name" I'm trying to apply.
From looking at my code, there is a script that contains a jQuery function. this function contains the "command" I am trying to apply. which is "menu.hide" . I tried simply using that and end up with: - <body onclick="parent.menu.hide.apply(parent, [ arg1, arg2 ])">
But that doesn't work. I think it's the
(parent, [ arg1, arg2 ])
section that has me confused. What are the arg1 & arg2 for?.
Perhaps I am applying the function using the wrong name?
Do I need to set a specific "var" within the jQuery function for just "menu.hide" ?
If so could I simply just do this: - var menuhide = $( "#menu.hide" );
and add this to the existing function: - menuhide
-
function(){
-
menu.hide();

try: - onclick="parent.menu.hide.call(parent, event);"
the arg1...n are parameters that might be passed to a function ... please first try it in FF ... might be that we would need a small adaption for IE?
