Hi Michael,
I tried, but I've got no response. I double checked the spelling (the
iframe's id and the javascript function's name), and the function is
global.
What I did:
- I'm using jquery-1.2.6.min.js
- inside my head tag I have:
<script type="text/javascript">
;(function( $ ) {
$.fn.frameHook = function( name, hook ) {
this.each( function() {
var win = this.contentWindow;
var target = win[name];
win[name] = function() {
hook.apply( win, arguments );
return target.apply( win, arguments );
};
});
};
})( jQuery );
$('#course').frameHook( 'trivNextPage', function() {
alert( 'about to call trivNextPage' );
});
</script>
but nothing happens when I trigger the trivNextPage function, if I
assign a breakpoint to the line "$
('#course').frameHook( 'trivNextPage', function()" the the firebug
(1.2.0b4) only stops at this point when the page is refreshed. but the
function never is executed.
I don't know if I'm doing something stupid.
Many Thanks
Luiz
