I think I see what you're doing - you're copying the demo program
which is
more for demonstrating various effects together instead of
demonstrating
proper syntax, but your code doesn't include the variables they used,
based
on what you posted.
Something like this would be your actual usage: (I don't have the
ui.effects
so I haven't tested this, but it should be ok)
$('#details_'+onderwerp).show("blind",{ direction: "horizontal" },
500,function(){
onOnderwerpChange(onderwerp);
});
function onOnderwerpChange(onderwerp) {
alert(onderwerp);
};
This page: http://docs.jquery.com/UI/Effects/Blind
has the basic show syntax without the callback.
{ direction: "horizontal" } is the type of thing that would be in the
option
variable in the demo.
And just a tip: If you aren't already, start using firebug and
console.log for
script development instead of relying on alert-it will make your life
easier.
