How can I store data from an AJAX function in a json-array?

Hey,

I need to gather somer data for a jQuery function. I need this data to
be a json array, which I will achieve in a php action which returns an
array that is encoded as JSON.

So far, so good.

I need sth like this:

$.ajax({
url: '/controller/action',
data: "ajax=true",
dataType: 'json',
complete: function() {
},
success:
});
}
})

but how can I store the data of the returned array into a variable
which I can then use in other functions of my codeblock?

I think this one is easy but I just started learning it and don't know
how to do it

Thanks,

DD

You shouldn't be thinking in terms of "storing the JSON data in a variable
for other functions to use."

Instead, you should *call* those other functions from your success callback,
and pass the JSON data as an argument to those functions.

Remember that Ajax calls are asynchronous (the A in Ajax). If you store the
data in a variable, how will those other functions know when it is ready for
use? By calling those functions from the success callback, you insure that
the data is ready and available at the moment of the call.

If you have a more complete example I can probably suggest something more
specific.

Hey,

ok I need to solve this:

data : function(start, end, callback) {
callback(getEventData());
}

Here my data parameter is builded, and the function that is used looks
like this:

function getEventData() {
return {
events : [
{
"id":1,
"start": new Date(year, month, day, 12),
"end": new Date(year, month, day, 13, 30),
"title":"Lunch with Mike"
}]
}
}

So I need to replace that returning of a directly declared json-array
with an ajax function that gets the data I want to display for me.

I hope there is a solution, it would be very nice because I'm trying
to populate a jQuery calendar with dynamic data...
