I've seached high and low, and have had no luck finding the answer to this one.
I've got a json file that i'm using .each on. Have a look at the .json format - it's got a couple sub arrays:
http://heykoolaid.com/sections2.json
Here is the .html
http://heykoolaid.com/json_output.html
As you can see, it's just writing "[object Object]," as it runs through the arrays.
What am I doing wrong?
And how can i access the sub arrays ?
By now, I've pretty much got my head around this shizz, but i'm still lost when it comes to accessing the sub array data
Here is the code: (json)

and the html:
<script type="text/javascript">
$(function() {
$.getJSON("sections2.json", tickets);
function tickets(data) {
var htmlString = "";
$.each(data.zones, function(index, value) {
htmlString += item.sections + "<br/>";
});
$('#test').html(htmlString);
}
});
If you know exactly what you need from the data structure then you can just descend though the struture, eg.
data.zones[i].sections[j].name // Access known location in data structure
If you need to iterate, then jQuery's each() function is quite handy:
$.each(data, function (i, zone) {
//do stuff with zone data eg. print zone.id
$.each(zone.sections, function (j, section) {
//do stuff with section data, eg. print section.name
});
});
Or iterating using just JavaScript:
for (i in data.zones) {
zone = data.zones[i];
// print zone.id
for (j in zone.sections) {
section = zone.sections[j];
// print section data
}
}
you can use
$.each({arr},function(index, value){
alert(index + ': ' + value);
}
);
he $.each()
function can be used to iterate over any collection, whether it is a map (JavaScript object) or an array
Please refer to the usage of the getJSON http://api.jquery.com/jQuery.getJSON/
I don't think you are passing the data to the success handler. If you follow the example from the link above, you should be in the right direction.
Success handler example:
$.getJSON('ajax/test.json', function(data) {
$('.result').html('<p>' + data.foo + '</p>'
+ '<p>' + data.baz[1] + '</p>');
});
Your tickets(data) function is not getting the data after the getJSON completes.
