I searched for this topic, and I can't seem to find the right way to parse the JSON string to read the objects.
Here is my code
$.getJSON("<url>",
function(data) {
alert("success!"+data);
});
outputs:
success![object Object],[object Object],[object Object],[object Object]
Firebug shows correct response, and when I click JSON tab I see all the objects.
Thanks!
When a JSON string is parsed, it is turned into a Javascript object. If you use a string method on an object, the string [object Object] is returned.
You need to use object property access methods instead (e.g. alert(data.somekey);).
data[0].somekey since it looks like an Array of Objects.
Don't use alert() for debugging in cases like this if you have Firebug available. Use console.log(data) and you will get direct insights into your JSON data.
In this case you'd have realized that there's absolutely nothing wrong :D .
JSON = JavaScript Object Notation precisely because it is the way to declare object literals in JavaScript. The data parameter is already a Javascript object (in your case an array of objects) that you can access as:
data[index].fieldname
data[i][j] etc... Maybe you could show us your JSON dataUse console.log('data=>',data) if you want to see what is inside of you objects.
$.getJSON. If you want to see the original string, just do a$.get()request instead. Then you can dovar parsed = $.parseJSON(data)to get it parsed. (I assume this is jQuery code.)for/inloop, or you need to have pre-determined knowledge of their content. If for some reason you don't know what the keys are, then use$.get()and look at the string. Or, instead ofalert(data), doconsole.log(data)and open your browser's console. This will let you inspect the content.
