没有解析JSON数据？

Question

I followed the advice here on how to use JSON.

After using

$resultAml =  json_encode($resultArray);

in PHP I get this at the client:

[{"id":"1","0":"1","title":"Facebook","1":"Facebook","url":"http://facebook.com","2":"http://facebook.com","domain":"facebook.com","3":"facebook.com","tag":"","4":""},{"id":"1","0":"1","title":"Ideeli","1":"Ideeli","url":"http://www.ideeli.com","2":"http://www.ideeli.com","domain":"ideeli.com","3":"ideeli.com","tag":"web","4":"web"},{"id":"1","0":"1","title":"Kikin","1":"Kikin","url":"http://www.kikin.com","2":"http://www.kikin.com","domain":"kikin.com","3":"kikin.com","tag":"web","4":"web"},{"id":"1","0":"1","title":"Lot18","1":"Lot18","url":"http://www.lot18.com","2":"http://www.lot18.com","domain":"lot18.com","3":"lot18.com","tag":"web","4":"web"},{"id":"1","0":"1","title":"Quora","1":"Quora","url":"http://quora.com","2":"http://quora.com","domain":"quora.com","3":"quora.com","tag":"","4":""},{"id":"1","0":"1","title":"Twitter","1":"Twitter","url":"http://twitter.com","2":"http://twitter.com","domain":"twitter.com","3":"twitter.com","tag":"","4":""}] 

That looks like valid JSON according to json.org

Howwever,

When I parse it on the client side using

JSON.parse

I get this result:

[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Looks like one [object Object] for each entry in the table.

What is object Object?

Where did I go wrong here? Or if not how do I get to the data in the result?

Answer 1

You have the data, you just misunderstand how it's being displayed. The default string representation of any JavaScript Object, which is what JSON {...} values are, is just [object Object]. If you try to access the properties of the objects you will see that the data you expect is there:

var input = '[{"id":"1","0":"1","title":"Facebook","1":"Facebook","url":"http://facebook.com","2":"http://facebook.com","domain":"facebook.com","3":"facebook.com","tag":"","4":""},{"id":"1","0":"1","title":"Ideeli","1":"Ideeli","url":"http://www.ideeli.com","2":"http://www.ideeli.com","domain":"ideeli.com","3":"ideeli.com","tag":"web","4":"web"},{"id":"1","0":"1","title":"Kikin","1":"Kikin","url":"http://www.kikin.com","2":"http://www.kikin.com","domain":"kikin.com","3":"kikin.com","tag":"web","4":"web"},{"id":"1","0":"1","title":"Lot18","1":"Lot18","url":"http://www.lot18.com","2":"http://www.lot18.com","domain":"lot18.com","3":"lot18.com","tag":"web","4":"web"},{"id":"1","0":"1","title":"Quora","1":"Quora","url":"http://quora.com","2":"http://quora.com","domain":"quora.com","3":"quora.com","tag":"","4":""},{"id":"1","0":"1","title":"Twitter","1":"Twitter","url":"http://twitter.com","2":"http://twitter.com","domain":"twitter.com","3":"twitter.com","tag":"","4":""}]';
var data = JSON.parse(input);
alert(data[0].title); // displays "Facebook"
