Problems accessing multidimensional array

Question

So i'm running a $.getJSON statement and i'm having some problems... here's the json:

{ "K-6608-1-0": [ { "Info": [ { "SVGFile": "46658.svg", "Name": "Faucet Parts" } ], "Parts": [ { "Cod":"70012", "Name":"Ruela de Parafuso Reforçado B2", "Price":"$100" }, { "Cod":"71131", "Name":"Parafusasdasdasdsdao Reforçado B2", "Price":"$45" }, { "Cod":"78208", "Name":"Tubo de Conexão R2D2", "Price":"$150" } ] } ] }

So, let's say i've made the getJSON that way:

$.getJSON('test.json', function(data){ alert(data["K-6608-1-0"]["Info"]["SVGFile"]); })

Why this code doesn't return "46658.svg"? Where's the error?

Thanks in advance ^^

data["K-6608-1-0"] is an array containing one element which is an object, so is Info. You want data["K-6608-1-0"][0]["Info"][0]["SVGFile"] — Matt

K-6608-1-0 and Info are arrays, so you have to set the position.

alert(data["K-6608-1-0"][0]["Info"][0]["SVGFile"]); ^ ^

That's because data["K-6608-1-0"] is an array, so to access the property you want, first you have to access an element of this array bi its index (data["K-6608-1-0"][0]["Info"] is also an array):

$.getJSON('test.json', function(data){ alert(data["K-6608-1-0"][0]["Info"][0]["SVGFile"]); // ^ ^ });

alert(data["K-6608-1-0"][0]["Info"]["SVGFile"]); ^^^--- add this

you've got arrays nested in objects nested in arrays nested in.... The first K-whatever is actually an array. You'll probably have to do the same for deeper levels as well.

You forgot a [0] after ["Info"], since it's an array too
