How to get a specific value in this json - json

Question

I have question, I hava a json with some information and I need to get a specific value, for example the Location, I had created a function but it doesn´t work fine, I get this error message about the " "
SyntaxError: invalid label
"location" : "Austin-Bergstrom International Airport,
The function is this one
function lee_json() {
var temp = ('http://df9e7c46aa4c80573717-1199cc892ebab574a120721e4772cd8b.r11.cf2.rackcdn.com/services/aus.json');
temp2 = temp.location;
alert(temp2);
console.log(temp);
console.log(temp.location);
}
and the Json is this one
{
"location" : "Austin-Bergstrom International Airport, Tx",
"city" : "Austin",
"state" : "Tx",
"dewPointC" : 4.4,
"visibilityMiles" : 10,
"rainChance" : "10%"
}
What can be the problem ?

Answer 1

try this http://msdn.microsoft.com/en-us/library/ie/cc836466(v=vs.94).aspx this might be the kind of answer you're looking
if i assume you are using jquery you can use this
http://api.jquery.com/jQuery.getJSON/

Answer 2

Assuming 1) you are running this on the same domain where the json is hosted, 2) you have jquery, 3) the result is a json object, not an array, this is a legit example of getting a field:
function getData(aLink) {
$.getJSON(aLink,
function(data) {
console.log(data.location);
});
}
getData("http://df9e7c46aa4c80573717-1199cc892ebab574a120721e4772cd8b.r11.cf2.rackcdn.com/services/aus.json");
