                  $.ajax({
                      url: "ranktonumber.json",
                      dataType: "json",
                      success: function (data) {
                       // my problem is what should be in this line
                      }
                  });

Like you saw , i have jquery (ajax) command that give me json variable . Let's said that I have another variable called "rank" . "rank" is the key of the json . The json is :

{"Recruit":"1",
"Private":"2",
"Private*":"3",
"Private**":"4",
"Private***":"5",
"Corporal":"6",
"Corporal*":"7",
"Corporal**":"8",
"Corporal***":"9"}

how can i use "rank" in json , because that won't work :

data.rank

If you didn't understand yet , here is how i can do it in mirc :

$json(jsonvariable,rankvariable)

Please vote to close the question as well, it's a duplicate. @user1515823: What is the value of `ranke`? Do `console.log(data)` and `console.log(rank)` and have a look wether the key really exists.

Iv'e made new file with [this source](http://pastebin.com/LszuHAQg) and it alert underfinded – Sep 08 '12 at 11:24
@user1515823: You named the variable holding the object `jsonobject`, not `JSON`. `JSON` is a pre-existing global variable and does not have a property `Private`. Try `jsonobject[rank]`. – Felix Kling Sep 08 '12 at 11:27

@user1515823: The file `ranktonumber.json` cannot be found by the server. Make sure the path is correct. This has nothing to do with your question though. – Felix Kling Sep 08 '12 at 11:40

var thisObj=this;

$.ajax({ 
url: "ranktonumber.json", 
dataType: "json", 
success: function (data) {  
thisObj.data=data;
});

console.log (thisObj.data["rank"])
