如何在javascript里解析json数据

[shengyunling]

({status:0,
errorMessage:"",
retryCode:51,
data:[
{"root":[
{"head":{"REH_BOTEL":"","REH_DFAX":""},"body":[{"RED_PHO_FIL":"","RED_STAX_AMT":""}]},
{"head":{"REH_BOTEL":"","REH_DFAX":""},"body":[{"RED_PHO_FIL":"","RED_STAX_AMT":""}]}
]}
],
count:3
})
上面是java生成的json数据怎么取得dada里面的数据？像取得status就直接用json.status就可以，但 data里面又包含有数组，该怎么取

请问 在jsp:代码中
$.getJSON(url,
function(json){
var results = json.status;
if(results =="1" || results=="2") {
document.all["error"].innerHTML=json.errorMessage;
} else {
var str = "({";
str += "status:" + json.status + ",";
str += "errorMessage:\"" + json.errorMessage + "\",";
str += "retryCode:" + json.retryCode+",";
str += "data:" + json.data[0] +",";
str += "count:" + json.count + "";
str += "})";
}
});
