如何阅读http回复？

Question

我只想在div中打印http响应的一个字段。

这是我的http请求：

var HttpClient = function() {
  this.get = function(aUrl, aCallback) {
    var anHttpRequest = new XMLHttpRequest();
    anHttpRequest.onreadystatechange = function() {
      if (anHttpRequest.readyState == 4 && anHttpRequest.status == 200)
        aCallback(anHttpRequest.responseText);
    }
    anHttpRequest.open("GET", aUrl, true);
    anHttpRequest.send(null);
  }
}
var theurl = 'https://geocoder.cit.api.here.com/6.2/geocode.json?searchtext=200%20S%20Mathilda%20Sunnyvale%20CA&app_id="MYAPPID"&app_code="MYAPPCODE"&gen=8';
var client = new HttpClient();
client.get(theurl, function(response) {

  var response1 = JSON.parse(response);
  //alert(response);

});

我知道要打印Div中的响应，我必须使用：

 document.getElementById('test').innerHTML = [...];

但是我不知道该如何读字段："Latitude"

这是整个http响应：
