Question

我不断得到一个＆＃34; undifiend＆＃34;尝试使用JSON.parse（result）显示原始json时出错。

＆＃13;

function decodeVin(result)
{
var vinArray = JSON.parse(result);
var results = "<h4>Vehicle Information Result:</h4>";
results += "Year: " + vinArray.years.id + "<br>";
results += "Make: " + vinArray.make.name + "<br>";
results += "Model: " + vinArray.model.name + "<br>";
results += "Sub-Model: " + vinArray.years.trim + "<br>";
results += "Engine: " + vinArray.engine.name + "<br>";
results += "Transmission: " + vinArray.transmission.transmissionType + "<br>";
results += "Platform: " + vinArray.categories.vehicleStyle + "<br>";
results += "Drive Train: " + vinArray.drivenWheels + "<br>";
results += "Exterior Color: " + vinArray.colors.category + "<br>";

＆＃13;

function clearVin()
{
document.getElementById("vin").value = "";
document.getElementById("vin_result").innerHTML = "";
}

function decodeVin(result)
{
var vinArray = JSON.parse(result);
var results = "<h4>Vehicle Information Result:</h4>";
results += "Year: " + vinArray.years.id + "<br>";
results += "Make: " + vinArray.make.name + "<br>";
results += "Model: " + vinArray.model.name + "<br>";
results += "Sub-Model: " + vinArray.years.trim + "<br>";
results += "Engine: " + vinArray.engine.name + "<br>";
results += "Transmission: " + vinArray.transmission.transmissionType + "<br>";
results += "Platform: " + vinArray.categories.vehicleStyle + "<br>";
results += "Drive Train: " + vinArray.drivenWheels + "<br>";
results += "Exterior Color: " + vinArray.colors.category + "<br>";



document.getElementById("vin_result").innerHTML = results;
}

function submitVin(vin, callback)
{
if(vin != "")
{
  var url_prefix = "https://api.edmunds.com/api/vehicle/v2/vins/";
  var url_suffix = "?fmt=json&api_key=zazv2waqgs96hcvfp37dhc22";
  var ajax = null;
  if(window.XMLHttpRequest) // for IE7+, Firefox, Chrome, Opera, Safari
  {
   ajax = new XMLHttpRequest();
  }
  else if(window.ActiveXObject) // for IE5 and IE6
  {
   ajax = new ActiveXObject("Microsoft.XMLHTTP");
  }
  else // a browser not equipped to handle XMLHttp
  {
   window.alert("ERROR: Cound not create XmlHttpRequest Object. Consider upgrading your browser.");
   return(false);
  }
  ajax.onreadystatechange = function()
  {
   if(ajax.readyState == 4 && ajax.status == 200)
   {
    callback(ajax.responseText);
   }
  }
  ajax.open("GET", url_prefix + vin + url_suffix, true);
  ajax.send();
}
}

＆＃13;

<font size="+3"></font>
  <input type="text" id="vin" maxlength="17" placeholder="Enter Vin">
</p>
<button onclick="clearVin();">Clear</button>
<button onclick="submitVin(document.getElementById('vin').value.toUpperCase(), decodeVin);">Decode</button>
</center>
<br>
<div id="vin_result"></div>

＆＃13;

这是JSON原始数据，我将信息显示在..

Answer 1

在你的json中，岁月是一个数组。您必须以这种方式访问它：

VinArray.years[0].id;

请检查这个小提琴：

对不起答案格式。我在打电话。

在Ajax调用（Async）之后显示JSON
