Question

这是我的HTML代码：

<!DOCTYPE html>
<html>
  <head>
    <script src="jquery-2.1.1.js"></script>
    <script charset="utf&minus;8" type="text/javascript">
        $.support.cors = true;
        function connect(e) {
          $.ajax({
            url: 'http://192.168.0.100/xxx/index.php',
            type: 'POST',
            async: false,
            crossDomain: true,
            error: function(jqXHR,text_status,strError) {
              alert("no connection");
            },
            timeout: 60000,
            success: function(data) {
              alert("success");
              $("#result").html(JSON.stringify(data));
            }
          });     
        }
    </script>
  </head>

  <body>
    <center><b>Bikes or Cars</b></center>
    <center><input onclick="connect(this.value)" type="button" value="cars" /></center>
    <center><input onclick="connect(this.value)" type="button" value="bikes" /></center>
    <center><b>Results</b></center>
    <ul id="result"></ul>
  </body>
</html>

PHP：

<?php
header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Credentials: true");
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');
header('Access-Control-Allow-Headers: Content-Type, Content-Range, Content-Disposition, Content-Description');
$choice =$_POST["button"];
$cars = array("Honde", "BMW" , "Ferrari");
$bikes = array("Ducaite", "Royal Enfield" , "Harley Davidson");
if($choice == "cars") print json_encode($cars);
else print json_encode($bikes);
?>

问题是当我从谷歌浏览器运行此代码时，响应是：

"[\"Ducaite\",\"Royal Enfield\",\"Harley Davidson\"]"

但是当我尝试从我的Android设备运行它时，我得到一个空字符串或null响应的响应。我现在不知道为什么我已经添加了

<access origin="*" />

我的config.xml和我的清单中的

是

<uses-permission android:name="android.permissions.INTERNET" />
<uses-permission android:name="android.permissions.NETWORK_ACCESS" />
<uses-permission android:name="android.permissions.ACCESS_NETWORK_STATE" />

Phonegap ajax没有响应文字？
