Javascript AJAX-JSON错误

当我试图从服务器端接收数据时，出现以下错误：

06-30 11:23:57.119:I/chromium（7486）：[信息：控制台（50）]“{“readyState”：4，“responseText:”“status”：404，“statusText:”“Not Found”}”，来源：file:///android_asset/www/js/index.js （50）

JS文件：

$j.ajax({ 
    type: 'POST', 
    url: 'http://www.myrandomurl.com/SupportData/login.php', 
    crossDomain: true,
    data:  {email: e, password :p},
    dataType: 'json', 
    async: false,
    success: function (response){ 
        //alert ("response");
        //alert(JSON.stringify(response));
        //console.log(JSON.stringify(response));    
        if (response.success) { 
            myApp.alert("you're logged in");
            //window.localStorage["email"] = e;
            //window.localStorage["password"] = p; 
            console.log(window.localStorage["email"]);                          
            //localStorage.removeItem('email');
            mainView.router.loadPage('main.html');                      
        } else {
            myApp.alert("Your login failed");
            //window.location("main.html");
        }
    },
    error: function(error){                                                 
        //alert(response.success);
        //myApp.alert('Could not connect to the database' + error);
        console.log(JSON.stringify(error));
        //window.location = "index.html";                       
    }
});

PHP方面：

$sql = "SELECT login_id, email_id, password FROM login WHERE email_id='$myusername' and password='$mypassword'";
$result = mysql_query($sql);
$num_rows = mysql_num_rows($result);
$row = mysql_fetch_array($result);

if($num_rows == 1) {
    $response['success'] = true;
}else {
    $response['success'] = false;
}

echo json_encode($response);

正如您在

控制台

中看到的，您得到了

404

，这意味着您的URL不正确。我可以直接访问URL，直接访问时我得到

{“success”：false}
