我在论坛上搜索了所有对我有帮助的东西，但都没有工作。。。我试图使用AJAX调用远程服务器中的PHP文件登录Phonegap，但PHP文件没有返回任何内容。。。我张贴我的代码：
AJAX调用：
$.ajax({
type: "POST",
data: 'userMail='+user+'&userPassword='+password,
dataType : 'html',
url : "http://www.eega.nl/app/login.php",
crossDomain: true,
async: false,
success: function(data){
if(data!='error'){
window.localStorage["userId"] = data;
location.href = "schedule.html";
}else{
alert("failed login");
location.href = "index.html";
}
},
error: function(){
alert("error");
window.open('schedule.html');
}
});
PHP文件：
<?php
include 'connect.php';
header('Access-Control-Allow-Origin:*');
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS, REQUEST');
header('Content-Type: application/json; charset=utf-8');
header('Access-Control-Max-Age: 3628800');
$data = array();
$userMail = $_POST["userMail"];
$userPassword = $_POST["userPassword"];
$cryptpass = md5($userPassword);
$sql = "SELECT tr_adr_id FROM elo_users WHERE email = '" . $userMail . "' AND crypt = '" . $cryptpass . "'";
//mysql_real_escape_string($userMail),
//mysql_real_escape_string($cryptpass));
$result = mysqli_query($sql);
//if($data = mysql_fetch_array($result)){
while($row = mysqli_fetch_array($result)) {
$data = $row['tr_adr_id'];
}
echo $data["tr_adr_id"];
mysqli_free_result($data);
mysqli_close();
?>
我试着用POST和GET进行AJAX调用，并在PHP文件中用$_POST、$_GET和$_REQUEST进行调用，但这些都不起作用…
提前谢谢！我仍在努力找出代码中的错误。。。

你做的事情对自己来说有点困难——一切都是这样安排的。这里有几个示例可以帮助您修复代码。
请注意数据：｛｝是如何布局的。注意成功是如何安排的。
$.ajax({
type: "GET",
url: "../ajax.php",
dataType: "json",
data: {
type: "getLineComments",
saleId: $(this).attr('saleId'),
lineId: $(this).attr('lineId')
},
success: function (json) {
$content.empty();
$content.slideToggle(500, function () {
if(json.Row !== undefined && json.Row.length > 0)
{
for(var i=0;i < json.Row.length;i++)
{
var item = json.Row[i];
//console.log(item);
//console.log(item.REMARK_LIN);
$content.append("<li>" + item.REMARK_LIN + "</li>");
}
}
else
{
if(json.Row !== undefined)
$content.append("<li>" + json.Row.REMARK_LIN + "</li>");
else
$content.append("<li>No Comments</li>");
}
$header.text(function () {
//change text based on condition
return $content.is(":visible") ? "Collapse Line Remarks" : "Expand Line Remarks";
});
});
},
error: function(e)
{
console.log(e);
}
});
还有一件事会对您有很大帮助，那就是使用php函数json_encode-http://php.net/manual/en/function.json-encode.php
例如
echo json_encode(mysqli_fetch_array($result));
