我想使用PhoneGap應用程序接收JSON數據。我正在使用服務器xampp php服務器。在此服務器上,我有用於從數據庫接收數據的服務器代碼api.php。我的筆記本電腦的IP地址是192.168.1.4 所以這本地服務器的URL是HTTP://192.168.1.4/Experiements/webservices/api.php」如何將JSON數據寫入phonegap應用程序中的html元素?
我能夠接收數據使用
alert(JSON.stringify(response));
,但我想這_email_id_信息添加到
<div id="email">Email_id</div>
這是在
指數定義
.html。
從我的Android手機我想只是登錄,並收到該用戶的email_id。請使用 警報(JSON.stringify(響應))查看我的數據庫和數據在手機上接收的圖像。
我的服務器代碼是api.php
<?php
header('Access-Control-Allow-Origin: *');//Should work in Cross Domaim ajax Calling request
mysql_connect("localhost","root","1234");
mysql_select_db("demo");
if(isset($_GET['type']))
{
if($_GET['type']=="login"){
$username=$_GET['UserName'];
$Password=$_GET['Password'];
$query="Select * from registration where UserName='$username' and Password='$Password'";
$result=mysql_query($query);
$totalRows=mysql_num_rows($result);
if($totalRows>0){
$recipes=array();
while($recipe=mysql_fetch_array($result, MYSQL_ASSOC)){
$recipes[]=array('User'=>$recipe);
}
$output=json_encode(($recipes));
echo $output;
}
}
}
else{
echo "Invalid format";
}
我PhoneGap的應用程序代碼是在的index.html
