我有一个 mysql 查询为我的 json 数据创建这个输出。但是,我无法弄清楚如何访问此输出中的属性。
我尝试使用返回 undefined 和 objA][0] 的 data.objA 并且不知所措。任何帮助将不胜感激。
JSON
({"objA":"yes","objB":[{"username":"ah2122","client_password":"288c0e42ab41faef3d1015e6fc299644","client_id":"36"}]})
PHP
<?php
include 'init.php';
//get the posted values
$user_name=htmlspecialchars($_POST['client_username'],ENT_QUOTES);
$pass=md5($_POST['client_password']);
//now validating the username and password
$sql="SELECT username, client_password, client_id FROM clients WHERE username='".$user_name."'";
$result = mysql_query($sql);
while($row = mysql_fetch_array($result))
{
$rows[] = array(
"username" => $row['username'],
"client_password" => $row['client_password'],
"client_id" => $row['client_id']);
}
//if username exists
if(mysql_num_rows($result)>0)
{
//compare the password
if(strcmp($rows[0]['client_password'],$pass)==0)
{
$SUCCESS="yes";
}
else
$SUCCESS="no";
}
else
$SUCCESS="no"; //Invalid Login
$rows2 = array( 'objA' => $SUCCESS, 'objB' => $rows );
$json = json_encode($rows2);
$callback = $_GET['callback'];
echo $callback.'('. $json . ')';
?>
脚本
$(document).ready(function()
{
$("#client_login_form").submit(function()
{
//remove all the class add the messagebox classes and start fading
$("#msgbox").removeClass().addClass('messagebox').text('Validating....').fadeIn(1000);
//check the username exists or not from ajax
var cu = $("#client_username").val();
var cp = $("#client_password").val();
$.post("http://www.website.com/splash/cajax_login.php",{ client_username:cu,client_password:cp,rand:Math.random() } ,function(data)
{
if(data.objA=='yes') //if correct login detail
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Logging in.....').addClass('messageboxok').fadeTo(900,1,
function()
{
window.localStorage["cusername"] = cu;
window.localStorage["cpassword"] = cp;
//redirect to secure page
document.location="#client_home";
});
});
}
else
{
$("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
{
//add message and change the class of the box and start fading
$(this).html('Login Failed').addClass('messageboxerror').fadeTo(900,1);
});
}
});
return false; //not to post the form physically
});
//now call the ajax also focus move from
$("#client_password").blur(function()
{
$("#client_login_form").trigger('client_submit');
});
