前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

远程数据如下：<br/>
<div id="remote"></div>
</body>

http://www.ogtest.com/login/login/checkpwd PHP代码如下:
@H_
301_47@$loginId = stringHelper::searchTrim($this->getParam("loginId"));

$userIdRemember = stringHelper::searchTrim($this->getParam("userIdRemember"))?TRUE:FALSE;

$arrCondition["loginId"] = $loginId;
$arrCondition["pwd"] = $pwd;
//记住
用户登录状态
$userRemember = $this->_request->getCookie('userRemember');
$arrCondition['userRemember'] = json_decode($userRemember,true);
if ($this->getParam("chkUserIdRemember") == "on") {
$arrCondition["userIdRemember"] = TRUE;
} else {
$arrCondition["userIdRemember"] = FALSE;
}
$crossdomain = stringHelper::searchTrim($this->getParam("crossdomain"));
$return = $this->_facade->pbLogin($arrCondition);
if($crossdomain==false){
//非跨域
调用
if($return['isError']==false){
//密码和账号正确
$arrOutPut = array("result"=>'1');
}else{
//密码和账号不正确
$arrOutPut = array("result"=>'0');
}
jsonHelper::outPutJson($arrOutPut);
}else{
//跨域
调用

}else{
//密码和账号不正确
$str = '[{"result":"0"}]';
}
$jsonp = $_REQUEST["callback"];
$str = $jsonp . "(" .$str.")";
echo $str;
exit;
