json
昨天写一个功能：点击手机验证的同时获取json端的数据。
javascript代码如下：
$(.check_mobile).click(function(){var mobile = $('.mobile').val();$.getjson(http://www.test.com/user.php?mobile=+mobile+&format=json&jsoncallback=?, function(data){if (data.succ == 1) {var html = ;$(.r_m).append(html);}});});
user.php代码如下：
'石家庄','cityid' =>'1','community' =>'紫晶悦城','communityid'=>'1');$sucess = 1;$return = array('succ' =>$sucess,'data' => $user);}else {$sucess = 2;$return = array('succ' =>$sucess);}echo json_encode($return);}?>
相应如下：
问题出来了：
在火狐浏览器中： syntaxerror: missing ; before statement
解决方法如下：
header(access-control-allow-origin:http:www.test.com);$b = json_encode($return);echo {$_get['jsoncallback']}({$b});exit;
最后完整代码：
'石家庄','cityid' =>'1','community' =>'紫晶悦城','communityid'=>'1');$sucess = 1;$return = array('succ' =>$sucess,'data' => $user);}else {$sucess = 2;$return = array('succ' =>$sucess);}$b = json_encode($return);echo {$_get['jsoncallback']}({$b});exit;}?>
如果在 php 中少了 header(access-control-allow-origin:http:www.test.com); 代码，则会出现
xmlhttprequest cannot load ''. no 'access-control-allow-origin' header is present on the requested resource. origin ' ' is therefore not allowed access.
如果少了 echo {$_get['jsoncallback']}({$b}); 代码
在谷歌浏览器中：uncaught syntaxerror: unexpected token :
在火狐浏览器中：syntaxerror: missing ; before statement
