sarafi浏览器iframe跨域cookie无效的处理方案(笨方法，看官莫笑)

<script>
    $(function(){
        url = 'oauth_authorize_api';
        loaded = false;
        iframe = '<iframe id="login" width="100%" height="500" src="' + url + '"></iframe>';
        $(".test").click(function(){
            if(loaded) return false;
            if(!/chrome\/\d+/.test(navigator.userAgent.toLowerCase()) && /safari\/\d+/.test(navigator.userAgent.toLowerCase())) {
                myWindow = window.open(url,"myWindow",'width=1,height=1');
                setTimeout(function(){
                    myWindow.close();
                    $("#iframe").append(iframe);
                },1000);
            } else {
                $("#iframe").append(iframe);
            }
            loaded = true;
        });
    })
</script>
<a class="test" href="#">登录</a>

<div id="iframe"></div>
