ajax

    $.ajax(
        type: 'post',
		url: 'https://www.demo.com/?r=demo.php',
		crossDomain:true, //跨域请求为true如果你想强制跨域请求（如JSONP形式）同一域，设置crossDomain为true。这使得例如，服务器端重定向到另一个域。默认为false
        data: form_datas,
        success: function (data) 
            if (data.data!= undefined) 
                alert('1');
            else
                alert('2')
