Jquery AJAX实时获得新的神秘记录
原标题:Jquery AJAX get new mysql records in real time

是否有任何类似于排泄物的解决办法,以便实时利用PHP来回收新的神秘记录,并使它们滑坡

感谢

类似情况

$(function() {
    setInterval(function() {
        $.ajax({
            type: "GET",

            url: "location/of/server/script.php",
            success: function(html) {
                 // html is a string of all output of the server script.
                $("#element").html(html);
           }

        });
    }, 5000);
});

它将每5秒更新一次。

这只是一个实例,可以在诉讼之后添加效果。 希望会有助于

如果你真的想要实时更新,我会建议你读一下网页。 否则,你就可以使用“间隔”。

,这是最好的

你们可以在网上找到许多研究:

如果你真的想要实时,你会再次要求把通知“放开”给客户,而不是污染。 为此,在客户方面,你可能希望利用诸如“超文本5”等“发明来源”来倾听事件,并更新国际交易日志。

在服务器方面,我的sql没有办法通知新记录,因此你可能希望使用某种信息查询(如RabbitMQ或积极MQ)。 你们必须修改在贵国数据库中插入的代码,以便也能够通知你的信息。
