全部。我构建了一个运行良好的简单 jQuery/PHP 聊天程序。但是，我想添加 channel 或房间等功能。理想情况下，我想使用聊天顶部的选项卡来管理用户所在的房间(只有 2 个)。我认为这将是一项简单的任务，并且我以前见过类似的事情，但是当单击选项卡时我一直收到未捕获的异常错误，并且源代码没有正确加载。我将发布整个聊天系统的代码，因为我觉得问题可能出在其中。

jquery

page = {
    getChat: function() {
        $.ajax({
            url: 'game_src.php',
            data: 'mode=getChat',
            dataType: 'html',
            cache: false,
            success: function(res){
                $("#chatbox").html(res);
            }
        });
    }
};

$("#submitmsg").click(function(){
    var clientmsg = $("#usermsg").val();
    $.ajax({
        url : 'game_src.php',
        data: 'mode=chatSubmit&msg=' + encodeURIComponent(clientmsg)
    });
    $("#usermsg").attr("value", "");
    return false;
});

setInterval(page.getChat, 4000);

$("#chatChannel").tabs({
    cookie: { expires: 1 },
});

我将向 getChat jquery 函数添加一个参数来来回切换，但是我所拥有的东西让我卡住了。谁能指出我正确的方向？

最佳答案

JQuery UI 选项卡插件期望内容 div 与链接的 ul 位于同一容器中。

在您的例子中，它希望内容 div 位于 ul 正下方的 div id="chatChannel" 中，但是他们不在那里。
