如何引用动态JQuery HTML标记

Question

有很多类似的问题，但它们都是关于如何编写动态创建的ID标记，而不是现在在尝试使用ID时引用它们。下面，我发布了第一个使用<tr>标记中的SessionId创建带有ID标记的表的函数（请参阅代码注释“这是重要的部分”。

下面我有我希望它做的功能。我试图在单击该行中的按钮后更改表格行中的内容。

我有这个代码创建标签：

$('#lookup').click(function (event) {
        $('#results').html("");
        $('#btn').html("");
        $('#reset').html("");
        strUser = $('#userid').val();
        lookfor = JSON.parse('{ "username":"' + strUser + '" }');
        $.ajax({
            type: "POST",
            url: "/Home/FindUser",
            data: lookfor,
        }).done(function (data) {
            var html = "";
            var err = "";
            var count = 0;
            var elite = false;

            $.each(data, function (entryIndex, entry) {

                if (entryIndex == 0) {
                    html += "<tr>";
                    html += "<th>Username</th>";
                    html += "<th>Server</th>";
                    html += "<th>App</th>";
                    html += "</tr>";
                }
                if (entry.Result) {
                    err = "<tr>";
                    err += "<td>" + entry.Result + "</td>";
                    err += "</tr>";
                } else {  //**This is the important part here**:
                    html += "<tr id=Session" + entry.SessionId + ">";
                    html += "<td><input type=\"hidden\" name=\"sessid\" value=\"" + entry.SessionId + "\" id=\"SessionId\">" + entry.UserId + "</td>";
                    html += "<td><input type=\"hidden\" name=\"sessid\" value=\"" + entry.ServerName + "\" id=\"ServerName\">" + entry.ServerName + "</td>";
                    html += "<td><input type=\"hidden\" name=\"sessid\" value=\"" + entry.AppName + "\" id=\"AppName\">" + entry.AppName + "</td>";
                    html += "<td><a href=\"/Home/Details?SessionId=" + entry.SessionId + "&ServerName=" + entry.ServerName + "\">Details</a></td>";
                    html += "<td><input type=\"submit\" value=\"Log Off\" runat=\"server\" class=\"btn btn-default\" id=\"logoffsession\" /></td>";
                    html += "</tr>";
                }
                if (entry.Elite) {
                    elite = true;
                }
                count++;
            });
            if (err.length > 0) {
                $('#results').append($(err));
            } else {
                $('#results').append($(html));
            }

            if (count > 0) {
                var btn = "<td><input type=\"submit\" value=\"Log Off All Sessions\" runat=\"server\" class=\"btn btn-default\" id=\"logoff\" /></td>";
                $('#reset').append($(btn));
            } else if (elite) {
                var btn = "<td width=\"50\"><input type=\"submit\" value=\"Reset Elite Profile\" runat=\"server\" class=\"btn btn-default\" id=\"resetelite\" /></td>";
                $('#reset').append($(btn));
            } else {

            }
        });
    });

现在这就是我想用它做的事情：

$(document).ready(function () {
        $(document).on("click", "#logoffsession", function (event) {
            var SessionId = $('#SessionId').val();
            var ServerName = $('#ServerName').val();
            var AppName = $('#AppName').val();
            var Pattern = /Elite/;
            var exists = Pattern.test(AppName);
            lookfor = JSON.parse('{ "sessionid":"' + SessionId + '","servername":"' + ServerName + '" }');
            $.ajax({
                type: "POST",
                url: "/Home/LogOffSession",
                data: lookfor,
            }).done(function (data) {
                var html = "<td>" + data.Result + "</td>"

                //**Right here below is what I want to do**:
                $("'#Session" + SessionId + "'").html("");
                $("'#Session" + SessionId + "'").append($(html));
            });
        });
    });

$("'#Session" + SessionId + "'")调用它似乎不起作用。
