Question

我已成功通过vb生成产品列表作为复选框，并将其添加到<ul>代码

<input type="text" id="searchText" />
<input type="button" value="Search" id="weSearch" />
<div>                                                                                     
 <ul runat="server" id="ulVal" style="list-style-type:none"/></ul>                       
</div>

Dim brandname As String
        Dim brandid As Integer
        Dim build As New StringBuilder()
        Dim msql As New MySqlConnection()
        msql.ConnectionString = "Server=192.168.1.230;Database=cable_tv_reporting1;Uid=root;Pwd=master!!@"
        msql.Open()
        Select Case msql.State
            Case System.Data.ConnectionState.Open

                Exit Select
            Case System.Data.ConnectionState.Closed

                Response.Write("Connection Closed")
                Exit Select
            Case Else
                Exit Select
        End Select
        Dim cmd As New MySqlCommand("select brandID, brandName from cap_brand where isActive=1;", msql)
        Dim reader As MySqlDataReader = cmd.ExecuteReader()
        While reader.Read()
            brandid = Convert.ToInt32(reader(0))
            brandname = reader(1).ToString()
            build.Append("<li><input type='checkbox' name ='brands' id='" & brandid & "' value='" & brandid & "'/><label for='" & brandid & "'>" & brandname & "</label></li>")

        End While
        ulVal.InnerHtml = build.ToString()

问题是jquery没有识别我动态生成的html

$('document').ready(function () {
                                                                                                                    $('#weSearch').on('click', function () {
                                                                                                                        var counted = 0;
                                                                                                                        var boxes = $('#ulVal').find(':checkbox');
                                                                                                                        boxes.each(function () {
                                                                                                                            counted++ ;
                                                                                                                        });
                                                                                                                        alert(counted);
                                                                                                                    });
                                                                                                                });

我得到的结果总是0而不是实际的产品数量。我该如何解决这个问题？

我解决了这个问题，原来我不得不看一下生成的html。由于标签容器，ul的ID正在发生变化。谢谢你的帮助

jquery无法识别动态创建的元素
