javascript - 在 TreeView 中选择父节点时如何选择所有子节点？ (当从用户控件使用 TreeView 时)

转载作者：行者123 更新时间：2023-11-28 02:13:46

我有一个只有 Treeview 控件的用户控件。

<asp:TreeView ID="Tree_Index" 
Style="font-size: 11px; font-family: Tahoma; font-weight: bold; text-align: left;" runat="server" Width="10px" 
EnableClientScript="False" ShowCheckBoxes="All" ShowLines="True">
</asp:TreeView>

在我的 aspx 页面中，我多次使用此用户控件，以便在我的 aspx 页面中显示具有不同数据的多个 TreeView 。

我像下面这样调用用户控件

Public Sub PopulateTreeview() 
        Dim cph As ContentPlaceHolder = CType(Me.Master.FindControl("cphMain"), ContentPlaceHolder)
    Dim Treeview_Control As Controls_Deot_treecontrol

        Dim ds As DataSet = SPServiceModel.GetAllServiceCategorizationTypes()
        Dim dtRight As DataTable = ds.Tables(0) 

        For i As Integer = 0 To dtRight.Rows.Count - 1
        Treeview_Control = CType(LoadControl("Deot/treecontrol.ascx"), Controls_Deot_treecontrol)
        Treeview_Control.ID = "Treecontrol_Right_" + i.ToString()
        Treeview_Control.SetCategoryID(dtRight.Rows(i)("id").ToString())
            cph.FindControl("pnl_right").Controls.Add(Treeview_Control)
        Next 
End Sub

假设我的 aspx 页面上有 6 个 TreeView 。我想在选择父节点时选择父节点的所有子节点。 TreeView 将具有三层节点。因此，应该为该特定树选择父节点内的所有节点。

我该如何实现这一点，因为ID是我在aspx页面中设置的。我如何使用 javascript 或 jquery 或用户控件的代码隐藏来实现此目的？

渲染的 HTML:

<div id="ctl00_cphMain_pnl_left">



     <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.5.js"></script>

        $(document).ready(function () {
            $("div[id $= Tree_Index] input[type=checkbox]").click(function () {
                $(this).closest("table").next("div").find("input[type=checkbox]").attr("checked", this.checked);
            });
        });
    </script>

最佳答案

您可以简单地使用此代码

$(document).ready(function() {
    $("div[id $= Tree_Index]").find("input[type=checkbox]:first").click(function() {
        $(this).closest("div").find(':checkbox').attr('checked', this.checked);
    });
});
