我创建了一个 Web 部件，在 sharePoint 2010 中自定义了可以展开和折叠（+ 和 -）的快速午餐，问题是当网站加载时，快速午餐的默认值已展开，我希望它是崩溃了，我不知道该怎么做 你能帮帮我吗？
第一个代码是用于用户控件的 c# 代码
using System;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Navigation;
namespace QuickLaunchWebpart.Quicklaunch_Webpart
{
public partial class Quicklaunch_WebpartUserControl : UserControl

private void LoadQuickLauchDesign()
{
try
{

{
using (SPWeb web = site.OpenWeb(WebID))
{
SPUser oUser = SPContext.Current.Web.CurrentUser;
SPNavigationNodeCollection nodecoll = web.Navigation.QuickLaunch;
foreach (SPNavigationNode node in nodecoll)
{
TableRow tr = new TableRow();
TableCell cell = new TableCell();
cell.Style.Add("padding-bottom", "15px");
Table innerTable = new Table();
innerTable.CellPadding = 0;
innerTable.CellSpacing = 0;
// innerTable.BorderWidth = 1;
innerTable.Style.Add("width", "100%");
TableRow innerTrTitle = new TableRow();
innerTrTitle.Attributes.Add("onclick", "category_click()");
TableCell innerCellTitle = new TableCell();
innerCellTitle.CssClass = "category";

foreach (SPNavigationNode childnode in node.Children)
{
childTable.Rows.Add(ChildTableRow(childnode.Title, childnode.Url));
}
div.Controls.Add(childTable);
TableRow innerTrLinks = new TableRow();
innerTrLinks.Visible = true;
TableCell innerCellLinks = new TableCell();

innerTrLinks.Cells.Add(innerCellLinks);
innerTable.Rows.Add(innerTrLinks);
cell.Controls.Add(innerTable);
tr.Cells.Add(cell);
tbl1.Rows.Add(tr);
}
}
}
});
}
catch (Exception ex)
{
lblError.Text = ex.StackTrace;
lblError.Visible = true;
}
}
private TableRow ChildTableRow(string title, string Url)
{
TableRow tr = new TableRow();
tr.Height = 20;
TableCell cell = new TableCell();
HyperLink link = new HyperLink();
link.Text = title;
link.NavigateUrl = Url;
link.Attributes.Add("quick_link", "true");
link.Style.Add("display", "block");
cell.Controls.Add(link);
tr.Cells.Add(cell);
if (Request.Url.ToString().Contains(Url) && !(Request.Url.ToString().Contains("/SitePages/Home.aspx")))
{
tr.Attributes.Add("current", "true");
link.Attributes.Add("current", "true");
}
return tr;
}
protected void Page_Load(object sender, EventArgs e)
{
LoadQuickLauchDesign();
}
}
}
以下代码用于用户控件中使用的 java 脚本
<script type="text/javascript">
function category_click() {
var evtSource = event.srcElement + '';
var innerTblRef = null;
if (evtSource == '[object HTMLTableCellElement]') {
innerTblRef = event.srcElement.parentElement.parentElement;
} else if (evtSource == '[object HTMLSpanElement]' || evtSource == '[object HTMLImageElement]') {
innerTblRef = event.srcElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement.parentElement;
}
//Locating the Collapse Image icon
var imgRef = innerTblRef.rows[0].cells[0].firstChild.rows[0].cells[0].firstChild
if (innerTblRef.rows[1].style.visibility == 'visible' || innerTblRef.rows[1].style.visibility == '') {
innerTblRef.rows[1].style.visibility = 'hidden';
innerTblRef.rows[1].style.display = 'none';
imgRef.src = "/_layouts/images/MDNCollapsed.png";
} else {
innerTblRef.rows[1].style.visibility = 'visible';
innerTblRef.rows[1].style.display = 'block';
imgRef.src = "/_layouts/images/MDNExpanded.png";
}
}
function link_hover() {
var cellRef = event.srcElement;
cellRef.className = "link_hover";
if (cellRef + '' == '[object HTMLTableCellElement]') { //Cell hover
cellRef.firstChild.className = "link_hover";
} else { // Image hover
cellRef.parentElement.className = "link_hover";
}
}
function link_hout() {
var cellRef = event.srcElement;
cellRef.className = "link_hout";
if (cellRef + '' == '[object HTMLTableCellElement]') { //Cell hover
cellRef.firstChild.className = "link_hout";
} else { // Image hover
cellRef.parentElement.className = "link_hout";
}
}
</script>
你能帮帮我吗
