我的应用程序包含一个带有内容页面的 Masterpage。Masterpage 包含通过动态选择和扩展节点来操作树视图的 javascript 函数。在一种情况下,我试图通过内容页面上的代码隐藏来调用 Masterpage 上的 javascript 函数,但 javascript 从未被调用。我在 javascript 中放置了断点,但它们永远不会被击中。
需要发生的是,在项目被删除后,内容页面重新加载,同时我需要调用 javascript 函数。
注意:javascript 确实可以作为整个系统中动态构建的链接运行,并且会遇到断点并且函数会运行。
这是我从以下位置调用 javascript 的代码隐藏方法:
Protected Overrides Sub OnDelete(ByVal SelectedItems As System.Collections.Specialized.NameValueCollection)
For i As Integer = 0 To SelectedItems.AllKeys.GetLength(0) - 1
Dim strProjectId As String = SelectedItems.AllKeys(i)
Dim objProject As New BSProject(strProjectId)
BSProject.Delete(Val(strProjectId), Page)
' log action
BSActivity.Log(Page.User.SiteUser.intID, "Project Delete", _
"Project """ & objProject.strProjectName & """ of Organization """ & _
Projects.objOrganization.strName & """ was deleted")
Next
Dim script As ClientScriptManager = Page.ClientScript
script.RegisterStartupScript(GetType(Page), "RefreshProject", "parent.refreshNodeForProjects('" & Projects.objOrganization.intID.ToString() & ":company','" & Projects.objLocation.intID.ToString() & ":location" & "');") ' "parent.refreshNodeForProjects('" & Projects.objOrganization.intID.ToString() & ":company','" & Projects.objLocation.intID.ToString() & ":location" & "');", False)
If BSConfig.GetValue("ProjectsRefresh") = "1" Then
Response.Redirect(Request.RawUrl)
End If
End Sub
这是 MasterPage 上的 javascript 函数:
function refreshNodeForProjects(company, location) {
try {
var tree = $find("<%= radprojecttree.ClientID %>");
if (company != '') {
rootnode = tree.findNodeByValue(company);
rootnode.set_expanded(false);
rootnode.get_treeView().trackChanges();
rootnode.get_nodes().clear();
rootnode.set_expandMode(2);
rootnode.get_treeView().commitChanges();
rootnode.set_selected(true);
rootnode.set_expanded(true);
if (location != '') {
rootnode = GetNodebyValue(rootnode, location);
rootnode.set_expanded(false);
rootnode.get_treeView().trackChanges();
rootnode.get_nodes().clear();
rootnode.set_expandMode(2);
rootnode.get_treeView().commitChanges();
rootnode.set_selected(true);
rootnode.set_expanded(true);
}
scrollToNode(tree, rootnode);
}
}
catch (ex) {
throw ex;
}
}
