Question

我已将datapager控件绑定到listview。

我想滚动到DataPager点击列表视图控件的第一项。我认为这应该用javascript完成。似乎数据采集器不允许这样做。

我有哪些选择？单击DataPager时如何滚动到特定锚点？

Answer 1

您可以使用基本的html named anchor滚动到特定的锚点。

Answer 2

您可以在客户端或“服务器端”使用javascript函数 scrollIntoView ： http://www.codeproject.com/KB/aspnet/ViewControl.aspx

谢谢蒂姆！

对于懒惰的人（就像我一样），这里是VB.NET的等价物。它包含拼写错误更正和新的RegisterClientScriptBlock Method

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        FocusControlOnPageLoad("Label1", Me.Page)
 End Sub

 Public Sub FocusControlOnPageLoad(ByVal ClientID As String, ByVal page As System.Web.UI.Page)
        Dim csName As String = "ScrollViewScript"
        Dim csType As Type = Me.GetType
        Dim cs As ClientScriptManager = page.ClientScript
        If Not cs.IsClientScriptBlockRegistered(csType, csName) Then
            Dim csText As New StringBuilder()
            csText.Append("<script>function ScrollView(){")
            csText.Append("var el = document.getElementById('" & ClientID & "');")
            csText.Append("if (el != null){")
            csText.Append("el.scrollIntoView();")
            csText.Append("el.focus();}}")
            csText.Append("window.onload = ScrollView;")
            csText.Append("</script>")
            cs.RegisterClientScriptBlock(csType, csName, csText.ToString())
        End If
    End Sub

如何滚动到锚点？
