我想在回帖后滚动页面。代码在使用/不使用更新面板时无效。
浏览器控制台错误:
未捕获的SyntaxError:意外的令牌< VM465:1
单击VM465:1时,它指向此行:
<script type="text/javascript">$('html, body').animate({ scrollTop: 1600 }, 'slow');</script>
ASPX:
<asp:UpdatePanel ID="up1" runat="server">
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnMore" EventName="Click" />
</Triggers>
<ContentTemplate>
<asp:LinkButton ID="btnMore" runat="server" OnClick="btnMore_Click">ShowMore</asp:LinkButton>
</ContentTemplate>
</asp:UpdatePanel>
C#:
protected void btnMore_Click(object sender, EventArgs e)
{
//string message = "alert('Hello!')";
//ScriptManager.RegisterClientScriptBlock(sender as Control, this.GetType(), "alert", message, true);
ScriptManager.RegisterClientScriptBlock(sender as Control, this.GetType(), "ScrollPage", GetPageScrollScript(900), true);
}
private string GetPageScrollScript(int heightToScroll)
{
string ScrollPage = "<script type=\"text/javascript\">$('html, body').animate({ scrollTop: " + heightToScroll + " }, 'slow');</script>";
return ScrollPage;
}
当我取消注释(没有和没有updatepanel)时,警报会起作用 如何使滚动工作。
更新 它对我有用:
ScriptManager.RegisterClientScriptBlock(sender as System.Web.UI.Control, this.GetType(), "ScrollPage", "$('html, body').animate({ scrollTop: " + 1000 + " }, 'slow')", true);
答案 0 :(得分:1)
您正在使用
之类的提醒alert('Hello!')
这是有效的,但对于你想要执行的脚本,你将它包装在标签
<script type=\"text/javascript\">$('html, body').animate({ scrollTop: " + heightToScroll + " }, 'slow');</script>
没有他们试试?
$('html, body').animate({ scrollTop: " + heightToScroll + " }, 'slow')
