按钮的OnClientClick事件未起效

Question

JS代码:
<script type="text/javascript">
         function SubNews()
{
var validateSucc;
if (typeof(Page_ClientValidate) == 'function') 
validateSucc = Page_ClientValidate();
if(validateSucc)
{
saving.style.visibility="visible";
cover.style.visibility="visible";
tableCover.height = window.screen.height;
return true;
}
return true;
}

function EndSub()
{
saving.style.visibility="hidden";
cover.style.visibility="hidden";
}
</script>
Html
<asp:ImageButton ID="ibtnPost" OnClick="ibtnPost_Click" runat="server" ImageUrl="images/jlygda_index_01.jpg" OnClientClick="return SubNews();" >
          </asp:ImageButton>
          
          <%--等待提示DIV--%><div id="saving" style="z-index: 10; left: 130px; visibility: hidden; position: absolute;
        top: 800px">
        <table cellspacing="0" cellpadding="0" width="100%" border="0">
            <tr>
                <td width="30%">
                </td>
                <td bgcolor="#acd0f0">
                    <table height="70" cellspacing="2" cellpadding="0" width="100%" border="0">
                        <tr>
                            <td align="center" bgcolor="#eeeeee">
                                正在保存视频, 请稍候...</td>
                        </tr>
                    </table>
                </td>
                <td width="30%">
                </td>
            </tr>
        </table>
    </div>
    <div id="cover" style="z-index: 9; left: 0px; visibility: hidden; position: absolute;
        top: 0px">
        <table id="tableCover" cellspacing="0" cellpadding="0" width="100%" border="0">
            <tr>
                <td align="center">
                    <br>
                </td>
            </tr>
        </table>
    </div>  
C#代码    /// <summary>
    /// 提交
    /// </summary>
    /// <param name="sender"></param>
    /// <param name="e"></param>
    protected void ibtnPost_Click(object sender, ImageClickEventArgs e)
    {
        if (SaveData())
        {
            ScriptManager.RegisterStartupScript(UpdatePanel1, this.GetType(), "StartupKey", "alert('添加视频成功');EndSub();", true);
            Response.Redirect("VideoBackList.aspx?ChannelID=" + Convert.ToString(ViewState["ChannelID"]));
        }
        else
        {
            ScriptManager.RegisterStartupScript(UpdatePanel1, this.GetType(), "StartupKey", "alert('添加视频失败');EndSub();", true);
        }
    }
问题:不显示提示DIV...应该如何修改?

Answer 1

楼主这种写法不行哦!!
ScriptManager.RegisterStartupScript(UpdatePanel1, this.GetType(), "StartupKey", "alert('添加视频成功');EndSub();", true);
Response.Redirect("VideoBackList.aspx?ChannelID=" + Convert.ToString(ViewState["ChannelID"]));这样第一句还没执行完,已经跳到VideoBackList.aspx页面了!!
  

Answer 2

放在标签ScriptManager之外和ajax冲突

Answer 3

嗯..我也发现了...一会儿改一下...我现在想问的是...为什么我的OnClientClick事件没有起效?(没有提示信息的显示)

Answer 4

那我应该怎么做?<cc1:ToolkitScriptManager ID="ToolkitScriptManager1" runat="server" EnableScriptGlobalization="true" EnableScriptLocalization="true"><asp:ImageButton ID="ibtnPost" OnClick="ibtnPost_Click" runat="server" ImageUrl="images/jlygda_index_01.jpg" OnClientClick="return SubNews();" >
          </asp:ImageButton>
</cc1:ToolkitScriptManager>这样?还是?

Answer 5

你的OnClientClick返回的都是true哦!!
返回true就是要回发的,页面刷新了,怎么可能有效果呢??
返回false,才会有效果哦!!

Answer 6

 function SubNews()
    {
        var validateSucc;
        if (typeof(Page_ClientValidate) == 'function') 
        validateSucc = Page_ClientValidate();
        if(validateSucc)
        {
            saving.style.visibility="visible";
            cover.style.visibility="visible";    
            tableCover.height = window.screen.height;
            return true;
        }
        else
        {
            return false;  //没有验证通过时，那么就返回false；这样就不会再进行OnClick事件了。
        }    }
