Question

我有一个场景，我需要在列表中显示带有标题列的Alert横幅。

以下是我尝试使用的代码。但它没有正确显示。任何人都可以让我知道Errorl

<script type="text/ecmascript" language="ecmascript">

    var strStatusID;

    function showInfo(strMessage) {
        alert("Code sucess");
        strStatusID = SP.UI.Status.addStatus(strMessage, true);
        alert(strMessage.toString());
        SP.UI.Status.setStatusPriColor(strStatusID, "yellow");

    }




</script>
<asp:Panel ID="Panel1" runat="server">

<asp:Label ID="lblScripter" runat="server" Visible="false"></asp:Label>

</asp:Panel>


  public void LoadGrid()
        {
            //System.Diagnostics.Debugger.Break();

            var oSPWeb = SPContext.Current.Web;
            SPList oSpList = oSPWeb.Lists["AlertList"];
            SPQuery oQuery = new SPQuery();
            oQuery.Query = @"<Where><Neq><FieldRef Name='NoOfDays' /><Value Type='Calculated'>0:00</Value></Neq></Where>";
            SPListItemCollection _AlertListCollection = oSpList.GetItems(oQuery);
            DataTable Table_Calendar = _AlertListCollection.GetDataTable();

            if (Table_Calendar != null)
            {

                foreach (SPListItem item in _AlertListCollection)
                {

                    MessageShow = item["Title"].ToString();

                }


               // strStatusID = SP.UI.Status.addStatus(strMessage, true);
                lblScripter.Text = "<Script language='javascript;>showInfo('" + MessageShow + "');</script>";
            }


            else
            {
                lblScripter.Visible = false;


            }

                //else

                //    lblScripter.Visible = false;


                //}



            }

Answer 1

尝试设置：

 lblScripter.Text = @"<script type=""text/javascript"">SP.SOD.executeOrDelayUntilScriptLoaded(function() {showInfo('" + MessageShow + "');}, 'sp.js');</script>"

这很可能解决了在加载之前调用SP.UI.Status javascript函数的问题。

我已经解决了这个PFB代码以实现这一目标。感谢我的朋友Hameed帮助我实现了同样的目标

<script type="text/ecmascript" language="ecmascript">

    Sys.WebForms.PageRequestManager.getInstance().add_endRequest(RegisterMethods);
    function RegisterMethods() {
        showInfo();
        RemoveLastStatus();
    }
    function showInfo() {
        var strMessage = document.getElementById('<%= Message.ClientID %>').value;
        var strstatus = document.getElementById('<%= StartStatus.ClientID %>').value;

        if (strMessage != null) {
            if (strstatus != "false") {
                var strStatusID;

                strStatusID = SP.UI.Status.addStatus(strMessage);
                SP.UI.Status.setStatusPriColor(strStatusID, "red");
                document.getElementById('<%= StartStatus.ClientID %>').value = "false";
                document.getElementById('<%= StatusId.ClientID %>').value = strStatusID;

        }


    }
