Adding Javascript to a SharePoint Master or Layout page

If you need to add javascript to a SharePoint Master or Layout page, add the script to the Head section or PlaceHolderAdditionalHead content area. Be sure to include the  _spBodyOnLoadFunctionNames.push function so your function is added to the OnLoad method.

<script type="text/javascript">

function UpdateCampusAddress()

{

if (window.location.href.toLowerCase().startsWith("http://<site name>/"))

{

document.getElementById('CampusAddress').innerHTML = "Williams Campus";

}

else if (window.location.href.toLowerCase().startsWith("http://<site name>/"))

{

document.getElementById('CampusAddress').innerHTML = "Sun Lakes Campus";

}

}

_spBodyOnLoadFunctionNames.push("UpdateCampusAddress");

</script>

Empty dataset template for DataList control

There is no Empty dataset Template for the DataList control. To display a message in the DataList control if your dataset is empty, define a HeaderTemplate and set the visibility based upon the item count as shown below:

 

<asp:DataList runat="server" id="DataList1" DataSourceID="spDataSource1">

<HeaderTemplate>

<span style="font-style:italic;color:#181818">

<asp:Label ID="lblEmpty" Text="No Events" runat="server" Visible='<%# DataList1.Items.Count==0 %>'/>

</span>

</HeaderTemplate>

<ItemTemplate>

<p>

...

</p>

</ItemTemplate>

</asp:DataList>
