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>
