Question

Hi,

have pasted some script on "page edit" using page editor web part which hide fields succssfully

My Script:

<script type="text/javascript">
SP.SOD.executeOrDelayUntilScriptLoaded(CustomJS, 'sp.js');

function CustomJS() {
$("input[Title='Filename']").prop("disabled", true);
$('nobr:contains("Name")').closest('tr').hide();
$('nobr:contains("Title")').closest('tr').hide();
$('nobr:contains("User")').closest('tr').hide();
$('nobr:contains("Flag")').closest('tr').hide();
$('nobr:contains("status")').closest('tr').hide();

$('nobr:contains("docType")').closest('tr').hide();
$('nobr:contains("ParentdeptID")').closest('tr').hide();
$('nobr:contains("ModifiesStatusDate")').closest('tr').hide();
$('nobr:contains("RespondBy")').closest('tr').hide();
$('nobr:contains("docreason")').closest('tr').hide();
$('nobr:contains("SopIDLevel4")').closest('tr').hide();

}
</script>

Problem: Wheater i login as a admin or contributor all fields are hidden.

 

Solution Required: if i login as a Admin or Site Collection Administrator all fields should be available not hide.
