Get ID from a lookup field in DispForm.aspx

[Taylor Scott]

Hi Alex,

When I’m in new or edit, and I want to get the ID of a lookup field I can use
$(‘#dffs_FIN option:selected’).val() or $(‘#dffs_FIN select’).val()

When it’s in dispform.aspx I can’t use this and getFieldValue(fin) only gives me the lookup value not the ID. Is there a simple way to get the ID that I’m just missing?

You can use this snippet to get the ID from a single choice lookup in DispForm:

var lookupId = GetUrlKeyValue("ID",false,jQuery("#dffs_LookupProject .ms-formbody a").attr("href"));
alert(lookupId);

Replace LookupProject with your field internal name.
