I have to call SP search Api for documents in document Library applying filter for only bring such documents which are published and having specific content type .
Is there any specific property for the items in document library which determines whether the document is Published Or not using javascript .
I think what your looking for is this:
using rest
var value = SP.File.get_checkOutType()

Example
$.ajax({url: "/_api/web/getFileByServerRelativeUrl('" + pageUrl + "')/checkOutType", headers: { "Accept": "application/json; odata=verbose" }, success: function(data) { switch(data.d.CheckOutType) { case 0: console.log('The file is checked out for editing on the server.'); break; case 1: console.log('The file is checked out for editing on the local computer.'); break; default: console.log('The file is not checked out.'); } } });
