Just few jQuery lines of code:

 

Take cell value from DataTables.net:

 $("#myTable").data().oTable.fnGetData(0).

Date Convert string to date using current format:

 $.datepicker.parseDate($.datepicker._defaults.dateFormat, myStringDate)

Increment date:

 date.setDate( date.getDate() + 1 );

To have dialog inside of dialog, then I have to close existing one (at this moment I don’t know if there is possibility to have two modal windows at the same time)

$(this).dialog('close');
dialogs.alertUI("Export confirm", "Are you sure?", myTest, null); 

Delete all single quotes from a string:

myMessage.replace(/'/g, "");
