javascript - Functions return undefined -

i have getglobaloptionsettextbyvalue function defined in file 1. function returns value. calling function file 2 return value seems set undefined time.

below code file 2:

var x= x|| { __namespace: true }; x.travelhistory = ( function () {     //this function calculate duration , sent error message if duration greater 6 months.     function travelduration( fromdate, todate ) {         var crtldate = xrm.page.getcontrol( todate );         var todate = xrm.page.getattribute( todate ).getvalue();         var fromdate = xrm.page.getattribute( fromdate ).getvalue();         var optionset = xrm.page.getattribute( "dads_javascriptoptionset" );         var notification;         if ( todate != null && fromdate != null ) {             var temp1 = new array();             temp1 = todate.split( '/' ); // split date '/'             var toyear = temp1[0];             var tomonth = temp1[1];              var temp2 = new array();             temp2 = fromdate.split( '/' ); // split date '/'             var fromyear = temp2[0];             var frommonth = temp2[1];             //to year have less year             if ( toyear < fromyear ) {                 //crtldate.setnotification( "to date needs later date." );                 notification = x.common.getglobaloptionsettextbyvalue( 450640028, optionset );                 crtldate.setnotification( notification );              }         }     }     return {         travelduration: function ( fromdate, todate ) {             travelduration( fromdate, todate );         }     }; })(); 

below code file 1:

var x= x|| { __namespace: true }; x.common = ( function () {     var label;     function getglobaloptionsettextbyvalue( value, optionsetlogicalname ) {         var globaloptionset = optionsetlogicalname         var entitylogicalname = xrm.page.data.entity.getentityname();          ( var = 0; < globaloptionset.getoptions().length; i++ ) {             if ( globaloptionset.getoptions()[i].value == value ) {                 label = globaloptionset.getoptions()[i].text;                 break;             }         }         return label;     }     return {         getglobaloptionsettextbyvalue: function(value, optionsetlogicalname) {             getglobaloptionsettextbyvalue(value, optionsetlogicalname);         }     }; })(); 

the problem object returned xrm.page.getattribute( "dads_javascriptoptionset" ); not contain entry value like

{  id: 450640028,  text: "....whatever..." }
