    for ( var i= 0; i < arrLen ; i++){  
        var  w = m[i];                     
         if (w.checked){  
          arrAn.push( { "myVal" : w.value } );  
          console.log(w.value ); 
        }  
      }   
    
    var myJsonString = JSON.stringify(arrAn);  //convert javascript array to JSON string
    console.log( 'result' + myJsonString);
