$("#show").click(function() { 
    var n = getDivElements();
    alert(n);
});

 function getDivElements() {
 var degisken=""; 
    $('.column').each(function() {
      degisken+=this.id+"="; var j=0;   
     var eachsize=$('#'+this.id).children().size(); 
     $('#'+this.id).children().each(function() {
         degisken+=this.id; j++;
         (j <= (eachsize-1)) ? degisken+="-" : degisken;
      });degisken+=",";
});
 return degisken=degisken.substring(0, degisken.length - 1);
 }

Sonuç: column1=item1-item2,column2=item3-item4,column3=item5-item6
