jQuery Ajax response

Question

This is the way I handle an Ajax response. I am sure it can be improved.

success: function (json) { 
 $.each(json, function(index,item){ 
 if (item.field == "article_id") {
 $("#article_id").val(item.value);
 } else if (item.field == "naslov") {
 $("#naslov").val(stripslashes(item.value));
 }else if (item.field == "slug_naslov") {
 $("#slug_naslov").val(item.value);
 }else if (item.field == "datum") {
 $("#datum").val(item.value);
 }else if (item.field == "url") {
 $("#url").val(item.value);
 }else if (item.field == "tekst") {
 $("#tekst").val(stripslashes(item.value));
 }else if (item.field == "tag_title") { //handle tags - tokeninput 
 var tagoviArray = item.value; 
 var tagoviInput = $("#txtTags"); 
 $(tagoviInput).tokenInput("clear");
 $.each(tagoviArray, function (index, value) { 
 var arr = value.split(','); 
 $.each(arr, function (i, v) { 
 if (!(v=="")) { 
 $(tagoviInput).tokenInput("add", {id: "", name: v}); tag
 }
 }); 
 });
 }else if (item.field == "love") {
 $("#love").val(item.value);
 } 
 });
 return false;
 }

Maybe something like this?

success: function (json) {
 var decorators = {},
 handlers = {};
 // decorators prepare content for insertion
 decorators.naslov = stripslashes;
 decorators.tekst = stripslashes;
 // specialized handlers
 handlers.tag_title = function (value) {
 // do the tokenization-stuff here
 };
 // Go through the response
 $.each(json, function (index, item) {
 var value = item.value;
 // if the field has its own handler, use that
 if( typeof handlers[item.field] === "function" ) {
 handlers[item.field](value);
 } else {
 // Otherwise, send the value through the decorator
 // (if there is one for the given field), and
 // insert the value in the corresponding input
 if( typeof decorators[item.field] === 'function' ) {
 value = decorators[item.field](value);
 }
 $("#" + item.field).val(value);
 }
 });
}
