Select2从上次选择的选择框中检索无效结果

Question

我目前有一个问题，现在我的select2插件有时显示最后选择的选择框的结果。当我第一次点击选择框或者输入太快时，我也会得到g.results有时为空。我的代码如下。

 window.currentField = ""; //current product field data 
     window.currentCategory = ""; //current product category data 

     //lets get some data from the hidden input for providing suggestions via ajax 

     $(".suggestive-entry").live('click',function() { 
      //alert("click called"); 
      //alert("test"); 

      window.currentField = $(this).siblings('input:hidden').attr('data-field'); //get the field attribute 
      // alert(window.currentField); 
      window.currentCategory = $(this).siblings('input:hidden').attr('data-category'); //get the category attribute 
     }); 

     //formats select2 returned option 
     function format(item) { return item.term; }; 

     //used for suggestive search fields 
     $(".suggestive-entry").select2({ 
      createSearchChoice:function(term, data) { if ($(data).filter(function() { return this.term.localeCompare(term)===0; }).length===0) { return {id:term, term:term};} }, 
      initSelection : function (element, callback) { 
       var data = {id: element.val(), term: element.val()}; 
       callback(data); 
      }, 
      multiple: false, 
      ajax: { 
       url: "includes/ajax/map-fields.php", 
       dataType: 'json', 
       data: function (term, page) { 
        //alert("suggestive called"); 
        return { 
         q: term, 
         field: window.currentField, 
         ptype: window.currentCategory 
        }; 
       }, 
       results: function (data, page) { 
        return { results: data }; 
       } 
      }, 

      formatSelection: format, 
      formatResult: format 
     }); 

任何帮助将不胜感激。

尽量给ID你的隐藏字段，这样做

data: function (term, page) { 
     //alert("suggestive called"); 
     var data_field = $('#someId').attr('data-field'); 
     var data_category = $('#someId').attr('data-category'); 
     return { 
       q: term, 
       field: data_field, 
       ptype: data_category 
      }; 
    }
