Question

javascript變量我有這樣的代碼

<script type = "text/javascript"> 
$(document).ready(function(){ 
    $(".sub_category").click(function() 
    { 
     var main_cat = $("input[name='category_form_cat_1']:checked").val(); 
     var sub_cat_form1 = $("input[name='subcategory_form_cat_1']:checked").val();  
     $("input[name='subcategory_form_cat_1'][value=sub_cat_form1]").attr("checked",true);​ 
     $.ajax 
     ({ 
      data: {'cat':main_cat,'sub_cat':sub_cat_form1}, 
      url: "ajax_files/events-select.php", 
      type: 'GET',     
      success: function(data) 
      { 
       $("#displayedresults").html(data); 
       $('#loading_spinner').hide(); 
       $('#loading_text').hide(); 
       $('#loading_row').hide(); 
       $('#displayedresults').show(); 
       //$('.button_export').show(); 
       //$("a.button_export").attr("href", string); 
      } 
     }); 
     return false; 
    }); 
}); 

我需要這條線的值存儲在未來一

var sub_cat_form1 = $("input[name='subcategory_form_cat_1']:checked").val();  
$("input[name='subcategory_form_cat_1'][value=sub_cat_form1]").attr("checked",true);​

，你可以做這樣的

var sub_cat_form1 = $("input[name='subcategory_form_cat_1']:checked").val();  
    $("input[value="+sub_cat_form1 +"]").attr("checked",true);​
