在我这种情况下，如何使用asp.net中的Cache

我在做一个问卷调查功能，在页面B中有一个Repeater控件，其中嵌套有RadioButtonList控件。在选项中我随意选几个。这时候我会跳转到页面A中，然后再回到页面B。我想要之前选择的几个选项仍然是选定状态。想到要用Cache来做，我没使用过Cache，不知到在这种业务中如何实现？ASP.NETCacheRadiobuttonlistjavascript

解决方案 »

  1.   

    这种不适合用cache 是单个会话，不是整体域的
    适合cookie或session
    你就保存选中项索引或ID标识之类的 加载时判断选中
      

  2.   

    你A页面应该是有保存B页面选择的按钮吧！ 
    那么返回的时候带回B页面的写入记录，在重新绑定。
      

  3.   

    哦 针对单个用户的会话不适合用cache！由于我将选中的数据都在前端js做的，如何写入cookie或session呢？
      

  4.   

    1\可以用层来显示隐藏来表现,这样就不存在cookie或session
    2\用Session记录选项,字符格式如下"1,1,3,5",然后可以用JS设置默认值var checklist="<%= Session["checklist"]==""?"":Session["checklist"].ToString() %>"
    var arycheck=checklist.split(",");
    jQuery(".table1 > tbody > tr").each(function (i, item) {
       jQuery(item).find("input[type='radio'][value='"+ arycheck[i] +"']").attr("checked",true);
       //或者jQuery(item).find("input[type='radio']").eq(arycheck[i]).attr("checked",true);})
      

  5.   

    又是你啊 呵呵！这个功能做的我头疼 tmd！用你这种方式的话，比如我有5个radiobuttonlist，我开始只选其中的两个，这时候arycheck[i] 和 jQuery(item).find 对不上了吧就

    这种方式是可以，不过你没明白我的意思。比方你开始只选了1.1、2.2、3.3这三道题，然后要回到上一页面做些操作，最后返回该页时。session中保存的只有“1.1、2.2、3.3”。这时候如何给对应的radiobuttonlist初始化选定值呢？这时候arycheck[i] 和 jQuery(item).find 对不上了吧就

    在点下一步前就对映好,不选也要留空
    function getCheckID(){
      var checklist="";
      jQuery(".table1 > tbody > tr").each(function (i, item) { 
      if (jQuery(item).find("input[type='radio']:checked").length <= 0){
        checklist+=","
      }
      else{
        checklist+=jQuery(item).find("input[type='radio']:checked").eq(0).val() + ","  }
      });
      jQuery("#hd").val(checklist.substring(0,checklist.length-1))
    }
