Question

根据 jro 的建议，我正在修改我的问题和问题。

==的网址 ==

url('^$','pMass.views.index', name='index')  #Index is the main view with form input type text and submit
                                             #If search value is match then it will render result.html template

== 查看 ==

#View will find search value and render result.html template if request is not ajax
#If request is ajax then same view will create new queryset and render to same template page (result.html) 

 def index(request):
    error = False
    cid = request.GET

    if 'cnum' in request.GET:
       cid = request.GET['cnum']

    if not cid:
       error = False
       expcount = Experiment.objects.count()
       allmass = SelectedIon.objects.count()

   if request.is_ajax():
       value = request.GET.get('value')
       if value is None:
           result = SelectedIon.objects.filter(monoiso__iexact=value).select_related()
           template = 'result.html'
           data = {
               'results':result,
           }
           return render_to_response(template, data,           
          context_instance=RequestContext(request))

    else:

       defmass = 0.000001
       massvalue = float(cid)
       masscon = defmass * massvalue
       highrange = massvalue + masscon
       lowrange = massvalue - masscon

       myquery = SelectedIon.objects.select_related().filter(monoiso__range=(lowrange, highrange))
       querycount = myquery.count()

       return render_to_response('result.html', {'query': cid, 'high':highrange, 'low':lowrange, 'sections':myquery, 'qcount':querycount, })

   return render_to_response('index.html', {'error': error, 'exp': expcount,'mass':allmass,})

==的 result.html ==

# I have divided template into two container: main (left) & container (right)
# Left container is for search match (e.g value/title) with hyperlink
# Right container is for detail of the match value
# For right container I have created jQuery tabs (tab1, tab2, tab3)
# The content of the right container in the tab will update according to the link in the left.
#Layout is given below

               ! tab1  ! tab2 ! tab3 !            
-------------------------------------------------------------------------               
!  434.4456    !  Show Default Match 1 Record                           !
!  434.4245    !  &  left hyperlink onclick show it's value record      !
!  434.4270    !  detail. I have design tab with JQuery                 !

-------------------------------------------------------------------------

== 左容器（result.html）==

#I am looping through the queryset/list of values that was match with template for tag
#The template variable is given a hyperlink so after clicking it's detail information 
 will be shown on right container

<script type="text/javascript" src="/media/jquery-1.2.6.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
    $('#a.id').click(function(){
        value = $ ('a.id').val();
        $('div#tab_content')empty().load('{%url index%}?query'= +value);
        });
    });

<div id="main">
     <table align="center" cellspacing="0" cellpadding="4" border="1" bordercolor="#996600">
          <tr>
              <th>Match</th>
          </tr>     
               {% for section in sections %}
          <tr>
              <td><a href="#" id="{{%section.monoiso%}}">{{section.monoiso}}</a></td>
          </tr>
               {% endfor %}
       </table>
</div>

==的问题 ==

我不知道如何获取超链接值！
超链接（左侧容器）上的jQuery ajax请求无法正常工作
我不确定从 result.html 加载索引视图是否正确
我使用<a href.... id="{{%section.monoiso%}}"从超链接向服务器发送数据，如何在索引视图中使用相同的 id值进行查询，并在result.html？
如何在正确的容器中呈现响应？

建议，评论和回答表示赞赏。

一些起点。首先，您通过Ajax调用的视图不一定要返回一个json对象：数据也可以使用django.http.HttpResponse（或render_to_response作为字符串返回，归结为同样的事情）。这意味着您也可以像往常一样返回完全生成的模板。

假设您的发布视图位于/index/(?<tab>\d+)/(?<match>\d+)/（tab是标签索引，match是匹配索引），您的javascript可能如下所示：

$("ul.tabs li").click(function() {
    $("ul.tabs li").removeClass("active");     // Remove any "active" class
    $(this).addClass("active");                // Add "active" class to this tab
    $(".tab_content").hide();                  // Hide all tab content

    // Construct the url based on the current index
    match_name = $("ul.match li").index($("ul.match li.active"));
    url = "/index/" + $("ul.tabs li").index($(this)) + "/" + match_name + "/";

    // Asynchronous ajax call to 'url'
    new $.ajax({
        url: url,
        async: true,
        // The function below will be reached when the request has completed
        success: function(transport)
        {
            $(".tab_content").html(transport); // Put data in the div
            $(".tab_content").fadeIn();        // Fade in the active content
        }
    });
});

我没有对此进行测试，但沿着这些方向应该做的事情。请注意，为了使用当前代码，您需要查看index函数以允许参数。如果您只想针对每个标签使用相同的网页对其进行测试，请将网址设为：url = "/index/";，以便最有可能立即生效。
