javascript - 如何从ajax获取表单ID并在symfony2的点击功能中设置它

Question

我想将 id 存储在全局变量中，然后存储此 id 以进行表单编辑这是我的 xml 请求:

if($request->isXmlHttpRequest()) {
        $response = new Response();
        $output = array('success' => true, 'title' => $entity->gettitle(), 'id' => $entity->getId(), 'notes' => $entity->getnotes(), 'accountid' => $entity->getaccountid(), 'clientid' => $entity->getClientID(), 'status' => $entity->getstatus(), 'totalamount' => $entity->getTotalAmount(), 'paidamount' => $entity->getPaidAmount(), 'balanceamount' => $entity->getBalanceAmount(), 'createdby' => $entity->getcreatedby(), 'updatedby' => $entity->getupdatedby(), 'createddatetime' => $entity->getcreateddatetime(), 'updateddatetime' => $entity->getupdateddatetime());
         $response->headers->set('Content-Type', 'application/json');
         $response->setContent(json_encode($output));
         return $response;
    }

这是我的ajax代码:

$("form").submit(function(e) {              
         e.preventDefault();
         var url = $(this).attr('action');
         var data = $(this).serialize();
         $.ajax({
            type: "POST",
            url: url,
            data: data,
         }).done(function( result ) {
                 invoiceid=result.id;
            if(result.success) {
                $('#result').css({'color':'black','background-color':'#8F8','display':'Block','width':'200px'});
                $('#result').html('Invoices Record Inserted');
                setTimeout(function(){
                    $('#result').hide();
                    },3000);
            }
         });
         this.reset();
     });
     $("#edit").click(function(){

    window.location.href= "{{ path('invoices_edit', {'id': invoiceid }) }}";  
            });      

这是包含 id 的 myjson 响应:

 {"success":true,"title":"invoice","id":57,"notes":"gjgjgjgjg","accountid":1,"clientid":"5","status":"sent","totalamount":"90000","paidamount":"45000","balanceamount":"45000","createdby":1,"updatedby":1,"createddatetime":{"date":"2013-10-03 17:37:00","timezone_type":3,"timezone":"Asia\/Karachi"},"updateddatetime":{"date":"2013-10-03 17:37:00","timezone_type":3,"timezone":"Asia\/Karachi"}}

当我提醒 invoiceid 然后它显示 result.id 的值但 invoiceid 没有传递给点击功能，我该怎么做？

.done() 是回调。

你需要传递result.id或者在done回调中调用$('#edit').click()

<script type="text/javascript">
var invoiceId;
$(document).ready(function(){
 $("form").submit(function(e) {              
         e.preventDefault();
         var url = $(this).attr('action');
         var data = $(this).serialize();
          $.ajax({
            type: "POST",
            url: url,
            data: data,
           })
           .success(function( result ) {
              invoiceid=result.id;
             //after setting you can call click like this
              $('#edit').click(); // or use trigger()
               if(result.success) {
                $('#result').css({'color':'black',
                      'background-color':'#8F8','display':'Block','width':'200px'});
                $('#result').html('Invoices Record Inserted');
                setTimeout(function(){$('#result').hide();},3000);
              }
            });
         this.reset();
     });

   $("#edit").click(function(){
      = "{{ path('invoices_edit', {'id': invoiceid }) }}";
   });

 });

</script>
