javascript - 如何在 Symfony2 的 Bootstrap 模态弹出窗口中动态显示数据

Question

我想在模态弹出窗口中显示一个编辑表单，其中包含相应 ID 的信息。换句话说，我想在链接单击时以模式弹出窗口显示数据库中的动态数据。

到目前为止我已经尝试过:Twig 文件包含所有数据的列表:

<table class="table table-striped table-hover table-bordered"  style="margin-top:30px;" >
            <thead>
            <tr>
                <th>{{ knp_pagination_sortable(entities, '#', 'a.id') }}</th>
                <th {% if entities.isSorted('a.name') %} class="sorted"{% endif %}> {{ knp_pagination_sortable(entities, 'Name', 'a.name') }}</th>
                <th class="hidden-480">Full Address</th>
                <th>Action</th>
            </tr>
            </thead>
            <tbody>
            {% set count = '1' %}
            {% for entity in entities %}
            <tr>
                <td>{{ entity.id }}</td>
                <td>{{ entity.name }}</td>
                <td>{{ entity.address }}</td>

                <td>
                    <a href="#" onclick="editDocument();" data-id="{{ entity.id }}" role="button" data-toggle="modal" class="open-editBox" ><button type="button" class="btn blue">Edit</button></a>
                    {#<a href="{{ path('venue_edit', { 'id': entity.id }) }}">Edit</a>#}
                    <a href="#deleteModle" data-id="{{ entity.id }}" role="button" data-toggle="modal"><button type="button" class="btn blue">Delete</button></a>

                </td>

                {% set count = count + '1' %}
                {% endfor %}
            </tr>



            </tbody>
        </table>

用于动态 ID 传递的 jQuery 函数:

 function editDocument(){
    $(document).on("click", ".open-editBox", function () {
        var editId = $(this).data('id');
        $.ajax({
            type: 'GET',
            url: editId+"/edit",
            //data: {"editId": editId},
            success: function(response){
                // alert($.get());
                $('#editPlayerModel').html(response);
            }
        });
        // alert(editId);
        //$(".modal-body #editId").val( editId );
    });
}

用于编辑数据和呈现表单的 Controller 函数:

   /**
 * Displays a form to edit an existing Venue entity.
 *
 * @Route("/{id}/edit", name="venue_edit")
 * @Method("GET")
 * @Template()
 */
public function editAction($id)
{
    //print_r($id); exit;
    $em = $this->getDoctrine()->getManager();

    $entity = $em->getRepository('JplAdminFunctionBundle:Venue')->find($id);

    if (!$entity) {
        throw $this->createNotFoundException('Unable to find Venue entity.');
    }

    $editForm = $this->createEditForm($entity);
    $deleteForm = $this->createDeleteForm($id);

    return array(
        'entity'      => $entity,
        'edit_form'   => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    );
}

edit.html.twig 文件包含编辑表单(我希望此表单显示在模式弹出窗口中):

{{ form(edit_form) }}

单击“编辑”按钮后，它不显示任何内容，甚至没有任何错误

注意:我使用了generate:doctrine:crud命令来执行CRUD操作

我知道我在流程、jQuery 函数或 Controller 代码中的某个地方滞后，但无法识别确切的冲突。

帮帮我，谢谢

<a href="#" onclick="editDocument();" data-id="{{ entity.id }}" role="button" data-toggle="modal" class="open-editBox" ><button type="button" class="btn blue">Edit</button></a>

在上面的 html 结构中，您处理了 onclick 事件，如果您看到 editDocument js 函数，则:

function editDocument(){
    $(document).on("click", ".open-editBox", function () {
        var editId = $(this).data('id');
        $.ajax({
            type: 'GET',
            url: editId+"/edit",
            //data: {"editId": editId},
            success: function(response){
                // alert($.get());
                $('#editPlayerModel').html(response);
            }
        });
        // alert(editId);
        //$(".modal-body #editId").val( editId );
    });
}

您有 $(document).on('click'... ，这是不必要的。我建议使用上述任何一项。要么删除 onclick从结构中删除包含 $(document).on('click'... 的函数，或对函数进行如下更改:

<a href="#" onclick="editDocument(this);" data-id="{{ entity.id }}" role="button" class="open-editBox" ><button type="button" class="btn blue">Edit</button></a>

JS

function editDocument(ctrl){ //pass this ctrl from html
    var editId = $(ctrl).data('id');
    var res="";//store the obtained result
    var success=false; //open modal only if success=true
    //url should match your server function so I will assign url as below:
    var url="/editAction"; //this is the server function you are calling
    var data=JSON.stringify({"id":editId});
    $.when( //To execute some other functionality once ajax call is done
    $.ajax({
        type: 'GET',
        url: url,
        dataType:'json',//type of data you are returning from server
        data: data, //better to pass it with data
        success: function(response){
             res=response;
             success=true;
        },
        error:function(){
           //handle error
        },
    })).then(function(){
           if(success)
           {
               //assign each values obtained from response which is now 
               //stored in "res" inside modal element by mapping it to 
               //necessary controls in modal
               $("yourmodalid").modal("show"); //show the modal
           }
    });
}

或者，如果您使用的是 $(document).on('click'....，则按如下方式进行更改:

HTML

<a href="#" data-id="{{ entity.id }}" role="button" class="open-editBox" ><button type="button" class="btn blue">Edit</button></a>

JS

$(document).on("click", ".open-editBox", function () {
    var editId = $(this).data('id'); //get the id with this
    var res="";//store the obtained result
    var success=false; //open modal only if success=true
    //url should match your server function so I will assign url as below:
    var url="/editAction"; //this is the server function you are calling
    var data=JSON.stringify({"id":editId});
    $.when(
        $.ajax({ //To execute some other functionality once ajax call is done
            type: 'GET',
            url: url,
            data: data, //better to pass it with data
            dataType:'json',//type of data you are returning from server
            success: function(response){
                 res=response;
                 success=true;
            },
            error:function(){
               //handle error
            },
        })).then(function(){
               if(success)
               {
                   //assign each values obtained from response which is now 
                   //stored in "res" inside modal element by mapping it to 
                   //necessary controls in modal
                   $("yourmodalid").modal("show"); //show the modal
               }
    });
});

I feel you don't need button inside anchor and you can just apply classes to anchor itself to get button feeling as below:

<a href="#" data-id="{{ entity.id }}" role="button" class="open-editBox btn blue">EDIT</a>

Have a eye on this. Let me know if you face any issues
