如何在Symfony2中的Bootstrap模式弹出窗口中动态显示数据 [英] How to display data dynamically in Bootstrap Modal Popup in Symfony2

问题描述

我想在Modal Popup中显示一个编辑表单，其中包含相应ID的信息。换句话说，我想在链接点击的模态弹出窗口中显示数据库中的动态数据。

I want to display an edit form in Modal Popup with the information of respective ID. In other words i want to display the dynamic data from the database in modal popup on the link click.

到目前为止我尝试了什么：
Twig文件哪个有所有数据的列表：

What i have tried so far: Twig file which have list of all the data:

<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>

动态ID传递的jQuery函数：

jQuery function for the dynamic ID pass:

 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控制器功能：

Controller function to edit the data and render the form:

   /**
 * 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态弹出窗口中）：

edit.html.twig file contains the Edit Form (I want this form to display in the modal popup):

{{ form(edit_form) }}

单击EDIT按钮后，它甚至没有显示任何错误

After clicking on the EDIT button, it displays nothing not even any error

注意：我使用 generate：doctrine：crud 命令执行CRUD操作

NOTE: I have used generate:doctrine:crud command to do the CRUD operations

我知道我在流程或jQuery函数或控制器代码中的某个地方滞后，但无法确定确切的冲突。

I know i am lagging somewhere in the flow or the jQuery function or the controller Code, but not able to identifying the exact conflict.

帮帮我，比喻

推荐答案

<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 结构中你有 onclick 事件已处理，如果您看到 editDocument js函数，则：

In the above html structure you have onclick event handled and if you see your editDocument js function then:

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 );
    });
}

你有 $（文件）.on（'点击'... 这是不必要的。我建议使用上面的任何一个。从结构中删除 onclick 并删除你的函数包装围绕 $（文件）.on（'点击'... 或对您的功能进行更改，如下所示：

you have $(document).on('click'... which is unnecessary. I would suggest to use any one of the above. Either remove onclick from structure and remove your function wrapped around $(document).on('click'... or make changes to your function as below:

<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
           }
    });
}

如果您使用的是 $（文件）。 on（'click'.... 然后将其更改如下：

OR if you are using $(document).on('click'.... then change it as below:

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
               }
    });
});

我觉得你不需要锚内的按钮你可以应用
类来锚定自己以获得如下按钮的感觉：

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>
