如何使用 bootstrap modal 编辑 MVC 中的表格数据？

Question

我在 MVC 视图中有一个显示员工详细信息的表。我想添加一个编辑功能，但我不想在新页面中打开它，而是想使用引导模式显示它。 (http://twitter.github.com/bootstrap/javascript.html#modals)

我认为我不必使用 ajax，因为数据已经在页面上可用。我想我需要一些 jquery 或 razor 代码将所选员工的数据传递给引导模式，并在同一屏幕上弹出它。下面是我的代码。任何帮助将不胜感激。谢谢

@Foreach(var item in Model.Employees)
{
<tr>
   <td>@User.Identity.Name
            </td>
            <td>@item.FirstName
            </td>....other columns
<td><a href="#myModal" role="button" class="btn" data-toggle="modal">Edit</a>
    <td>
    </tr>........other rows
}
**Bootstrap Modal**


<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
    <h3 id="myModalLabel">Edit Employee</h3>
  </div>

  <div class="modal-body">
    <p>Selected Employee details go here with textbox, dropdown, etc...</p>
  </div>

  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
    <button class="btn btn-primary">Save changes</button>
  </div>
</div>

确实有两种可能性：有或没有 AJAX。如果你想在没有 AJAX 的情况下这样做，你可以订阅 Edit 链接的 click 事件，然后将值从表复制到模态，最后显示模态。

所以首先给你的编辑链接一些类：

<a href="#" class="btn edit">Edit</a>

您可以订阅：

$('a.edit').on('click', function() {
    var myModal = $('#myModal');

    // now get the values from the table
    var firstName = $(this).closest('tr').find('td.firstName').html();
    var lastName = $(this).closest('tr').find('td.lastName').html();
    ....

    // and set them in the modal:
    $('.firstName', myModal).val(firstName);
    $('.lastNameName', myModal).val(lastName);
    ....

    // and finally show the modal
    myModal.modal({ show: true });

    return false;
});

这假设您已为 <td> 元素和模态框中的输入字段提供了适当的 CSS 类。

如果你想使用 AJAX，你可以像这样生成链接：

@Html.ActionLink("Edit", "Edit", "Employees", new { id = employee.Id }, new { @class = "btn edit" })

然后你订阅这个按钮的点击事件并触发AJAX请求：

$('a.edit').on('click', function() {
    $.ajax({
        url: this.href,
        type: 'GET',
        cache: false,
        success: function(result) {
            $('#myModal').html(result).find('.modal').modal({
                show: true
            });
        }
    });

    return false;
});

您将在主视图中有一个简单的模态占位符，其中包含详细信息：

<div id="myModal"></div>

将被命中的控制器操作应该使用 id 获取员工记录并将其传递给部分视图：

public ActionResult Edit(int id)
{
    Employee employee = repository.Get(id);
    EmployeeViewModel model = Mapper.Map<Employee, EmployeeViewModel>(employee);
    return PartialView(model);
}

最后是相应的部分：

@model EmployeeViewModel

<div class="modal hide fade">
    <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
        <h3>Edit Employee</h3>
    </div>
    <div class="modal-body">
        <div>
            @Html.LabelFor(x => x.FirstName)
            @Html.EditorFor(x => x.FirstName)
        </div>
        <div>
            @Html.LabelFor(x => x.LastName)
            @Html.EditorFor(x => x.LastName)
        </div>
        ...
    </div>
    <div class="modal-footer">
        <a href="#" class="btn btn-primary" data-dismiss="modal">Close</a>
        <button class="btn btn-primary">Save changes</button>
    </div>
</div>

显然，您还需要将输入字段包装到 Html.BeginForm 中，这样您就可以将更新后的员工详细信息发送到服务器。如果您想留在同一页面上，可能还需要对此表单进行 AJAX 化。
