Modal is a child window covering the parent form body. Typically, the purpose is to display content from a separate source that can have some interaction without leaving the parent form. Subforms provide information, interaction, and more.

If you want to reference the functionality of the plugin separately, then you need to reference modal.js. Alternatively, as mentioned in the Bootstrap plugin overview chapter, you can reference bootstrap.js or a minified version of bootstrap.min.js.

Usage

You can switch the hidden content of the modal plug-in:

  • via the data attribute : on a controller element (such as a button or link) Set the attribute data-toggle="modal", and set data-target="#identifier" or href="#identifier" to specify the switch A specific modal (with id="identifier").
  • Via JavaScript: Using this technique, you can call a modal with id="identifier" with a simple line of JavaScript: 
    $('#identifier').modal(options)

    • Example

    A static modal window instance, as shown in the following example: 

    <!DOCTYPE html> <html> <head> <title>Bootstrap 实例 - 模态框（Modal）插件</title> <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet"> <script src="/scripts/jquery.min.js"></script> <script src="/bootstrap/js/bootstrap.min.js"></script> </head> <body> <h2>创建模态框（Modal）</h2> <!-- 按钮触发模态框 --> <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal"> 开始演示模态框 </button> <!-- 模态框（Modal） --> <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true"> &times; </button> <h4 class="modal-title" id="myModalLabel"> 模态框（Modal）标题 </h4> </div> <div class="modal-body"> 在这里添加一些文本 </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">关闭 </button> <button type="button" class="btn btn-primary"> 提交更改 </button> </div> </div><!-- /.modal-content --> </div><!-- /.modal --> </body> </html>

    The result is as follows:

    Code explanation:

  • To use a modal window, you need to have some kind of trigger. You can use buttons or links. Here we are using buttons.
  • If you look carefully at the above code, you will find that in the bb9345e55eb71822850ff156dfde57c8 tag, data-target="#myModal" is the modal you want to load on the page box target. You can create multiple modals on the page and then create different triggers for each modal. Now, obviously, you can't load multiple modules at the same time, but you can create multiple modules on the page that load at different times.
  • You need to pay attention to two points in the modal box:
  • The first is .modal, which is used to identify the content of dc6dce4a544fdca2df29d5ac0ea9906b as a modal box.
  • The second is the .fade class. When the modal is toggled, it causes the content to fade in and out.
  • aria-labelledby="myModalLabel", this attribute refers to the title of the modal box.
  • Attribute aria-hidden="true" is used to keep the modal window invisible until the trigger is fired (such as clicking on the relevant button).
  • 699e085bcbc1be17121184de54cd6b00, modal-header is a class that defines styles for the header of modal windows.
  • class="close", close is a CSS class used to style the close button of a modal window.
  • data-dismiss="modal", is a custom HTML5 data attribute. Here it is used to close the modal window.
  • class="modal-body", is a CSS class of Bootstrap CSS, used to set styles for the body of modal windows.
  • class="modal-footer", is a CSS class of Bootstrap CSS, used to style the bottom of modal windows.
  • data-toggle="modal", HTML5 custom data attribute data-toggle is used to open a modal window.

    • Options

    There are some options that can be used to customize the look and feel of the modal window. They are passed through the data attribute or JavaScript. The following table lists these options:

    Option Name Type/Default Value Data Property Name Description
    backdrop boolean or string 'static '
    Default value: true    		 data-backdrop Specify a static background that will not close the modal box when the user clicks outside the modal box.
    keyboard boolean
    Default value: true    		 data-keyboard When pressed When the escape key is pressed, the modal box is closed. When set to false, the key press has no effect.
    show boolean
    Default value: true    		 data-show When initialized Show modal box.
    remote path
    Default value: false    		 data-remote Use jQuery The .load method injects content into the main body of the modal box. If you add an href with a valid URL, the content within it will be loaded. As shown in the following example: 选项名称 类型/默认值 Data 属性名称 描述
    backdrop boolean 或 string 'static'
    默认值：true    		 data-backdrop 指定一个静态的背景，当用户点击模态框外部时不会关闭模态框。
    keyboard boolean
    默认值：true    		 data-keyboard 当按下 escape 键时关闭模态框，设置为 false 时则按键无效。
    show boolean
    默认值：true    		 data-show 当初始化时显示模态框。
    remote path
    默认值：false    		 data-remote 使用 jQuery .load 方法，为模态框的主体注入内容。如果添加了一个带有有效 URL 的 href，则会加载其中的内容。如下面的实例所示： 
    <a data-toggle="modal" href="remote.html" data-target="#modal">请点击我</a>

    方法

    下面是一些可与 modal() 一起使用的有用的方法。

    方法 描述 实例
    Options: .modal(options) 把内容作为模态框激活。接受一个可选的选项对象。 
    $('#identifier').modal({ keyboard: false })
    Toggle: .modal('toggle') 手动切换模态框。 
    $('#identifier').modal('toggle')
    Show: .modal('show') 手动打开模态框。 
    $('#identifier').modal('show')
    Hide: .modal('hide') 手动隐藏模态框。 
    $('#identifier').modal('hide')

    实例

    下面的实例演示了方法的用法：

    <!DOCTYPE html> <html> <head> <title>Bootstrap 实例 - 模态框（Modal）插件方法</title> <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet"> <script src="/scripts/jquery.min.js"></script> <script src="/bootstrap/js/bootstrap.min.js"></script> </head> <body> <h2>模态框（Modal）插件方法</h2> <!-- 按钮触发模态框 --> <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal"> 开始演示模态框 </button> <!-- 模态框（Modal） --> <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times; </button> <h4 class="modal-title" id="myModalLabel"> 模态框（Modal）标题 </h4> </div> <div class="modal-body"> 按下 ESC 按钮退出。 </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal">关闭 </button> <button type="button" class="btn btn-primary"> 提交更改 </button> </div> </div><!-- /.modal-content --> </div><!-- /.modal-dialog --> </div><!-- /.modal --> <script> $(function () { $('#myModal').modal({ keyboard: true })}); </script> </body> </html>

    结果如下所示：

    只需要点击 ESC 键，模态窗口即会退出。

    事件

    下表列出了模态框中要用到事件。这些事件可在函数中当钩子使用。

    事件 描述 实例
    show.bs.modal 在调用 show 方法后触发。 
    $('#identifier').on('show.bs.modal', function () { // 执行一些动作... })
    shown.bs.modal 当模态框对用户可见时触发（将等待 CSS 过渡效果完成）。 
    $('#identifier').on('shown.bs.modal', function () { // 执行一些动作... })
    hide.bs.modal 当调用 hide 实例方法时触发。 
    $('#identifier').on('hide.bs.modal', function () { // 执行一些动作... })
    hidden.bs.modal 当模态框完全对用户隐藏时触发。 
    $('#identifier').on('hidden.bs.modal', function () { // 执行一些动作... })

    实例

    下面的实例演示了事件的用法：

    <!DOCTYPE html> <html> <head> <title>Bootstrap 实例 - 模态框（Modal）插件事件</title> <link href="/bootstrap/css/bootstrap.min.css" rel="stylesheet"> <script src="/scripts/jquery.min.js"></script> <script src="/bootstrap/js/bootstrap.min.js"></script> </head> <body> <h2>模态框（Modal）插件事件</h2> <!-- 按钮触发模态框 --> <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal"> 开始演示模态框 </button> <!-- 模态框（Modal） --> <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"> <div class="modal-dialog"> <div class="modal-content"> <div class="modal-header"> <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times; </button> <h4 class="modal-title" id="myModalLabel"> 模态框（Modal）标题 </h4> </div> <div class="modal-body"> 点击关闭按钮检查事件功能。 </div> <div class="modal-footer"> <button type="button" class="btn btn-default" data-dismiss="modal"> 关闭 </button> <button type="button" class="btn btn-primary"> 提交更改 </button> </div> </div><!-- /.modal-content --> </div><!-- /.modal-dialog --> </div><!-- /.modal --> <script> $(function () { $('#myModal').modal('hide')})}); </script> <script> $(function () { $('#myModal').on('hide.bs.modal', function () { alert('嘿，我听说您喜欢模态框...');}) }); </script> </body> </html>
