登陆屏

Framework7支持登陆屏布局,它可以用在页面内部,或者用在弹出框中(嵌入),或者用作单独的遮罩。

登陆屏布局

首先,我们看一下单独的登录屏布局,它和弹出框很像:

<body>
  ...
  <!-- Should be a direct child of BODY -->
  <div class="login-screen">
      <!-- Default view-page layout -->
      <div class="view">
        <div class="page">
          <!-- page-content has additional login-screen content -->
          <div class="page-content login-screen-content">
            <div class="login-screen-title">My App</div>
            <!-- Login form -->
            <form>
              <div class="list-block">
                <ul>
                  <li class="item-content">
                    <div class="item-inner">
                      <div class="item-title label">Username</div>
                      <div class="item-input">
                        <input type="text" name="username" placeholder="Username">
                      </div>
                    </div>
                  </li>
                  <li class="item-content">
                    <div class="item-inner">
                      <div class="item-title label">Password</div>
                      <div class="item-input">
                        <input type="password" name="password" placeholder="Password">
                      </div>
                    </div>
                  </li>
                </ul>
              </div>
              <div class="list-block">
                <ul>
                  <li>
                    <a href="#" class="item-link list-button">Sign In</a>
                  </li>
                </ul>
                <div class="list-block-labe">Some text with login information.</div>
              </div>
            </form>
          </div>
        </div>
      </div>
  </div>
</body>

注意,你在<div class="login-screen">内部看到的元素都是可选的,但是你可以把它们作为你登陆表单的样板

打开和关闭登录屏

使用HTML

可以通过在链接上添加特定的类来打开关闭登陆屏

  • 为了打开登录屏,我们需要在HTML元素(最好是链接)上添加"open-login-screen"

  • 为了关闭登录屏,我们需要在HTML元素(最好是链接)上添加"close-login-screen"

下面是示例:

<body>
  ...
    <div class="page-content">
      <div class="content-block">
        <p><a href="#" class="open-login-screen">Open Login Screen</a></p>
      </div>
    </div>
  ...
  <div class="login-screen">
    <div class="view">
      <div class="page">
        <div class="page-content login-screen-content">
          <div class="login-screen-title">My App</div>
          <form>
            <div class="list-block">
              <ul>
                <li class="item-content">
                  <div class="item-inner">
                    <div class="item-title label">Username</div>
                    <div class="item-input">
                      <input type="text" name="username" placeholder="Your username">
                    </div>
                  </div>
                </li>
                <li class="item-content">
                  <div class="item-inner">
                    <div class="item-title label">Password</div>
                    <div class="item-input">
                      <input type="password" name="password" placeholder="Your password">
                    </div>
                  </div>
                </li>
              </ul>
            </div>
            <div class="list-block">
              <ul>
                <li><a href="#" class="item-link list-button">Sign In</a></li>
              </ul>
              <div class="list-block-label">
                <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
                <p><a href="#" class="close-login-screen">Close Login Screen</a></p>
              </div>
            </div>
          </form>
        </div>
      </div>
    </div>
  </div>
  ...
</body>

使用JavaScript

我们可以通过JavaScript来打开关闭登陆屏,先来看一下相关的App方法:

myApp.loginScreen() - 打开登录屏

myApp.closeModal(loginScreen) - 关闭登录屏

  • loginScreen - HTML元素或是(含有CSS选择器的)字符串。可选。如果没有指定,任何打开的登陆屏/弹出框/模态框都会被关闭。
<body>
  ...
    <div class="page-content">
      <div class="content-block">
        <p><a href="#" class="open-login">Open Login Screen</a></p>
      </div>
    </div>
  ...
  <div class="login-screen">
    ... login screen content ...
  </div>
  ...
</body>
var myApp = new Framework7();
 
var $$ = Dom7;
 
$$('.open-login').on('click', function () {
  myApp.loginScreen();
});

登陆屏事件

登陆屏具有和Modal一样的事件,当你需要在登陆屏打开/关闭时执行操作的时候,它们会有用处。

事件 对象 描述
open 登陆屏元素<div class="login-screen"> 当登陆屏开始弹出动画的时候,事件触发
opened 登陆屏元素<div class="login-screen"> 当登陆屏完成弹出动画的时候,事件触发
close 登陆屏元素<div class="login-screen"> 当登陆屏开始结束动画的时候,事件触发
closed 登陆屏元素<div class="login-screen"> 当登陆屏完成结束动画的时候,事件触发

从登陆屏开启应用

很多时候,我们需要把登陆屏作为应用的第一个页面。为了使它在加载时可见,我们只需要对登陆屏遮罩添加"modal-in"类:

<body>
  ...
  <div class="login-screen modal-in">
    ... login screen content ...
  </div>
</body>

嵌入式登陆屏

也可以把登陆屏嵌入到页面或弹出框中。我们来看一下页面内登陆屏的示例:

index page:

<div data-page="home" class="page navbar-fixed">
  <div class="navbar">
    <div class="navbar-inner">
      <div class="left"></div>
      <div class="center">Embedded Login Screen</div>
      <div class="right"></div>
    </div>
  </div>
  <div class="page-content">
    <div class="content-block">
      <p><a href="login-screen-page.html" class="open-login-screen">Open page with Login Screen</a></p>
    </div>
  </div>
</div>

login-screen-page.html:

<div data-page="login-screen" class="page no-navbar no-toolbar no-swipeback">
  <div class="page-content login-screen-content">
    <div class="login-screen-title">My App</div>
    <form>
      <div class="list-block">
        <ul>
          <li class="item-content">
            <div class="item-inner">
              <div class="item-title label">Username</div>
              <div class="item-input">
                <input type="text" name="username" placeholder="Your username"/>
              </div>
            </div>
          </li>
          <li class="item-content">
            <div class="item-inner">
              <div class="item-title label">Password</div>
              <div class="item-input">
                <input type="password" name="password" placeholder="Your password"/>
              </div>
            </div>
          </li>
        </ul>
      </div>
      <div class="list-block">
        <ul>
          <li><a href="#" class="item-link list-button">Sign In</a></li>
        </ul>
        <div class="list-block-label">
          <p>Click Sign In to close Login Screen</p>
        </div>
      </div>
    </form>
  </div>
</div>   

my-app.js

var myApp = new Framework7();
var $$ = Dom7;
 
var mainView = myApp.addView('.view-main');
 
myApp.onPageInit('login-screen', function (page) {
  var pageContainer = $$(page.container);
  pageContainer.find('.list-button').on('click', function () {
    var username = pageContainer.find('input[name="username"]').val();
    var password = pageContainer.find('input[name="password"]').val();
    // Handle username and password
    myApp.alert('Username: ' + username + ', Password: ' + password, function () {
      mainView.goBack();
    });
  });
});     

注意,在登陆屏上我们有额外的"no-navbar","no-toolbar"和"no-swipeback"类,用来向用户隐藏导航元素。
