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"类
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"类
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。
