例子 (Example)
以下示例演示了Framework7中禁用元素的使用 -
<!DOCTYPE html>
<html>
<head>
<meta name = "viewport" content = "width = device-width, initial-scale = 1,
maximum-scale = 1, minimum-scale = 1, user-scalable = no, minimal-ui" />
<meta name = "apple-mobile-web-app-capable" content = "yes" />
<meta name = "apple-mobile-web-app-status-bar-style" content = "black" />
<title>Checkboxes group</title>
<link rel = "stylesheet"
href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.min.css" />
<link rel = "stylesheet"
href = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/css/framework7.ios.colors.min.css" />
</head>
<body>
<div class = "views">
<div class = "view view-main">
<div class = "pages">
<div data-page = "home" class = "page navbar-fixed">
<div class = "navbar">
<div class = "navbar-inner">
<div class = "left"> </div>
<div class = "center">Disabled elements</div>
<div class = "right"> </div>
</div>
</div>
<div class = "page-content">
<div class = "list-block">
<ul>
<li class = "item-content">
<div class = "item-inner">
<div class = "item-title">Item 1</div>
</div>
</li>
<!-- This element will be disabled -->
<li class = "item-content disabled">
<div class = "item-inner">
<div class = "item-title">Item 2 with <i>disabled</i> class applied</div>
</div>
</li>
<li class = "item-content">
<div class = "item-inner">
<div class = "item-title">Item 3</div>
</div>
</li>
<li class = "item-content">
<div class = "item-inner">
<div class = "item-title label">This is input text</div>
<div class = "item-input">
<!-- Disabled input -->
<input type = "text" name = "name" placeholder = "Enter your name">
</div>
</div>
</li>
<!-- Element with disabled input -->
<li class = "item-content">
<div class = "item-inner">
<div class = "item-title label">This is disabled input text</div>
<div class = "item-input">
<!-- Disabled input -->
<input type = "text" name = "name" placeholder = "Enter your name" disabled>
</div>
</div>
</li>
</ul>
</div>
</div>
</div>
</div>
</div>
</div>
<script type = "text/javascript"
src = "https://cdnjs.cloudflare.com/ajax/libs/framework7/1.4.2/js/framework7.min.js"></script>
<script>
var myApp = new Framework7();
</script>
</body>
</html>
输出 (Output)
让我们执行以下步骤，看看上面给出的代码是如何工作的 -
将上面给出的HTML代码保存为服务器根文件夹中的forms_disabled_element.html文件。
以http://localhost/forms_disabled_element.html打开此HTML文件，输出显示如下。
输出显示禁用类和输入元素的形式。
如您所见，不允许用户在输入字段中输入文本，因为输入元素已禁用。
