Bootstrap 表单禁用和只读
2017-01-05 16:29:08 更新
禁用表单控件
如果已使用disabled属性禁用input元素，则Bootstrap具有为其定义的样式。例如，以下这段代码：
<!DOCTYPE html>
<html lang="en">
<head>
<script type="text/javascript"
src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
<link rel="stylesheet"
href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">
<link rel="stylesheet"
href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap-theme.min.css">
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script
src="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/js/bootstrap.min.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$(".myDropdownHandle").dropdown("toggle");
});
</script>
</head>
<body style="margin:30px">
<input class="form-control"
type="text"
placeholder="Disabled input here..." disabled>
</body>
</html>禁用字段集
不是单独禁用表单控件，我们可以通过向<fieldset>元素中添加disabled属性来禁用字段集中的所有表单控件。
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap-theme.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>
<style type="text/css">
.bs-example{
margin: 20px;
}
</style>
</head>
<body>
<div class="bs-example">
<form class="form-horizontal">
<fieldset disabled="disabled">
<div class="form-group">
<label for="inputEmail" class="control-label col-xs-2">Email</label>
<div class="col-xs-10">
<input type="email" class="form-control" id="inputEmail" placeholder="Email">
</div>
</div>
<div class="form-group">
<label for="inputPassword" class="control-label col-xs-2">Password</label>
<div class="col-xs-10">
<input type="password" class="form-control" id="inputPassword" placeholder="Password">
</div>
</div>
<div class="form-group">
<div class="col-xs-offset-2 col-xs-10">
<div class="checkbox">
<label><input type="checkbox"> Remember me</label>
</div>
</div>
</div>
<div class="form-group">
<div class="col-xs-offset-2 col-xs-10">
<button type="submit" class="btn btn-primary">Login</button>
</div>
</div>
</fieldset>
</form>
</div>
</body>
</html>只读
在input元素上添加只读属性，以创建防止用户输入的只读输入控件。
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap-theme.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script>
<style type="text/css">
.bs-example{
margin: 20px;
}
</style>
</head>
<body>
<div class="bs-example">
<form>
<input type="text" class="form-control" placeholder="Readonly input" readonly="readonly">
</form>
</div>
</body>
</html>
