Bootstrap 表单验证

表单验证
Bootstrap还有三个input元素的验证状态：
- has-success将使标签文本和边框字段的颜色变为绿色
- has-error将使用棕色
- has-warning将使用深红色
下面是一个如何使用验证状态的示例：
<!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">
<div class="form-group has-success">
<label class="control-label"
for="inputField">Input with success</label>
<input type="text" class="form-control" id="inputField"/>
</div>
</body>
</html>这些 has-*类型类只会将颜色应用于form-control， control-label和 help-block类元素。

<label class="col-xs-2 control-label" for="inputSuccess">Username</label>
<div class="col-xs-10">
<input type="text" id="inputSuccess" class="form-control"
placeholder="Input with success">
<span class="help-block">Username is available</span>
</div>
</div>
<div class="form-group has-warning">
<label class="col-xs-2 control-label" for="inputWarning">Password</label>
<div class="col-xs-10">

placeholder="Input with warning">
<span class="help-block">Password strength: Weak</span>
</div>
</div>
<div class="form-group has-error">
<label class="col-xs-2 control-label" for="inputError">Email</label>
<div class="col-xs-10">
<input type="email" id="inputError" class="form-control"
placeholder="Input with error">
<span class="help-block">Please enter a valid email address</span>
</div>
</div>
</form>
</div>
</body>
</html>feedback图标
我们可以通过在.form-group和glyphicon上使用类.has-feedback，以在输入框添加feedback图标。
