表單驗證
Bootstrap還有三個input元素的驗證狀態(tài)：
- has-success將使標簽文本和邊框字段的顏色變?yōu)榫G色
- has-error將使用棕色
- has-warning將使用深紅色
下面是一個如何使用驗證狀態(tài)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>這些 has-*類型類只會將顏色應用于form-control， control-label和 help-block類元素。

<span class="help-block">Username is available</span>
</div>
</div>
<div class="form-group has-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圖標
我們可以通過在.form-group和glyphicon上使用類.has-feedback，以在輸入框添加feedback圖標。
