表单
bootstrap为表单提供三种样式:默认表单,水平表单,内联表单。
<form class="form-horizontal" role="form">
<!--默认表单-->
</form>
<!--分割线-->
<form class="form-horizontal" role="form">
<!--水平表单-->
</form>
<!--分割线-->
<form class="form-inline" role="form">
<!--内联表单-->
</form>
水平表单效果图(ps:bootstrap默认表单是label标签和表单元素上下排列)
内联表单效果图(ps:内联表单就是把垂直排列的表单元素水平排列)
<form role="form">
<div class="form-group">
<label for="exampleInputEmail1">邮箱:</label>
<input type="email" class="form-control" id="exampleInputEmail1" placeholder="请输入您的邮箱地址">
</div>
<div class="form-group">
<label for="exampleInputPassword1">密码</label>
<input type="password" class="form-control" id="exampleInputPassword1" placeholder="请输入您的邮箱密码">
</div>
<div class="checkbox">
<label>
<input type="checkbox"> 记住密码
</label>
</div>
<button type="submit" class="btn btn-default">进入邮箱</button>
</form>
表单元素
下拉框<select></select>
bootstrap除了传统的单选下拉框外,还新增了多选下拉框。
<form role="form">
<!--单选下拉框-->
<div class="form-group">
<select class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
</select>
</div>
<!--多选下拉框-->
<div class="form-group">
<select multiple class="form-control">
<option>1</option>
<option>2</option>
<option>3</option>
<option>4</option>
<option>5</option>
<option>6</option>
<option>7</option>
</select>
</div>
</form>

单选,复选框
bootstrap对checkbox和radio做了一些优化。用<div></div>包裹一组checkbox或者radio元素。用class="checkbox"或者class="radio"赋值div样式。
<form role="form">
<h2>选择框<small>案例</small></h2>
<!--复选框-->
<div class="checkbox">
<label>
<input type="checkbox" value="">
复选
</label>
</div>
<!--单选框-->
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios1" value="love" checked>
单选1
</label>
</div>
<div class="radio">
<label>
<input type="radio" name="optionsRadios" id="optionsRadios2" value="hate">
单选2
</label>
</div>
</form>
优化后的checkbox选择框和文本对齐更完美。
水平选择框
一组checkbox或radio呈横向水平排列
class="checkbox-inline"
<form role="form">
<div class="form-group">
<label class="checkbox-inline">
<input type="checkbox" value="option1">游戏
</label>
<label class="checkbox-inline">
<input type="checkbox" value="option2">摄影
</label>
<label class="checkbox-inline">
<input type="checkbox" value="option3">旅游
</label>
</div>
<div class="form-group">
<label class="radio-inline">
<input type="radio" value="option1" name="sex">男性
</label>
<label class="radio-inline">
<input type="radio" value="option2" name="sex">女性
</label>
<label class="radio-inline">
<input type="radio" value="option3" name="sex">保密
</label>
</div>
</form>
按钮
bootstrap的按钮更漂亮直接看看效果吧
class="btn",基本按钮样式。
class="btn btn-info(primary,success,warning,danger)",带颜色的按钮样式。
<button class="btn btn-primary">按钮</button>
<a class="btn btn-info">超链接</a>
<input type="submit" class="btn btn-success"/>
<input type="text" value="输入框" class="btn btn-danger"/>

调整表单元素尺寸
元素尺寸调节:
class="input input-lg" (大号)
class="input" (普通)
class="input input-sm" (小号)
(ps:input也可以替换其他元素,如:btn,text)

表单控件禁用
bootstrap禁用表单控件仅仅需要一个属性:disabled(任何表单元素都有disabled属性)

<div class="col-xs-6">
<input class="form-control input-lg" id="disabledInput" type="text" placeholder="表单已被禁用,不可输入" disabled>
</div>
</div>
</form>
<br>
<h3>示例2</h3>
