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>

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>     
View Code

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)

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>表单控件大小</title>
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">
</head>
<body>
<h1>案例1</h1>
<form role="form">
  <div class="form-group">
    <label class="control-label">控件变大</label>
    <input class="form-control input-lg" type="text" placeholder="添加.input-lg,控件变大">
  </div>
  <div class="form-group">
    <label class="control-label">正常大小</label>
    <input class="form-control" type="text" placeholder="正常大小">
  </div>  
  <div class="form-group">
    <label class="control-label">控件变小</label>
    <input class="form-control input-sm" type="text" placeholder="添加.input-sm,控件变小">

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)

 

<h3>示例1</h3>
<form role="form" class="form-horizontal">
  <div class="form-group">
    <div class="col-xs-6">
      <input class="form-control input-lg" type="text" placeholder="不是焦点状态下效果">
    </div>
    <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>   
<form role="form">
  <fieldset disabled>
    <div class="form-group">
      <label for="disabledTextInput">禁用的输入框</label>
      <input type="text" id="disabledTextInput" class="form-control" placeholder="禁止输入">
    </div>
    <div class="form-group">
      <label for="disabledSelect">禁用的下拉框</label>
      <select id="disabledSelect" class="form-control">
        <option>不可选择</option>
      </select>
    </div>
    <div class="checkbox">
      <label>
        <input type="checkbox"> 无法选择
      </label>
    </div>
    <button type="submit" class="btn btn-primary">提交</button>
  </fieldset>
</form> 
<br>
<form role="form">
  <fieldset disabled>
    <legend><input type="text" class="form-control" placeholder="显然我颜色变灰了,但是我没被禁用,不信?单击试一下" /></legend>
    <div class="form-group">
      <label for="disabledTextInput">禁用的输入框</label>
      <input type="text" id="disabledTextInput" class="form-control" placeholder="禁止输入">
    </div>
    <div class="form-group">
      <label for="disabledSelect">禁用的下拉框</label>
      <select id="disabledSelect" class="form-control">
        <option>不可选择</option>
      </select>
    </div>
    <div class="checkbox">
      <label>
        <input type="checkbox"> 无法选择
      </label>
