bootstrap学习笔记(表单)

1.基础表单：对于基础表单，Bootstrap并未对其做太多的定制性效果设计，仅仅对表单内的fieldset、legend、label标签进行了定制。

fieldset {

min-width: 0;

padding: 0;

margin: 0;

border: 0;

}

legend {

display: block;

width: 100%;

padding: 0;

margin-bottom: 20px;

font-size: 21px;

line-height: inherit;

color: #333;

border: 0;

border-bottom: 1px solid #e5e5e5;

}

label {

display: inline-block;

margin-bottom: 5px;

font-weight: bold;

}

源码

2.水平表单类名“form-horizontal”

.form-horizontal .control-label,

.form-horizontal .radio,

.form-horizontal .checkbox,

.form-horizontal .radio-inline,

.form-horizontal .checkbox-inline {

padding-top: 7px;

margin-top: 0;

margin-bottom: 0;

}

.form-horizontal .radio,

.form-horizontal .checkbox {

min-height: 27px;

}

.form-horizontal .form-group {

margin-right: -15px;

margin-left: -15px;

}

.form-horizontal .form-control-static {

padding-top: 7px;

}

@media (min-width: 768px) {

.form-horizontal .control-label {

text-align: right;

  }

}

.form-horizontal .has-feedback .form-control-feedback {

top: 0;

right: 15px;

}

源码

3.内联表单类名“form-inline”

<form class="form-inline" role="form">

<div class="form-group">

  <label class="sr-only" for="exampleInputEmail2">邮箱</label>

  <input type="email" class="form-control" id="exampleInputEmail2" placeholder="请输入你的邮箱地址">

</div>

<div class="form-group">

  <label class="sr-only" for="exampleInputPassword2">密码</label>

  <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码">

</div>

<div class="checkbox">

<label>

   <input type="checkbox">记住密码

</label>

</div>

<button type="submit" class="btnbtn-default">进入邮箱</button>

</form>

<--  .sr-only:给残障人员用的 -->

<-- .sr-only {

position: absolute;

width: 1px;

height: 1px;

padding: 0;

margin: -1px;

overflow: hidden;

clip: rect(0, 0, 0, 0);

border: 0;

}  -->

示例

表单控件

1.输入框input: 为了让控件在各种表单风格中样式不出错，需要添加类名“form-control”，下面各个表单控件都能加。

<!doctype html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>表单控件——输入框input</title>

    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

</head>

<body>

<form role="form">

  <div class="form-group">

    <input type="email" class="form-control" placeholder="Enter email">

    <input type="text" class="form-control" placeholder="Enter Username">

  </div>

</form>

</body>

</html>

示例

type类型：text button checkbox date datetime datetime-local img file hidden month number password radio range reset search submit tel time url week hidden

2.下拉选择框select：多行选择设置multiple属性的值为multiple

<form>

  <div class="form-group">

      <select multiple class="form-control">  //如果是下拉框就不要加multiple

          <option>踢足球</option>

          <option>游泳</option>

          <option>慢跑</option>

          <option>跳舞</option>

      </select>

  </div>

</form>

示例

3.内联表单类名“form-inline”

<form class="form-inline" role="form">

<div class="form-group">

  <label class="sr-only" for="exampleInputEmail2">邮箱</label>

  <input type="email" class="form-control" id="exampleInputEmail2" placeholder="请输入你的邮箱地址">

</div>

<div class="form-group">

  <label class="sr-only" for="exampleInputPassword2">密码</label>

  <input type="password" class="form-control" id="exampleInputPassword2" placeholder="请输入你的邮箱密码">

</div>

<div class="checkbox">

<label>

   <input type="checkbox">记住密码

</label>

</div>

<button type="submit" class="btnbtn-default">进入邮箱</button>

</form>

<--  .sr-only:给残障人员用的 -->

<-- .sr-only {

position: absolute;

width: 1px;

height: 1px;

padding: 0;

margin: -1px;

overflow: hidden;

clip: rect(0, 0, 0, 0);

border: 0;

}  -->

示例

ea：添加了类名“form-control”类名，则无需设置cols属性。

<form role="form">

  <div class="form-group">

    <textarea class="form-control" rows="3"></textarea>

  </div>

</form>

示例

4.复选框checkbox和单选择按钮radio：水平排列加类名“checkbox-inline”||类名“radio-inline”

<form role="form">

  <div class="form-group">

    <textarea class="form-control" rows="3"></textarea>

  </div>

</form>

示例

4.复选框checkbox和单选择按钮radio：水平排列加类名“checkbox-inline”||类名“radio-inline”

<!doctype html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>表单控件——表单控件大小</title>

    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

</head>

<body>

<form role="form">

  <h3>案例1</h3>

  <div class="checkbox">

    <label>

      <input type="checkbox" value="">

      记住密码

    </label>

  </div>

  <div class="radio">           //如果要水平class=“radio-inline”

    <label>

      <input type="radio" name="optionsRadios" id="optionsRadios1" value="love" checked>

      喜欢

    </label>

  </div>

    <div class="radio">         //如果要水平class=“radio-inline”

    <label>

      <input type="radio" name="optionsRadios" id="optionsRadios2" value="hate">

      不喜欢

    </label>

  </div>

</form>

</body>

</html>

display: block;

min-height: 20px;

padding-left: 20px;

margin-top: 10px;

margin-bottom: 10px;

}

.radio label,

display: inline;

font-weight: normal;

.radio input[type="radio"],

.radio-inline input[type="radio"],

.checkbox input[type="checkbox"],

.checkbox-inline input[type="checkbox"] {

float: left;

margin-left: -20px;

}

.radio + .radio,

.checkbox + .checkbox {

margin-top: -5px;

}

源码

.radio-inline,

.checkbox-inline {

display: inline-block;

padding-left: 20px;

margin-bottom: 0;

font-weight: normal;

vertical-align: middle;

cursor: pointer;

}

.radio-inline + .radio-inline,

.checkbox-inline + .checkbox-inline {

margin-top: 0;

margin-left: 10px;

}

水平排列源码

5.控件大小：类名input-sm:让控件比正常大小更小；类名input-lg:让控件比正常大小更大；宽度配合Bootstrap的网格系统

.input-sm {

height: 30px;

padding: 5px 10px;

font-size: 12px;

line-height: 1.5;

border-radius: 3px;

}

select.input-sm {

height: 30px;

line-height: 30px;

}

textarea.input-sm,

select[multiple].input-sm {

height: auto;

}

.input-lg {

height: 46px;

padding: 10px 16px;

font-size: 18px;

line-height: 1.33;

border-radius: 6px;

}

select.input-lg {

height: 46px;

line-height: 46px;

}

textarea.input-lg,

select[multiple].input-lg {

height: auto;

}

源码

6.表单控件状态（焦点状态）：类名form-control

.form-control:focus {

border-color: #66afe9;

outline: 0;

  -webkit-box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);

box-shadow: inset 0 1px 1pxrgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6);

}

源码

7.表单控件状态(禁用状态)：form-control别忘记加①在需要禁用的表单控件上加上“disabled”；②fieldset设置了disabled属性，整个域都将处于被禁用状态。

.form-control[disabled],

.form-control[readonly],

fieldset[disabled] .form-control {

cursor: not-allowed;

background-color: #eee;

opacity: 1;

}

源码

8.表单控件状态(验证状态):1、.has-warning:警告状态（黄色） 2、.has-error：错误状态（红色） 3、.has-success：成功状态（绿色）

：需要类名has-feedback + <span class="glyphicon glyphicon-remove form-control-feedback"></span>

9.表单提示信息："help-block" bootstrap学习笔记(表单)

.help-block {

display: block;

margin-top: 5px;

margin-bottom: 10px;

color: #737373;
