Bootstrap中的表单控件状态主要有三种：焦点状态，禁用状态，验证状态。

 
一、焦点状态：该状态告诉用户可输入或选择东西
焦点状态通过伪类“:focus”以实现。
<span style="font-size: 15px;">bootstrap.css相应源码：</span>
<span style="color: #800000;">.form-control:focus </span>{<span style="color: #ff0000;">
    border-color</span>:<span style="color: #0000ff;"> #66afe9</span>;<span style="color: #ff0000;">
    outline</span>:<span style="color: #0000ff;"> 0</span>;<span style="color: #ff0000;">   //删除了outline的默认样式
    -webkit-box-shadow</span>:<span style="color: #0000ff;"> inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6)</span>;<span style="color: #ff0000;">  //添加了阴影效果
    box-shadow</span>:<span style="color: #0000ff;"> inset 0 1px 1px rgba(0,0,0,.075), 0 0 8px rgba(102, 175, 233, .6)</span>;

使用方法：给控件添加类名“form-control”。
<span style="font-size: 15px;">eg:</span>
<span style="color: #0000ff;"><span style="color: #800000;">input </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="form-control"</span><span style="color: #ff0000;"> type</span><span style="color: #0000ff;">="text"</span><span style="color: #ff0000;"> placeholder</span><span style="color: #0000ff;">="不是焦点状态下效果"</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">input </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="form-control"</span><span style="color: #ff0000;"> type</span><span style="color: #0000ff;">="text"</span><span style="color: #ff0000;"> placeholder</span><span style="color: #0000ff;">="焦点状态下效果"</span><span style="color: #0000ff;">></span></span></span>

效果图如下所示：（焦点状态下为蓝色边框效果）
焦点状态下，file、radio、checkbox控件的效果与普通的input空间不完全一样，因为bootstrap对它们做了特殊处理。
<span style="font-size: 15px;">bootstrap.css相应源码：</span>
<span style="color: #800000;">input[type="file"]:focus,
input[type="radio"]:focus,
input[type="checkbox"]:focus </span>{<span style="color: #ff0000;">
outline</span>:<span style="color: #0000ff;"> thin dotted</span>;<span style="color: #ff0000;">
outline</span>:<span style="color: #0000ff;"> 5px auto -webkit-focus-ring-color</span>;<span style="color: #ff0000;">
outline-offset</span>:<span style="color: #0000ff;"> -2px</span>;

<span style="font-size: 15px;"><strong>二、禁用状态：</strong>该状态告诉用户不可以输入或选择东西</span>
Copy after login




<span style="font-size: 15px;">禁用状态是通过在表单控件上添加"disabled"属性以实现。</span>

<span style="font-size: 15px;">bootstrap.css相应源码：</span>
Copy after login




<span style="color: #800000;">.form-control[disabled],
.form-control[readonly],
fieldset[disabled] .form-control </span>{<span style="color: #ff0000;">
    cursor</span>:<span style="color: #0000ff;"> not-allowed</span>;<span style="color: #ff0000;">
    background-color</span>:<span style="color: #0000ff;"> #eee</span>;<span style="color: #ff0000;">
    opacity</span>:<span style="color: #0000ff;"> 1</span>;
}
Copy after login




<span style="font-size: 15px;">使用方法：在需要禁用的表单控件上加上"diabled"属性即可。</span>

<span style="font-size: 15px;">效果图如下所示：</span>

<span style="font-size: 15px;">说明：禁用状态下控件背景色为灰色，且手型变为不准输入的形状，若表单控件不使用类名"form-control"，则禁用的控件只有一个不准输入的手型。</span>

<span style="font-size: 15px;">PS：在Bootstrap中，若fieldset设置了"disabled"属性，则整个域都处于被禁用状态。</span>

<span style="font-size: 15px;"><strong>三、验证状态：</strong>该状态告诉用户，他们的操作是否正确</span>
Copy after login

在Bootstrap中提供3种验证状态样式：



① .has-success : 成功状态（绿色）


② .has-error : 错误状态（红色）


③ .has-warning : 警告状态（黄色）


使用方法：在form-group容器上添加对应的状态类名即可。

<span style="font-size: 15px;">在Bootstrap的表单验证中，不同状态会提供不同的icon,如成功是个对号"√",错误是个叉号"×"等。</span>

<span style="font-size: 15px;">若想让表单在不同状态下显示对应的icon,则只需在对应状态下添加类名"has-feedback"。</span>

<span style="font-size: 15px;">PS:类名"has-feedback"要与"has-error"、"has-warning"、"has-success"配合使用。</span>
