本文主要讲解的是表单,这个其实对于做过网站的人来说,并不陌生,而且可以说是最为常用的提交数据的Form表单。本文主要来讲解一下内容:
1.基本案例
2.内联表单
3.水平排列的表单
4.被支持的控件
5.静态控件
6.控件状态
7.控件尺寸
8.帮助文本
基本案例
单独的表单控件会被自动赋予一些全局样式。所有设置了.form-control的<input>、<textarea>和<select>元素都将被默认设置为width: 100%;。将label和前面提到的这些控件包裹在.form-group中可以获得最好的排列。
form
role
=
"form"
>
<
div
class
=
"form-group"
>
<
label
for
=
"exampleInputEmail1"
>Email address</
label
>
<
input
type
=
"email"
class
=
"form-control"
id
=
"exampleInputEmail1"
placeholder
=
"Enter email"
>
</
div

<

</

内联表单
为左对齐和inline-block级别的控件设置.form-inline,可以将其排布的更紧凑。
需要设置宽度:在Bootstrap中,input、select和textarea默认被设置为100%宽度。为了使用内联表单,你需要专门为使用到的表单控件设置宽度。
一定要设置label:如果你没有为每个输入控件设置label,屏幕阅读器将无法正确识读。对于这些内联表单,你可以通过为label设置.sr-only已将其隐藏。

"form-inline"

Inline checkboxes
通过将.checkbox-inline 或 .radio-inline应用到一系列的checkbox或radio控件上,可以使这些控件排列在一行。
<

"checkbox-inline"

input
type
=
"checkbox"
id
=
"inlineCheckbox1"
value
=
"option1"

被禁用的fieldset
为<fieldset>设置disabled属性可以禁用<fieldset>中包含的所有控件。<a>标签的链接功能不受影响
这个class只改变<a class="btn btn-default">按钮的外观,并不能禁用其功能。建议自己通过JavaScript代码禁用链接功能。
跨浏览器兼容性
虽然Bootstrap会将这些样式应用到所有浏览器上,Internet Explorer 9及以下浏览器中的<fieldset>并不支持disabled属性。因此建议在这些浏览器上通过JavaScript代码来禁用fieldset
<
form
role
=
"form"
>
<
fieldset
disabled>
<
div
class
=
"form-group"
>
<
label
for
=
"disabledTextInput"
>Disabled input</

>
<

type
=
"text"
id

调整列尺寸
用栅格系统中的列包裹input或其任何父元素,都可很容易的为其设置宽度。
<
div
class
=
"row"
>
<
div
class
=
"col-xs-2"
>
<
input
type
=
"text"
class
=
"form-control"
placeholder
=
".col-xs-2"
>
</
div
>
<
div
class
=
"col-xs-3"
>
<
input
type
=
"text"
class
=
"form-control"
placeholder
=
".col-xs-3"
>
</
div
>
<
div
class
=
"col-xs-4"
>
<
input
type
=
"text"
class
=
"form-control"
placeholder
=
".col-xs-4"
>
</
