学习使用bootstarp基本控件（table、form、button）

bootstrap为我们定义了简洁易用的样式，我们只需要很少的样式指定，就可以完成简约优雅的页面展示。
本篇主要介绍以下几个基本控件：
1. table
2. form
3. button
1. 表格（table）依旧使用<table><thead><tbody><tr><th><td>来表现表格。有如下的类来控制table的属性， table样式默认会占满父容器

 <div class="container"><div class="row"><div class="col-md-8 col-md-offset-2"><table class="table table-bordered table-striped table-hover"><tr><th>标题一</th><th>标题二</th><th>标题三</th></tr><tr><td>1</td><td>2</td><td>3</td></tr><tr><td>4</td><td>5</td><td>6</td></tr></table></div></div></div>

将任何.table包裹在.table-responsive中即可创建响应式表格，其会在小屏幕设备上（小于768px）水平滚动。当屏幕大768px宽度时，水平滚动条消失。
2. 表单form, 有如个几种样式定义

lable与控件要用form-group类型的div包起来，默认表单如下

 <div class="container"><form><div class="form-group"><label for="exampleInputEmail1">Email address</label><input type="email" class="form-control" id="exampleInputEmail1"placeholder="Enter email"></div><div class="form-group"><label for="exampleInputPassword1">Password</label><input type="password" class="form-control"id="exampleInputPassword1" placeholder="Password"></div><div class="checkbox"><label> <input type="checkbox"> Check me out</label></div><button type="submit" class="btn btn-default">Submit</button></form></div>

内联表单，为label指定sr-only类别，可隐藏掉标签，但必须不可省略lable.

<div class="container"><form class="form-inline"><div class="form-group"><label for="exampleInputEmail1" class="sr-only">Email address</label><input type="email" class="form-control" id="exampleInputEmail1"placeholder="Enter email"></div><div class="form-group"><label for="exampleInputPassword1">Password</label><input type="password" class="form-control"id="exampleInputPassword1" placeholder="Password"></div><div class="checkbox"><label> <input type="checkbox"> Check me out</label></div><button type="submit" class="btn btn-default">Submit</button></form></div>

水平类型的表单，要为lable与标签组指定长度，采用栅格系统的布局方式。 label右对齐，标签组左对齐。

 <div class="container"><form class="form-horizontal"><div class="form-group"><label for="exampleInputEmail1" class="col-md-2 control-label">Emailaddress</label><div class="col-md-8"><input type="email" class="form-control" id="exampleInputEmail1"placeholder="Enter email"></div></div><div class="form-group" ><label for="exampleInputPassword1" class="col-md-2 control-label">Password</label><div class="col-md-8"><input type="password" class="form-control"id="exampleInputPassword1" placeholder="Password"></div></div><div class="checkbox col-md-offset-2"><label> <input type="checkbox"> Check me out</label></div><button type="submit" class="btn btn-default col-md-offset-2">Submit</button></form></div>

form表单验证，bootstrap3支持表单的自定义验证。加入req uired表示表单必填，node.setCustomValidity可以设置表单的自定义验证

<div class="container"><form class="form-horizontal"><div class="form-group"><label for="exampleInputEmail1" class="col-md-2 control-label">Emailaddress</label><div class="col-md-8"><input type="email" class="form-control" id="exampleInputEmail1"placeholder="Enter email" required></div></div><div class="form-group"><label for="password1" class="col-md-2 control-label">Password</label><div class="col-md-8"><input type="password" class="form-control"id="password1" placeholder="Password" required onchange="checkPassword（）"></div></div><div class="form-group"><label for="password2" class="col-md-2 control-label" onchange="checkPassword（）"> Password2</label><div class="col-md-8"><input type="password" class="form-control"id="password2" placeholder="Password2" required></div></div><div class="checkbox col-md-offset-2"><label> <input type="checkbox"> Check me out</label></div><button type="submit" class="btn btn-default col-md-offset-2">Submit</button></form></div><script>function checkPassword（） {var pwd1 = $（"#password1"）.val（）;var pwd2 = $（"#password2"）.val（）;if （pwd1 ！= pwd2） {document.getElementById（"password1"）.setCustomValidity（"两次输入的密码不一致"）;} else {document.getElementById（"password1"）.setCustomValidity（""）;}}</script>

3. button的样式

使用.btn-lg、.btn-sm、.btn-xs可以获得不同尺寸的按钮，给按钮添加.btn-block可以使其充满父节点100%的宽度，而且按钮也变为了块级（block）元素， <a>、<button>或<input>元素添加按钮class。

<div class="container"><button type="button" class="btn btn-default btn-block">Default</button><button type="button" class="btn btn-primary btn-block">Primary</button><button type="button" class="btn btn-success">Success</button><button type="button" class="btn btn-info">Info</button><button type="button" class="btn btn-warning">Warning</button><button type="button" class="btn btn-danger">Danger</button><button type="button" class="btn btn-link">链接</button><a class="btn btn-default" href="#" role="button">Link</a><button class="btn btn-default" type="submit">Button</button><input class="btn btn-default" type="button" value="Input"><input class="btn btn-default" type="submit" value="Submit"></div>
