表单

表单元素是允许用户在表单中（比如：文本域、下拉列表、单选框、复选框等等）输入信息的元素
文本：

<form>
username:<input type = "text" name = "username" />
<br />
password:<input type = "password" name = "password" />
<br />
<textarea cols="11" rows="10"></textarea>
</form>

单选

<form>
<input type = "radio" name = "sex" value = "男" />男
<br />
<input type = "radio" name = "sex" vulue = "女" />女
<br />
</form>

多选

<form>
<input type = "checkbox" name = "111" />1 <br />
<input type = "checkbox" name = "222" />2 <br />
<input type = "checkbox" name = "333" />3 <br />
<input type = "checkbox" name = "444" />4 <br />
</form>

下拉列表

disabled = "disabled" 禁用该下拉列表
size = "2" 下拉列表可见选项的数目

<form>
<select name = "list" disbaled = "disabled"size = "4">
<option>list1</option>
<option>list2</option>
<option>list3</option>
</form>

当用户单击确认按钮时，表单的内容会被传送到另一个文件。表单的动作属性定义了目的文件的文件名。

<form action = "html.do" method = "get">
username:<input tyep = "text" name = "username" />
<input type = "submit" value = "提 交" />
</form>
