This time I will show you how to use the internal form tags of html. What are the precautions when using the internal tags of html form. The following is a practical case, let's take a look.

<html> 
<head> 
<title> form表单的使用 </title> 
<!-- 
标签名称:form 表单标签 
属性:action:提交的去向,目标地址的url 
method:设置提交请求的方式,get和post;默认为get 
get和post提交有什么区别?------------------------ 
get传输:将内容信息放在地址栏传输,而且长度限制在1k,而且安全性不好。 
post传输:将内容房子body信息中传输。没有长度限制。 
子标签: 
input标签:需要提交其中的value,必须有一个name属性。 
属性:type:password 等 
//------------ 
通过下面的实例的演示,发现在某些情况下可以用form去做链接,而且做链接的同时还能提交数据到 
这个目标的地址文件上。 
fieldset标签:定义域 
legend标签:定义域的标题 
--> 
</head> 
<body> 
<fieldset> 
<legend>form表单标签,子标签实例:</legend> 
<form action="01列表.html" method="get"> 
<table border="1px" width="800px"> 
<tr>

List tag:

<select name="cars"> 
<option value="volvo">Volvo</option> 
<option value="saab">Saab</option> 
<option value="fiat" selected="selected">Fiat</option> 
<option value="audi">Audi</option> 
</select>
</tr> 
<tr>

CheckboxExample:

I like bikes:

<input type="checkbox" name="Bike">

I like cars:

<input type="checkbox" name="Car">
</tr> 
<tr>

Radio button:
Male:

<input type="radio" checked="checked" name="Sex" value="male">

Female:

<input type="radio" name="Sex" value="female"> 
</form> 
<p>当用户点击一个单选按钮时,该按钮会变为选中状态,其他所有按钮会变为非选中状态。</p> 
</tr> 
<tr>

Text field:

<textarea rows="10" cols="30">文本域标签的使用</textarea> 
</tr> 
<tr> 
</tr> 
<tr> 
</tr> 
<tr> 
<td>账号:</td> 
<td> 
<input name="userid"> 
</td> 
</tr> 
<tr> 
<td>密码:</td> 
<td> 
<input name="pwd"> 
</td> 
</tr> 
<tr> 
<td> 
<input type="submit" value="确认提交"/> 
</td> 
<td> 
<input type="reset" value="重置"/> 
</td> 
</tr> 
</table> 
</form> 
</fieldset> 
</body> 
</html>
