注册/登陆页面HTML代码该怎么写?

以下为个人原创教学例子,任何人引用需注明出自百度知道用户am7972,楼主可供参考

该例子涵盖了文本框、密码框、下拉菜单、单选框、复选框及文本区的使用

同时在数据的使用方面涵盖了文本型、数值型、日期型、布尔型的使用

也涵盖了在会员信息入数据库前,进行严格的数据检查

不足处,JS验证还不是太完善,不过有服务端认证足够了

}

if(document.userinfo.username.value.length > 10)

html性别按钮如何写

input标签type写成radio单选。后面的文字自己添加,男女两个的input都要用相同的name值,因为只能选择一个。

<form action=”/example/html/form_action.asp” method=”get”>

  <input type=”radio” name=”sex” value=”male” /> Male<br />

  <input type=”radio” name=”sex” value=”female” /> Female<br />

  <input type=”submit” value=”Submit” />

</form>

html中性别下拉框怎么写

<select>

<option value=”男”>男</option>

<option value=”女”>女</option>

</select>

样式自己加哦~

网页的登录界面和注册页面一般是怎么编写用html

一般登录界面用html写

因为登录界面没有太多的花哨

一般很简单

只是一个框架

表单提交用

跳到一个jsp页面去处理

如果正确就跳转到你想要到的界面

jsp可以通过

会话

或cookie或上下文、url等把页面联系起来

数据库

一般用mysql

注册判断的地方用js联系数据库就可以了

很简单的
