为什么验证账户的PHP放入,使用AJAX. 放在表单中可以实现,但是放在一个HTML中就失效了.
时间：2010-09-28
来源：互联网
首先以下是ajax1.html 如果将以下
if($_POST['submit']=='注册')
{
?>以后的内容改成
<HTML><HEAD><TITLE>新用户注册</TITLE><HEAD>
<BODY><DIV><FORM METHOD='post' action="x2.php">
<CENTER>
<B>新用户注册,点击此处
<A href=javacript:history.go(-1);>返回</A>
</B><P>
用户名:
<input type=text name="newname" size=16><BR>
密码:
<input type=password name="newpwd" size=16><BR>
密码确认:
<input type=password name="tbxRePwd" size=16><BR>
提问:
<input type=text name="FPWD" size=16><BR>
回答:
<input type=text name="FPAW" size=16><BR>
邮箱:
<input type=text name="email" size=16><BR>
<input type=submit name="submit" value="确认">
<input type=reset name="reset" value="清除"><BR>
</CENTER>
</form></div></body></html>
则可以实现用户验证.但是改成下面的形式就无法实现验证/
如果点击"同意以下服务条款，提交注册信息"这个按钮,将会跳转到空白页无法进行验证.

.困惑了我1个月了..看了PHP100的视频到现在55章还没找到可以解决的方案.希望某个大侠帮帮忙..
======
还要个问题.用AJAX+PHP+JQuery 如何将我上面输写的ajax1.php,ajax2.php,ajax21.php,ajax22.php,ajax23.php,ajax24.php整合成一个.
if($_POST['submit']=='注册')
{
?>以后的内容改成
<HTML><HEAD><TITLE>新用户注册</TITLE><HEAD>
<BODY><DIV><FORM METHOD='post' action="x2.php">
<CENTER>
<B>新用户注册,点击此处
<A href=javacript:history.go(-1);>返回</A>
</B><P>
用户名:
<input type=text name="newname" size=16><BR>
密码:
<input type=password name="newpwd" size=16><BR>
密码确认:
<input type=password name="tbxRePwd" size=16><BR>
提问:
<input type=text name="FPWD" size=16><BR>
回答:
<input type=text name="FPAW" size=16><BR>
邮箱:
<input type=text name="email" size=16><BR>
<input type=submit name="submit" value="确认">
<input type=reset name="reset" value="清除"><BR>
</CENTER>
</form></div></body></html>
则可以实现用户验证.但是改成下面的形式就无法实现验证/
如果点击"同意以下服务条款，提交注册信息"这个按钮,将会跳转到空白页无法进行验证.
