PHP利用Ajax连接到数据库
直接亮出来代码好了 这个是一个添加文章类别功能的页面
sortadd.php

<script><br />function checksort(){<br /> var txt_sort=form1.txt_sort.value;<br /> if(txt_sort==""){<br /> window.alert("请填写文章类别!");<br /> form1.txt_sort.focus();<br /> return false;<br /> }else{<br /> createRequest('checksort.php?txt_sort='+txt_sort);<br /> }<br />}<br /></script>



 
 
 
 
 
 
 
 

 

 
 

 

 






然后是checksort.php
/*
添加分类信息处理页checksort.php
 */
  $link=mysql_connect("localhost","root","8346322");
  mysql_select_db("wp",$link);
  $GB2312string=iconv('UTF-8','gb2312//IGNORE',$RequestAjaxString);
  mysql_query("set names gb2312");
  $sort=$_GET[txt_sort];
  mysql_query("insert into wp_jargon(jargon_text) values('$sort')");
  // header('Content-type:text/html;charset=GB2312');
?>


运行结果是:
如果添加的框是空的,还可以正常跳出提示对话框;但是如果不为空的时候就出错,几乎没什么相应。求求高手来解决下
