为什么里面的javascript没执行呢?貌似没执行CheckPost()判断啊?
 include("conn.php") ;
 include('head.php') ;
 if($_POST['submit'])
 {
  $sql="insert into message(id,user,title,content,lastdate) values('','$_POST[user]','$_POST[title]','$_POST[content]',now())";
  mysql_query("$sql") ;
  echo "发表成功!" ;
}

?>

 



  用户:

  标题:

  内容:





------解决方案--------------------
alert(“请填写用户”); 全角符号导致了浏览器解析错误吧
------解决方案--------------------
myform.user.value=="" js获取对象值有这种语法吗?

都改成这样 document.getElementByName("user").value;
------解决方案--------------------
function CheckPost(myform)
{
if (myform.user.value=="")
{
alert(“请填写用户”);
myform.user.focus();
return false;
}
if (myform.title.value.length{
alert("标题不能少于5个字符");
myform.title.focus();
return false ;
}
}




js参数都没传, "myform"哪来的啊
------解决方案--------------------
