dedecms 文章发布时：
1、判断标题采用的是判断表单值
if(document.form1.title.value==""){
alert("<?php echo $cInfos['titlename']; ?>不能为空！");
document.form1.title.focus();
return false;
}2、但是内容是这个形式
<?php GetEditor("body","",350,"Member"); ?>
如何在会员提交时，判断内容不能小于200字，然后弹出提示窗口。谢谢！

上面的代码忽略了这一点。
客户端端可以采用js的字符串处理函数
服务端可以采用php的字符串长度处理函数。
具体的要自己查了。
<script type="text/javascript">var txt="Hello World!"
document.write(txt.length)</script>
<?php
echo strlen(obj);
?>
if(mb_strlen($str,'utf-8')>300){
echo "<script>alert('内容过长')</script>";
exit();
}
