当使用ckeditor控件时，需要校验输入内容是否为空的一种解决办法（转帖）

<script language = "javascript">
<!--
function checkForm(){
if (document.form1.content.value==""){
alert("请输入内容！");
return false;
}
return true;
}
//-->
</script>
<form name="form1" method="post" action="" onsubmit="return checkForm();">
<FCK:editor id="content" basePath="fckeditor/" height="350" >
</FCK:editor>
<input type="submit" name="Submit" value="发布">
</form>

<script language = "javascript">
<!--
function checkForm(){
setTimeout("SendForm()",50);
return false;
}
function SendForm(){
if (document.form1.content.value==""){
alert("请输入内容！");
return;
}
document.form1.submit();
}
//-->
</script>
<form name="form1" method="post" action="" onsubmit="return checkForm();">
<FCK:editor id="content" basePath="fckeditor/" height="350" >
</FCK:editor>
<input type="submit" name="Submit" value="发布">
</form>
