关于FCKeditor内容是否为空？

[Eclipse_80]

FCKeditor已经添加了图片，但是还是报内容不得为空！
js方法如下：

function commitForm(){

	if(/^\s*$/.test((FCKeditorAPI.GetInstance("news.ncontent").EditorDocument.body.innerText))){
    	alert("内容不得为空");
    	return false;
    }
｝

调用FCKeditor实体：

<!-- fckeditor -->
<script type="text/javascript" src="<%=basePath %>fckeditor/fckeditor.js"></script>
<script type="text/javascript">

window.onload = function()
{
	// Automatically calculates the editor base path based on the _samples directory.
	// This is usefull only for these samples. A real application should use something like this:
	// oFCKeditor.BasePath = '/fckeditor/' ;	// '/fckeditor/' is the default value.
	var sBasePath = "<%=request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath()+"/fckeditor/"%>"
	var oFCKeditor = new FCKeditor( 'news.ncontent' ) ;
	oFCKeditor.BasePath	= sBasePath ;
	oFCKeditor.ReplaceTextarea() ;
}
</script>
<!-- end of fvkeditor -->

其中内容（news.ncontent ）是一个textarea被FCKeditor替换，提交的时候调用commitForm()方法！
麻烦高人帮忙看下！谢谢
