纯js集成fck 以及 判断fck内容是否为空的js代码

<script type="text/javascript">
<!--
// 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 ='/fckeditor/';

var oFCKeditor = new FCKeditor( 'news_content' ) ;
oFCKeditor.BasePath    = sBasePath ;
oFCKeditor.Height    = 400 ;
oFCKeditor.Width    = 600 ;
oFCKeditor.Value    = '' ;
oFCKeditor.Create() ;
//-->

//取fck内容的长度
function GetMessageLength(str)
{
    var oEditor = FCKeditorAPI.GetInstance(str) ;
    var oDOM = oEditor.EditorDocument ;
    var iLength ;

    if ( document.all )        // If Internet Explorer.
    {
        iLength = oDOM.body.innerText.length ;
    }
    else                    // If Gecko.
    {
        var r = oDOM.createRange() ;
        r.selectNodeContents( oDOM.body ) ;
        iLength = r.toString().length ;
    }
//    oEditor.InsertHtml('')
return iLength
}  

function CheckPost(){
    if(GetMessageLength("news_content")=='0')
    {
        alert('请输入内容');       
        return false;
    }
}

//取fck内容
function GetMessageContent(str)
{
     var oEditor = FCKeditorAPI.GetInstance(str) ;
     return oEditor.GetXHTML();

当有以下config.php配置时

$Config['UserFilesPath'] = '/upload/' ;

$Config['AllowedExtensions']['Image']    = array('bmp','gif','jpeg','jpg','png') ;
$Config['DeniedExtensions']['Image']    = array() ;
$Config['FileTypesPath']['Image']        = $Config['UserFilesPath'] . 'image/' ;
$Config['FileTypesAbsolutePath']['Image']= ($Config['UserFilesAbsolutePath'] == '') ? '' : $Config['UserFilesAbsolutePath'].'image/' ;
$Config['QuickUploadPath']['Image']        = $Config['UserFilesPath'] ;
$Config['QuickUploadAbsolutePath']['Image']= $Config['UserFilesAbsolutePath'] ;

上传时，
快速上传将直接上传到upload目录下
非快速上传将传到upload/image目录下

浏览服务器时
图片浏览将指向upload/image

所以快速上传的图片在浏览服务器时，不能浏览到。
