JS integration fckeditor and method to determine whether the content is empty

This article describes the JS integration fckeditor and the method of judging whether the content is empty. Share it for your reference, as follows:

 <script type="text/javascript"><!--// Automatically calculates the editor base path based on the _samples directory.// This is useful 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() ;//-->//Get the length of the fck content 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('Please enter content'); return false; }}//Get fck content function GetMessageContent(str){ var oEditor = FCKeditorAPI.GetInstance(str) ; return oEditor.GetXHTML();}</script>

When there is the following config.php configuration:

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

When uploading, the quick upload will be uploaded directly to the upload directory.

Non-fast upload will be uploaded to the upload/image directory

When browsing the server

Image browsing will point to upload/image

Therefore, the pictures uploaded quickly cannot be browsed when browsing the server.

PS: Here, the editor recommends several code formatting tools to you, I believe that it can be used in future programming development:

C language style/HTML/CSS/json code formatting and beautification tools:
