这篇文章主要介绍了JS集成fckeditor及判断内容是否为空的方法,涉及fckeditor的设置及页面元素的操作技巧,并分析了php环境下配置文件上传的注意事项,需要的朋友可以参考下

本文实例讲述了JS集成fckeditor及判断内容是否为空的方法。分享给大家供大家参考，具体如下：

<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();

}

</script>

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。

希望本文所述对大家JavaScript程序设计有所帮助。
