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。
