JS集成fckeditor及判斷內(nèi)容是否為空的方法

字號(hào):


    這篇文章主要介紹了JS集成fckeditor及判斷內(nèi)容是否為空的方法,涉及fckeditor的設(shè)置及頁(yè)面元素的操作技巧,并分析了php環(huán)境下配置文件上傳的注意事項(xiàng),需要的朋友可以參考下
    本文實(shí)例講述了JS集成fckeditor及判斷內(nèi)容是否為空的方法。分享給大家供大家參考,具體如下:
    <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內(nèi)容的長(zhǎng)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('請(qǐng)輸入內(nèi)容');
     return false;
     }
    }
    //取fck內(nèi)容
    function GetMessageContent(str)
    {
     var oEditor = FCKeditorAPI.GetInstance(str) ;
     return oEditor.GetXHTML();
    }
    </script>
    當(dāng)有以下config.php配置時(shí):
    $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'] ;
    上傳時(shí),快速上傳將直接上傳到upload目錄下
    非快速上傳將傳到upload/image目錄下
    瀏覽服務(wù)器時(shí)圖片瀏覽將指向upload/image所以快速上傳的圖片在瀏覽服務(wù)器時(shí),不能瀏覽到。
    希望本文所述對(duì)大家JavaScript程序設(shè)計(jì)有所幫助。
