代码如下:
function checkFCK(key)
{
var oEditor=FCKeditorAPI.GetInstance(key);
var content=oEditor.GetXHTML(true);
content=content.replace(/ /g,"");
content=content.replace(/\s/g,"");
content=content.replace(/ /g,"");
content=content.replace(/
content=content.replace(/
<\/p>/g,"");
content=content.replace(/
<\/div>/g,"");
if(content==null||content==""){
oEditor.SetHTML("");
return false;
}
return true;
}
if(content==null||content==""){
oEditor.SetHTML("");
return false;
}
return true;
}
形式2：
代码如下:
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 ;
}
return iLength
}
