content相当于你例子中的FCKeditor1。 
 
//获取格式化的编辑器内容 
function getEditorContents(){ 
var oEditor = FCKeditorAPI.GetInstance(“content”); 
alert(oEditor.GetXHTML(true)); 
} 
//向编辑器插入指定代码 
function insertHTMLToEditor(codeStr){ 
var oEditor = FCKeditorAPI.GetInstance(“content”); 
if (oEditor.EditMode==FCK_EDITMODE_WYSIWYG){ 
oEditor.InsertHtml(codeStr); 
}else{ 
return false; 
} 
} 
//统计编辑器中内容的字数 
function getLength(){ 
var oEditor = FCKeditorAPI.GetInstance(“content”); 
var oDOM = oEditor.EditorDocument; 
var iLength ; 
if(document.all){ 
iLength = oDOM.body.innerText.length; 
}else{ 
var r = oDOM.createRange(); 
r.selectNodeContents(oDOM.body); 
iLength = r.toString().length; 
} 
alert(iLength); 
} 
//执行指定动作 
function ExecuteCommand(commandName){ 
var oEditor = FCKeditorAPI.GetInstance(“content”) ; 
oEditor.Commands.GetCommand(commandName).Execute() ; 
} 
//设置编辑器中内容 
function SetContents(codeStr){ 
var oEditor = FCKeditorAPI.GetInstance(“content”) ; 
oEditor.SetHTML(codeStr) ; 
} 
fckeditor常用Js,获取fckeditor内容,统计fckeditor字数,向fckeditor写入指定代码
