    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) ;
}
