FCK常用Js,获取FCK内容,统计FCK字数,向FCK写入指定代码

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) ;
}
