fckeditor中键盘事件的问题
我使用fckeditor做在线编辑，用户输入Enter键则自动提交，并清空编辑器的内容。我捕捉了onkeydown或onkeyup事件，判断event.keyCode==13,则调用oEditor.Commands.GetCommand( "NewPage" ).Execute()，清空编辑器，运行时很奇怪，就第一次Enter键正确执行了onkeyup事件，接下来就再也没有触发onkeyup事件。。不知为什么？如果不执行“NewPage”的命令，每次enter键都能触发键盘事件，换用oEditor.SetHTML("")来清空，结果也一样，都只有第一个Enter键有用。。请各位帮忙看看什么原因？以下时代码
<script type="text/javascript" src="fckeditor/fckeditor.js"> </script>
<script type="text/javascript">
function FCKeditor_OnComplete( editorInstance )
{
editorInstance.EditorDocument.attachEvent("onkeydown", editor_keydown);
editorInstance.EditorDocument.attachEvent("onkeyup", editor_keyup);
}
function editor_keydown()
{
var oEditor = FCKeditorAPI.GetInstance('inputmsg') ;
var keycode = oEditor.EditorWindow.event.keyCode;
if(keycode==13) {
}
}
function clearInput()
{
var oEditor = FCKeditorAPI.GetInstance('inputmsg') ;
oEditor.Commands.GetCommand( "NewPage" ).Execute(); // oEditor.SetHTML("") ;
}
function editor_keyup()
{
var oEditor = FCKeditorAPI.GetInstance('inputmsg') ;
var keycode = oEditor.EditorWindow.event.keyCode;
if(keycode==13) {
clearInput();
}
}
