百度编辑器的内容改变事件监听bug

先贴上我的初始化代码,可能是用法问题冤枉了百度编辑器,如果是我的用法有问题欢迎大侠们指正

console.log('全屏模式:'+mode);
}) return editor;
} var editor = createEditor(); $('#addLinkTest').click(function(){
editor.execCommand("link",{

}); }); $('#addImgTest').click(function(){ editor.execCommand("insertImage",{

}); });
});
//init.invokeAll();
</script> </body>
</html>

提供的事件监听是这样的:

//事件
editor.addListener("contentChange",function(){
console.log('内容改变:'+editor.getContent());
});

一般的字符都可以监听,但是@#¥%……这些字符的输入是监听不到的。实现原理应该是监听的键盘事件,百度的牛人们呀,你们难道不知道对于这些特殊字符是监听键盘的keypress和keyup是监听不到的吗....

好吧那字能自己解决了。

最挫的办法就是时钟监听了,每隔几十毫秒获取一下编辑框中的内容,与之前内容比较一下,变了就触发改变事件。但是这不是理想的方案呀...

有没有好的实现方案呢,有了!想到之前看过的一个实时统计字数的小东西

什么字符都支持,好研究一下,核心到吗如下

var $textarea = $('#' + shellId + '');

var fn = function(){
alert(editor.getContent());
} if (document.all) {
$textarea.get(0).attachEvent('onpropertychange',function(e) {
fn();
});
}else{
$textarea.on('input',fn);
}

好,我们也这么玩。

但是问题来了,iframe是可编辑元素吗?支持上面的监听事件吗?

万能的网友给了我答案,能!

果断实现,结果如下:

editor.ready(function(){
$('#' + shellId + ' #edui1_toolbarbox').css('display','none');
editor.fireEvent("contentChange"); var $textarea = $('#' + shellId + '').parent().find('iframe').contents(); var fn = function(){
alert(editor.getContent());
} if (document.all) {
$textarea.get(0).attachEvent('onpropertychange',function(e) {
fn();
});
}else{
$textarea.on('input',fn);
} });
