bbcode and js event problem

[zleaf]

for example: after paste a image in ckeditor in bbcode mode, (the image is like :

<img src="​http://cksource.com/forums/images/smilies/icon_e_biggrin.gif" onclick="alert('abc')">

), then click the View Source button, error occur...

here's my way to fix this problem, hoping the official way

function purge(d){

var a=d.attributes,i,l,n; if(a){

l=a.length; for(i=0;i<l;i+=1){

n=a[i].name; if(typeof d[n]==='function'){

d[n]=null;

}

}

} a=d.childNodes; if(a){

l=a.length; for(i=0;i<l;i+=1){

purge(d.childNodes[i]);

}

}

} editor.on( 'insertHtml', function(data){

var t=document.createElement('div'); document.body.appendChild(t); t.innerHTML = data.data; purge(t); data.data = t.innerHTML; document.body.removeChild(t);

});
