For IE changed its User-Agent, YUI(2.9) need a surgery.
Modify yahoo-dom-event.js: Find this: YAHOO.env.parseUA, then at last add something that tell YAHOO.env.ua now is undering IE 11. like this:
if (g.ie == 0 && c.indexOf('Trident') != -1){ g.ie = 11; }
Modify editor.js: Find the
_setInitialContent
function, and after the if-branch that includes "BackCompat", add this:this.browser = YAHOO.env.parseUA();
then just in the following if-branch (
if (this.browser.ie || this.browser.webkit || this.browser.opera || (navigator.userAgent.indexOf('Firefox/1.5') != -1))
): add this:if (this.browser.ie == 11) { this.browser.ie = 0; }
Hope Works, Good Luck!
