editor.js，找到function BtnMouseUp()函数

if(navigator.appVersion.match(/9./i)=='9;' || navigator.appVersion.match(/8./i)=='8.' || navigator.appVersion.match(/MAXTHON/i)=='MAXTHON'){
if (element.YUSERONCLICK) eval_r(element.YUSERONCLICK + "onclick(event)");
}else{
if (element.YUSERONCLICK) eval_r(element.YUSERONCLICK + "anonymous()");
}
