ie9 창닫힐 때 onunload 이벤트 안먹는 문제.

// [TR] Different listeners added for illustration
function f1() { document.write("addEventListener was used"); }
function f2() { document.write("attachEvent was used"); }

// Use this: Feature Detection
if(window.addEventListener) {
    window.addEventListener("load", f1, false);
} else if(window.attachEvent) {
    window.attachEvent("onload", f2);
}

Try It!

IE9 Output: addEventListener was used

저런식으로 하면 된다지만..


사실. onunload는 여전히 안먹는다.


결국


브라우저의 셋팅을 만저주어야만 사용가능하다.


ie7,ie8은 onunload가 enable, ie9는 disable로 되어 있어서 그렇다

IN IE 9 browser  shut down behavior is disabled, that means that window.onunload event won't fire. In all browsers except IE9 this behavior is enabled by default.http://www.grouppolicy.biz/2011/03/internet-explorer-9-group-policy-settings/
