篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了模式-初始化分支相关的知识，希望对你有一定的参考价值。
var MYAPP = {};
MYAPP.event = {
addListener: null,
removeListener: null
};
if (typeof window.addEventListener === ‘function‘) {
MYAPP.event.addListener = function(el, type, fn) {
el.addEventListener(type, fn, false);
};
MYAPP.event.removeListener = function(el, type, fn) {
el.removeListener(type, fn, false);
}
} else if (typeof window.attachEvent === ‘function‘) {
MYAPP.event.addListener = function(el, type, fn) {
el.attachEvent(‘on‘ + type, fn);
};
MYAPP.event.removeListener = function(el, type, fn) {
el.detachEvent(‘on‘ + type, fn);
};
} else {
MYAPP.event.addListener = function(el, type, fn) {
el[‘on‘ + type] = fn;
};
MYAPP.event.removeListener = function(el, type, fn) {
el[‘on‘ + type] = null;
};
};
