JS。某鼠标滚轮事件。

添加和删除侦听事件：

 

this.initEvent = function(){var mousewheelevt=(/Firefox/i.test(navigator.userAgent))? "DOMMouseScroll" : "mousewheel"; //FF doesn't recognize mousewheel as of FF3.xif (document.attachEvent) //if IE (and Opera depending on user setting)document.attachEvent("on"+mousewheelevt, this.resizeImages);else if (document.addEventListener) //WC3 browsersdocument.addEventListener(mousewheelevt, this.resizeImages, false);};this.removeEvent = function(){var mousewheelevt=(/Firefox/i.test(navigator.userAgent))? "DOMMouseScroll" : "mousewheel"; //FF doesn't recognize mousewheel as of FF3.xif (document.detachEvent) //if IE (and Opera depending on user setting)document.detachEvent("on"+mousewheelevt, this.resizeImages);else if (document.removeEventListener) //WC3 browsersdocument.removeEventListener(mousewheelevt, this.resizeImages);};
