obj.addEventListener('DOMMouseScroll',mouseWheel,false);
obj.addEventListener("mousewheel",mouseWheel,false);
}

I am developing a web app and all ui element will be not in a correct order if user zoom in / zoom out . So, are there any way to prevent it? I have think of some way to do it but is it possible ?
我正在开发一个 Web 应用程序，如果用户放大/缩小，所有 ui 元素的顺序都将不正确。那么，有没有什么办法可以预防呢？我已经想到了一些方法来做到这一点，但有可能吗？
1) Get the screen resolution of the user. When the window size is change (either width or height), return the window width/height to screen width /height.
1) 获取用户的屏幕分辨率。当窗口大小发生变化（宽度或高度）时，将窗口宽度/高度返回到屏幕宽度/高度。
2) bind the mouse scroll event or keyboard event to nothing. (Refer to above demo code) , but what if the user click on the browser and select zoom in ?
2) 将鼠标滚动事件或键盘事件绑定到空。（参考上面的演示代码），但是如果用户点击浏览器并选择放大呢？
Thanks
谢谢

var zoomlevel=1;
$("body").dblclick(function(ev) {
zoomlevel = zoomlevel == 1 ? 2 : 1;
$(this).css({
"-moz-transform":"scale("+zoomlevel+")",
"-webkit-transform":"scale("+zoomlevel+")",
"-o-transform":"scale("+zoomlevel+")",
"-ms-transform":"scale("+zoomlevel+")"
});
});
