Javascript仅适用于IE Quirks，7以及Chrome和Firefox。在 IE 8 或 9 标准中不起作用

Question

我的代码使许多划分看起来围绕平面上不可见的水平轴运行。它是如何工作的:它触发一个mouseevent监听器onMouseDown，并捕获用户光标相对于窗口的X。onMouseUp是由setTimeout函数模拟的，它在90毫秒后被调用，它做同样的事情，然后减去两个值来确定旋转的距离和方向。

我的问题是:为什么它在FF, Chrome, IE怪癖和IE 7标准中正常工作，而不是IE 8标准或IE 9标准?

IE8:模型崩溃，分区漂浮到包含边界划分之外。IE9: JS没有任何响应

我不知道什么可能或可能不相关的你，所以我包括整个脚本。如果你愿意，你可以忽略最长的函数

iScroll()

@RyanStortz。尝试用这种方式注册事件:

var isMouseCaptured=false;
function i_boundary_mousedown(ev) {
    isMouseCaptured=true;
    iScrollListen("Down");
}
function doc_mousemove(ev) {
    if(isMouseCaptured) {
        ev=ev||event;
        myX=ev.clientX;
        myY=ev.clientY;
    }
}
function doc_mouseup(ev) {
    if(isMouseCaptured) {
        isMouseCaptured=false;
        ev=ev||event;
        myX=ev.clientX;
        myY=ev.clientY;
    }
}
var i_boundaryObj=document.getElementById('I_BOUNDARY');
if(window.addEventListener) {
    i_boundaryObj.addEventListener('mousedown',i_boundary_mousedown,false);
    document.addEventListener('mousemove',doc_mousemove,false);
    document.addEventListener('mouseup',doc_mouseup,false)
}
else if(window.attachEvent) {
    i_boundaryObj.attachEvent('onmousedown',i_boundary_mousedown)
    document.attachEvent('onmousemove',doc_mousemove);
    document.attachEvent('onmouseup',doc_mouseup)
}
else ;//

为DIV添加类"I_BOUNDARY" id属性"I_BOUNDARY"并删除onmousedown属性
