Javascript只適用於IE Quirks，7以及Chrome和Firefox。在IE 8或9中不起作用標準

Question

我的代碼使得多個分區圍繞平面上不可見的水平軸進行軌道運行。它是如何工作的：它觸發onMouseDown的mouseevent監聽器，並捕獲用戶相對於窗口的光標的X. onMouseUp由一個稱爲90毫秒後的setTimeout函數模擬，它執行相同的操作，然後減去這兩個值以確定旋轉的距離和方向。

我的問題是：爲什麼它在FF，Chrome和IE怪癖和IE 7標準中正常工作，但沒有IE 8標準或IE 9標準？

IE8：該模型發生故障，並且該分區離開包含邊界分區。 IE9：無論如何JS都沒有迴應。

下面的內容包括頁面上的JavaScript的全部，它可以發現@http://electrifiedpulse.com/360.html：

我不知道什麼可能會或可能不會與你有關的，所以我包括整個腳本。如果你想你可以忽略最長的功能，

iScroll()

@RyanStortz。嘗試在此滿耳註冊事件：

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 ;// 

添加DIV帶班 「I_BOUNDARY」 ID屬性 「I_BOUNDARY」，並刪除onmousedown事件屬性。
