Question

我的代码使得许多分区看起来围绕平面上不可见的水平轴进行轨道运行。工作原理：它触发onMouseDown上的mouseevent监听器，并捕获用户光标相对于窗口的X. onMouseUp由setTimeout函数模拟，该函数在90毫秒后调用，它执行相同的操作，然后减去这两个值以确定旋转的距离和方向。

我的问题是：为什么它在FF，Chrome和IE Quirks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，分裂在包含边界分区之外浮动。 IE9：JS无论如何都没有回应。

以下内容包含页面上的整个javascript，可在@ http://electrifiedpulse.com/360.html找到：

<script type=text/javascript>
var objectCount = 8; var pixel = new Array(); var size = new Array();
var command = "Stop"; var panel = new Array('0','Back','Front','Front','Back','Front','Back','Front','Back'); 
var quadrant = new Array(); var originalSize = 50;
var WindowWidth = 360; var WindowWidthHalf = WindowWidth/2; var sTime=0; var s1=0; var scrollSpeed;

var myX, myY;
function myMove(evt) {
  if (window.event){myX = event.clientX;myY = event.clientY;}
  else{myX = evt.clientX;myY = evt.clientY;}
}

document.onmousemove = myMove;
if (!window.event) {document.captureEvents(Event.MOUSEMOVE);}

function iScrollStop(){

document.getElementById('I_CONTROLS').innerHTML = sTime + ", " + scrollSpeed;

我不知道与您有什么关系或不关联，所以我包含了整个脚本。如果你想要，你可以忽略最长的功能，

iScroll()

@RyanStortz。尝试以此方式注册事件：

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 ;//

使用类“I_BOUNDARY” id 属性“I_BOUNDARY”添加DIV并删除 onmousedown 属性。

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
