window.onmousemove in IE and Firefox
提问by Honus Wagner
The purpose of the following code is that when the user is holding the SHIFT key down, some text will indicate that they are pressing it. It works great in Firefox, but IE does not acknowledge it.
以下代码的目的是当用户按住 SHIFT 键时，一些文本将指示他们正在按下它。它在 Firefox 中运行良好，但 IE 不承认它。
window.onmousemove = function(e) {
e = e || window.event;
var copyLabel = document.getElementById("<%= lblCopyEnabled.ClientID %>");
if (e.shiftKey) {
copyLabel.style.display = "inline";
ob_copyOnNodeDrop = true;
}
else {
copyLabel.style.display = "none";
ob_copyOnNodeDrop = false;
}
}
Advice is appreciated.

Despite what the MSDN docs say, onmousemovedoesn't work when applied to the windowobject. It should work in all browsers if you apply it to the documentobject instead:
尽管 MSDN 文档说了什么，onmousemove但在应用于window对象时不起作用。如果将其应用于document对象，它应该适用于所有浏览器：
document.onmousemove = function(e) {
e = e || window.event;
var copyLabel = document.getElementById("<%= lblCopyEnabled.ClientID %>");
if (e.shiftKey) {
copyLabel.style.display = "inline";
ob_copyOnNodeDrop = true;
}
else {
copyLabel.style.display = "none";
ob_copyOnNodeDrop = false;
}
}
