在IE8中处理javascript键盘输入(Handle javascript keyboard input in IE8)

在IE8中处理javascript键盘输入(Handle javascript keyboard input in IE8)

我有这个Javascript，它在IE11和Chrome中运行良好，但我需要在IE8中运行它！

document.onkeydown = checkKey function checkKey(e) { e = e || windows.event; if (e.keyCode == "39") { window.alert("RIGHT"); } else if (e.keyCode == "37") { window.alert("LEFT"); } }

为什么它在IE8中不起作用？

I have this Javascript, which is working fine in IE11 and Chrome, but I need to get it working in IE8!

document.onkeydown = checkKey function checkKey(e) { e = e || windows.event; if (e.keyCode == "39") { window.alert("RIGHT"); } else if (e.keyCode == "37") { window.alert("LEFT"); } }

Why does it not work in IE8?

最满意答案

您的代码中有拼写错误：

e = e || windows.event;

应该：

e = e || window.event;

You have a typo in your code:

e = e || windows.event;

should be:

e = e || window.event;
