onKeyUp没有为IE中的ESC触发 [英] onKeyUp not firing for ESC in IE
本文介绍了onKeyUp没有为IE中的ESC触发的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个页面，当按下 Esc 时，我必须关闭对话框。我为此任务编写了以下简化代码示例：
I have a page where I have to close a dialog when Esc is pressed. I wrote the following simplified code example for this task:
<html>
<head>
<script language="JavaScript">
function keyUpExample() {
alert('on' + event.type + ' event fired by ' + '"' + event.srcElement.id + '" ' + ' ' + event.which)
}
</script>
</head>
<body id="myBody" onkeyup="keyUpExample()">
Trying keyUp event: Press any key...
</body>
</html>
这在Chrome下可以正常使用，但在IE 7下无效。是否有任何解决方法可以订购应对这个问题？
This works as expected under Chrome but is NOT working under IE 7. Is there any workaround on order to cope this problem?

推荐答案
重要事件不必被身体抓住，但文档或窗口可以跨浏览器工作。此外，keyCode为keyup或down事件返回正确的值。
Key events don't have to be caught by the body, but document or window works across browsers. Also, keyCode returns the correct value for keyup or down events.
<!doctype html>
<html lang="en">
<head>
<meta charset= "utf-8">
<title>Small Page</title>
<html>
<head>
<script>
function keyUpExample(e){
e=e || window.event;
var who= e.target || e.srcElement;
alert(e.type+' caught at '+who.nodeName+ ': key #'+e.keyCode)
}
window.onload=function(){
document.onkeyup= keyUpExample;
document.body.onkeyup= keyUpExample;
}
</script>
</head>
<body>
Trying keyUp event: Press any key...
</body>
</html>
