问题描述
我有以下示例代码,当div处于焦点并按下一个键时,该代码应该弹出警报。这是我在IE 7中所期待的,但在Firefox 3.5.5中却没有。我做错了什么?
I have the following example code, which should pop up an alert when the div is in focus and a key is pressed. This does what I expect in IE 7, but not in Firefox 3.5.5. What am I doing wrong?
<html>
<head>
<title>JS test</title>
<script type="text/javascript" src="jquery-1.3.2.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$("#testdiv").keydown(function(event) {
alert("Pressed " + event.keyCode);
});
});
</script>
<style type="text/css">
#testdiv
{
width: 50;
height: 50;
background-color: red;
}
</style>
</head>
<body>
<div id="testdiv"></div>
</body>
</html>
编辑:我刚刚尝试替换 keydown
与 keypress
和 keyup
,那些也不起作用。顺便说一下,我也确保我的找到你输入设置被关闭,以防万一。
EDIT: I've just tried replacing keydown
with keypress
and keyup
and those don't work either. Incidentally, I also made sure that my "Find as you type" setting is turned off just in case.
推荐答案
你需要给div一个tabindex,以便它可以得到焦点。
You need to give the div a tabindex so it can receive focus.
<div id="testdiv" tabindex="0"></div>
