如何在Windows Mobile 5浏览器中检测JavaScript按键事件？

Question

I have a text box on a webpage which upon pressing the enter key, it should do something. 我在网页上有一个文本框，按Enter键后，它应该会执行某些操作。 So I detect the key code for the Enter key onkeyup. 因此，我检测到Enter键onkeyup的键代码。

My issue is, it appears that any JavaScript key events (keypress, keydown, keyup) do not work in the Windows Mobile 5 IE browser? 我的问题是，似乎任何JavaScript键事件（键，键按下，键按下）在Windows Mobile 5 IE浏览器中均不起作用？ I've tried onlblur as well. 我也尝试过onlblur。 I'm looking for a JavaScript solution ideally. 我正在寻找理想的JavaScript解决方案。

I've seen some suggestions on the web about setting KeyPreview to true, but that appears to be only for Windows Forms. 我已经在网上看到一些有关将KeyPreview设置为true的建议，但这似乎仅适用于Windows窗体。

HTML example (seems to work fine in situations other than this): HTML示例（在其他情况下似乎可以正常工作）：

<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
    function isEnterPressed(){
        if (window.event.keyCode == 13) {
                alert("Enter was pressed!");
            }
        }

</script>
</head>
<body onload="document.getElementById('txtEntry').focus();">
    <span>
        Press the enter key...if enter is detected, message will display below.
    </span>
    <br />
    <input type="text" id="txtEntry" onkeyup="isEnterPressed()">
</body>
</html>

If this is really Windows Mobile 5 there is no way to get JavaScript events for key presses as JScript in Windows Mobile 5 does simple NOT support any key event. 如果这确实是Windows Mobile 5，则无法获取按键的JavaScript事件，因为Windows Mobile 5中的JScript确实不支持任何按键事件。 Javascript Key event support started with Windows Mobile 6 (AKU 6.1.4 or so). Windows Mobile 6（AKU 6.1.4左右）开始支持Javascript密钥事件。

There are third party 'browser' like Intermec Browser, NaurTecc and zetakey that either support javascript key events or provide a workaround using special META tags or setup that is captured by the browser 'wrapper'. 有第三方“浏览器”，例如Intermec浏览器，NaurTecc和zetakey，它们支持javascript键事件或使用特殊的META标签或由浏览器“包装器”捕获的设置来提供解决方法。
