Is there a way to get work .keypress on a div element like this?:
有没有办法让 .keypress 像这样在 div 元素上工作?:
<html>
<body>
<script type="text/javascript">
<!--
$('#idtext').keypress(function(event) {
var keyCode = event.keyCode;
$('#idtext').text(function(i, text) {
return text + String.fromCharCode(keyCode);
});
});
// -->
</script>
<div id="idtext"></div>
</body>
</html>

Yes: you need to add a tabindexattribute to the <div>to allow it to receive the focus.
是的:您需要向 中添加一个tabindex属性<div>以允许它接收焦点。
<div id="idtext" tabindex="1"></div>
Also, the property you want for the character code of the text entered in a keypress event is which, not keyCode.
此外,您想要在按键事件中输入的文本的字符代码的属性是which,而不是keyCode。
Finally, the HTML comment tags inside the <script>element are unnecessary in all modern browsers.
最后,<script>元素内的 HTML 注释标签在所有现代浏览器中都是不必要的。
