Is there a way to get work .keypress on a div element like this?:
<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>
回答1:
Yes: you need to add a tabindex attribute to the <div> to allow it to receive the focus.
<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.
Finally, the HTML comment tags inside the <script> element are unnecessary in all modern browsers.
