当我单击按钮(例如输入类型=“按钮”class =“test”), 我想显示样式表类名称。单击按钮,显示CSS类名称
我已经试过这样。
$(this).get(0).style.name
但我只得到未定义的消息。 请让我知道如何得到它。

让我告诉你我的编码。
<html xmlns="http://www.w3.org/1999/xhtml">

<script type="text/javascript" src="jquery-1.6.4.js"></script>

<script>
$(document).ready(function(){
var CurrentTextBoxID = "";
// toggles the keyboard to show or hide when link is clicked
$(":text").focus(function(e) {
CurrentTextBoxID = this.id;
var top = ($(window).height() - $('#keyboard').height()) - 25;
var left = ($(window).width() - $('#keyboard').width())/2;
//alert(CurrentTextBoxID + " focus In");
$('#keyboard').css(
{
"left": left+"px",
"top": top+"px"
}
).toggle();
$('#keyboard').show();
});
//$(":text").focusout(function() {
$(":text").focusout(function() {
alert($(this).attr('class'));
if($(this).attr('class') != "testClass"){
$('#keyboard').hide();
}
});
// function thats called when any of the keys on the keyboard are pressed
$("#keyboard input").bind("click", function(e) {
$('#'+CurrentTextBoxID).replaceSelection($(this).val(), true);
});
});
</script>

</tr>

</div>
</td>

</table>
</div>
</form>
</body>
</html>
当我使用此代码,
alert($(this).attr('class'));
我还是得到了一个未定义的消息。 请再次指导我,谢谢大家。
