jQuery Event Keypress:按下了哪个键? [英] jQuery Event Keypress: Which key was pressed?
本文介绍了jQuery Event Keypress:按下了哪个键?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
With jQuery, how do I find out which key was pressed when I bind to the keypress event?
$('#searchbox input').bind('keypress', function(e) {});
I want to trigger a submit when ENTER is pressed.
[Update]
Even though I found the (or better: one) answer myself, there seems to be some room for variation ;)
Is there a difference between keyCode
and which
- especially if I'm just looking for ENTER, which will never be a unicode key?
Do some browsers provide one property and others provide the other one?
解决方案
Actually this is better:
var code = e.keyCode || e.which;
if(code == 13) { //Enter keycode
//Do something
}
