Ano*_*oop 3 javascript jquery keypress onkeyup
下面的方法返回来自AZ和0-9的任何键,当我按下shift键+ 4时,它返回相同的代码52.
function keyUpEvent(e)//onkeyup event
{
var chr = String.fromCharCode(e.keyCode);//converts the keycode into a character
alert(chr);//alerts the character
}

但是当按下shift键组合的相应键时,我需要显示$或%.
我会用这样的东西:
$(function () {
$(document).on('keyup keydown keypress', function (event) {
if (event.keyCode == 52 && event.shiftKey) {
alert('foo');
}
});
});
