Chr*_*isP 5 keyboard jquery events
我有以下 jQuery 函数
jQuery.fn.integerMask =
function () {
return this.each(function () {
$(this).keydown(function (e) {
var key = (e.keyCode ? e.keyCode : e.which);
// allow backspace, tab, delete, arrows, numbers and keypad numbers ONLY
return (
key == 8 ||
key == 9 ||
key == 46 ||
key == 37 ||
key == 39 ||
(key >= 48 && key <= 57) ||
(key >= 96 && key <= 105));
);
});
});
};
用于输入数字。问题是 SHIFT+8 会导致输入星号 * 字符。似乎允许将“8”键与 SHIFT 组合使用。如何防止 SHIFT+8 被接受并插入“*”字符？
