如何使用 jQuery 检测键盘上的 Enter 键?
我想用jQuery检测用户是否按下了Enter.
I would like to detect whether the user has pressed Enter using jQuery.
这怎么可能?需要插件吗?
How is this possible? Does it require a plugin?
看来我需要使用 keypress()方法.
It looks like I need to use the keypress() method.
我想知道是否有人知道该命令是否存在浏览器问题 - 比如有没有我应该知道的浏览器兼容性问题?
I wanted to know if anyone knows if there are browser issues with that command - like are there any browser compatibility issues I should know about?
推荐答案
jQuery 的全部意义在于您不必担心浏览器的差异.我很确定您可以安全地使用 enter 在所有浏览器中设置为 13.因此，考虑到这一点，您可以这样做:
The whole point of jQuery is that you don't have to worry about browser differences. I am pretty sure you can safely go with enter being 13 in all browsers. So with that in mind, you can do this:
$(document).on('keypress',function(e) {
if(e.which == 13) {
alert('You pressed enter!');
}
});
