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?

The whole point of jQuery is that you don't have to worry about browser differences.

(jQuery的重点在于您不必担心浏览器差异。)

I am pretty sure you can safely go with enter being 13 in all browsers.

(我很确定你可以放心地在所有浏览器中输入 13。)

So with that in mind, you can do this:

(所以考虑到这一点，你可以这样做：)

$(document).on('keypress',function(e) {
    if(e.which == 13) {
        alert('You pressed enter!');
    }
});
