Capture an Enter Key Pressed anywhere on the page
提问by Adam
I need to capture an Enter Key press at any time anywhere on a logon page. It will initiate a logon attempt.
我需要随时随地在登录页面上的任何位置捕获 Enter 键按下。它将启动登录尝试。
Using jQuery, how would I accomplish this? And would I link it to the body tag?
使用 jQuery，我将如何做到这一点？我会把它链接到 body 标签吗？

$(document).keypress(function(e) {
if(e.which == 13) {
// enter pressed
}
});

The keydown event is fired when a key is pressed down.
The keypress event is fired when a key is pressed down and that key normally produces a character value.
当按下某个键时会触发 keydown 事件。
当一个键被按下并且该键通常会产生一个字符值时会触发 keypress 事件。
$(document).keydown( function(event) {
if (event.which === 13) {
// login code here
}
});
