捕获“删除"消息. jQuery按键 [英] Capturing "Delete" Keypress with jQuery

问题描述

当使用jQuery文档中的示例代码作为keypress事件处理程序时，我无法捕获 Delete 键.在FireFox中按下 Delete 键时，下面的代码片段将记录0:

When using the example code from the jQuery documentation for the keypress event handler, I'm unable to capture the Delete key. The snippet below is going to log 0 when the Delete key is pressed in FireFox:

$(document).keypress(function(e) {
    console.log(e.which);       
});

似乎有一种方法可以捕获 Delete 键，但这是一个模棱两可的术语，因此Google并没有提供太多帮助.

Seems there's gotta be a way to capture the Delete key, but it's an ambiguous term so Google isn't proving to be much help with it.

推荐答案

您不应使用keypress事件，而应使用keyup或keydown事件，因为keypress事件是用于实际的(可打印的) ) 人物. keydown的处理级别较低，因此它将捕获所有非打印键，例如 delete 和 enter .

You shouldn't use the keypress event, but the keyup or keydown event because the keypress event is intended for real (printable) characters. keydown is handled at a lower level so it will capture all nonprinting keys like delete and enter.
