使用jQuery模拟Keypress [英] Simulate Keypress With jQuery

问题描述

使用jQuery，如何在点击链接时模拟（触发？）KeyPress？例如，当用户点击以下链接时：

Using jQuery, how can I simulate (trigger?) a KeyPress when a link is clicked? For example, when a user clicks the following link:

<a id="clickforspace" href="#">Click Here</a>

然后，通过点击链接，就好像他们按下键盘上的空格键一样。

Then, by clicking the link, it would be as if they pressed the "spacebar" on their keyboard.

像这样，我假设：

$("#clickforspace").click(function(e) { 
    e.preventDefault(); 
    //... Some type of code here to initiate "spacebar" //
                                      });

关于如何实现这一目标的任何想法？

Any ideas on how to achieve this?

推荐答案

来自jQuery的keypress事件是为了做这种工作。您可以通过将字符串keypress传递给.trigger（）来触发事件。但是更具体地说，您实际上可以传递一个jQuery.Event对象（将类型指定为keypress）并提供您想要的任何属性，例如键代码是空格键。

The keypress event from jQuery is meant to do this sort of work. You can trigger the event by passing a string "keypress" to .trigger(). However to be more specific you can actually pass a jQuery.Event object (specify the type as "keypress") as well and provide any properties you want such as the keycode being the spacebar.
