问题描述
使用 jQuery，如何在单击链接时模拟(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，通过单击链接，就好像他们按下了键盘上的空格键".
Then, by clicking the link, it would be as if they pressed the "spacebar" on their keyboard.
我假设是这样的:
$("#clickforspace").click(function(e) {
e.preventDefault();
//... Some type of code here to initiate "spacebar" //
});
关于如何实现这一点的任何想法?
Any ideas on how to achieve this?
推荐答案
来自 jQuery 的 keypress 事件旨在完成此类工作.您可以通过将字符串keypress"传递给 .trigger() 来触发事件.然而，更具体地说，您实际上也可以传递一个 jQuery.Event 对象(将类型指定为keypress")并提供您想要的任何属性，例如作为空格键的键码.
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.
