How to trigger Ctrl+C key event with jQuery?
提问by Angelus
I want to simulate Ctrl+Cto copy the text from a page. I first tried this:
我想模拟Ctrl+C从页面复制文本。我首先尝试了这个：
$('#codetext').click( function() {
$("#codetext").trigger({
type: 'keydown',
which: 99
});
}
HTML:
HTML：
<input type='text' id='codetext'>
I have also tried using $(this)instead of the selector, but the input element also has focus on it, so it doesn't run.
我也试过使用$(this)代替选择器，但输入元素也关注它，所以它不会运行。

not sure how to trigger ctrl+c, but there's a JQuery clipboard plugin that may be of some use:
不知道如何触发 ctrl+c，但有一个 JQuery 剪贴板插件可能会有用：

You cannot trigger a cut, copy or paste programmatically in JavaScript (at least, not in most browsers). These actions can only come from the user. If you need to do this you'll need some kind of hack like the Flash-based things in other answers but I wouldn't even rely on them working forever.
您不能在 JavaScript 中以编程方式触发剪切、复制或粘贴（至少在大多数浏览器中不是）。这些操作只能来自用户。如果你需要这样做，你将需要一些类似其他答案中基于 Flash 的东西的 hack，但我什至不会依赖它们永远工作。
