在Stackoverflow上的关闭弹出窗口中插入链接到欺骗

问题描述

我正在研究一些代码，在SO关闭问题弹出窗口中插入一个欺骗的链接：

I'm working on some code to insert a link to a dupe in the SO close question popup:

当您在文本框中手动插入问题的链接时会发生什么JS开始并提取属于URL的问题。但是，当我使用javascript（Chrome扩展程序）将URL插入文本框时，SO javascript从未启动以检索问题。我用来插入欺骗网址的代码是：

What happens when you manually insert a link to a question in the textbox is that some JS kicks in and fetches the question belonging to the URL. However when I insert an URL using javascript (Chrome extension) into the textbox the SO javascript never kicks in to retrieve the question. The code I am using to insert the URL of the dupe is:

$(document).on('click', '.cvhelper-dupelist li', function() {
  var url = $('a', this).attr('href');
  var $dupeBox = $('#duplicate-question');

  $dupeBox.val(url);
});

上面的代码成功地在文本框中插入了链接，但由于某种原因，SO javascript从未踢过检索问题。

The above code successfully inserts the link in the textbox, however for some reason the SO javascript never kicks in to retrieve the question.

我也尝试过以下措施，但可能无法使用：

I've also tried the following to maybe force it to no avail:

$dupeBox.change();

和

$dupeBox.keyup();

要测试发生了什么，你可以打开关闭随机弹出（如上所述）随机问题并运行：

To test what is happening you could open up the close as dupe popup (as above) of a random question and run:

$('#duplicate-question').val('http://stackoverflow.com/questions/8028957/headers-already-sent-by-php');

。

推荐答案

我想我想出了一种方法，但它相当脆弱：

I think I figured out one way, but it's rather fragile:

$dupeBox.data('events').keydown[1].handler({keyCode: 13})

此触发器此元素的第二个keydown事件处理程序。并为存根事件对象提供了一个keyCode。

This triggers the second keydown event handler of this element. And gives a keyCode for the stubbed event object.

更新

找到了更好的方法：

你可以构建一个对象：

var e = jQuery.Event("keydown", { keyCode: 64 });

并使用此对象触发事件：

And trigger the event with this object:

$dupeBox.trigger(e)

问题是SO代码检查事件对象中是否有东西：

The problem was that the SO code checked whether there was something in the event object:

e(d).keydown(c).bind("paste", null, function(a) {
  a.which || c(this)
})
