我可以触发点击事件onload [英] can I trigger click event onload

问题描述

我的页面中有锚标记。我喜欢触发click事件onload。这意味着我想用新标签打开这个页面http://XXXXX.com。因为我不想弹出阻挡者。反正有没有这样做？

I am having anchor tag in my page. I like to trigger click event onload . Which means I wanna open this page "http://XXXXX.com" with new tab. Because I don't wanna popup blockers. Is there anyway to do this?

锚定器如下所示

id="add_redirect"
href="http://XXXXX.com"
target="_blank"

推荐答案

如果您的目标是在页面加载时绕过弹出窗口阻止程序，则触发单击事件合成可能不会起作用。浏览器非常聪明，可以知道用户生成的点击何时调用点击函数DOM元素（在那些浏览器上甚至可以工作）。示例： http://jsbin.com/avibi3/3 ， http://jsbin.com/avibi3/4

If your goal is to bypass pop-up blockers on page load, triggering the click event synthetically probably won't work. Browsers are smart enough to know when a click is user-generated vs. when you've called the click function on the DOM element (on those browsers were that even works). Examples: http://jsbin.com/avibi3/3, http://jsbin.com/avibi3/4

使用jQuery的触发器机制当然不会这样做，因为它根本没有真正触发点击事件;它只是触发jQuery连接的处理程序（编辑：显然，通过 onclick 属性定义的&mbsp;—参见Sukhi的回答 —但不是通过 addEventListener ）附加。如果你想做什么，Sukhi的答案会告诉你如何，虽然我总是说：如果你想要从两个不同的地方运行代码，把它放在一个函数中，并从两个不同的地方调用该函数（而不是把它放在一起）在中单击处理程序，然后模拟单击以运行代码）。 触发器的有效用例（主要与第三方脚本集成有关），但是为了从两个不同的地方运行自己的代码，这是设计问题的症状。

Using jQuery's trigger mechanism certainly won't do it, because it doesn't really trigger a click event at all; it just fires the handlers that jQuery hooked up (edit: and, apparently, ones defined via an onclick attribute — see Sukhi's answer — but not ones attached via addEventListener). If that's what you want to do, Sukhi's answer shows you how, although I always say: If you want code to be run from two different places, put it in a function, and call that function from two different places (rather than putting it in a click handler and then simulating a click just to run the code). There are valid use cases for trigger (mostly relating to integrating with third-party scripts), but for running your own code from two different places, it's a symptom of a design problem.
