如何打开然后关闭窗口而不会被弹出窗口阻止? [英] How to open and then close a window without getting blocked as a popup?

问题描述

我想指示电子商务网站中的客户通过Paypal网站进行付款. 我希望付款在新的标签/窗口中完成，这样客户就不会失去他/她所在的网页的当前状态.

I want to direct a customer in an e-commerce site to pay via Paypal's website. I would like the payment to be done in a new tab/window so the customer doesn't lose the current state of the web page he/she is at.

为了在不被阻止的情况下打开Paypal窗口，我在使用带有target ="_ blank"的锚点.除以下事实外，这一切正常运行，因为在未通过window.open()打开的窗口中window.close()无效，因此在Paypal付款后我无法将其关闭.

In order for the Paypal window to open without getting blocked, I am using an anchor with target="_blank". Which is working perfectly except for the fact, I can't close it after Paypal payment is done since window.close() doesn't work for windows that were not opened via window.open().

如何制作它，使其既不被阻止为弹出窗口，又可以稍后用JS将其关闭?

How do I make it so it is BOTH not blocked as a popup AND I am able to close it with JS later on?

推荐答案

为了在不被阻止的情况下打开Paypal窗口，我使用了具有target ="_ blank"的锚点.

这是一个选项，但是只要您在处理程序中为用户生成的事件(例如click)调用window.open，就可以打开弹出窗口.因此，只需确保从链接上的click处理程序中调用window.open(然后可以将其关闭).现代的弹出窗口阻止程序(过去几年中的任何一种)都可以阻止不是由用户事件触发的弹出窗口，而是允许那些由用户事件触发的弹出窗口.

That's one option, but as long as you call window.open from within the handler for a user-generated event (like click), you can open pop-up windows. So just make sure you call window.open from within a click handler on the link (and then you can close it). Modern pop-up blockers (anything from the last several years) block pop-ups that aren't triggered by a user event, but allow ones that are.

实时示例 | 源:

HTML:

<p><a href="#" id="target">Click to open popup</a>; it will close automatically after five seconds.</p>

JavaScript:

JavaScript:

(function() {

  document.getElementById("target").onclick = function() {
    var wnd = window.open("http://stackoverflow.com");
    setTimeout(function() {
      wnd.close();
    }, 5000);
    return false;
  };

})();
