关闭后退按钮弹出 [英] Close pop up on back button
问题描述
我想点击手机后退按钮关闭弹出窗口。我使用onhashchange实现了这个：
I want to close pop up on click of back button for mobile. I implemented this using onhashchange:
window.onhashchange = function (event) {
};
在这种情况下，如果多次打开弹出窗口，然后点击后退按钮，它会打开并且关闭模态弹出窗口。但是，我希望模式弹出窗口在第一次关闭时关闭并导航到下一页上的prev页面。
In this case, if pop up is opened multiple times then on click of back button, it opens and closes the modal pop up. But, I want modal pop up to close on first back and navigate to prev page on next back.
我也尝试使用onbeforeunload，但它会显示另一个警告离开或留在页面上。
I also tried using onbeforeunload, but it will show another alert to leave or stay on the page.
$(window).bind('beforeunload', function(e) {
return false;
});
关闭后退按钮弹出窗口并在下一页上重定向到prev页面的最佳方法是什么？
What is the best way to close the pop up on back button and redirect to prev page on next back?
推荐答案
当我测试我的答案时，bootply.com失败了。请参阅下面代码底部的内联脚本和注释。其余的只是Twitter Bootstrap样板，以便我可以在本地轻松测试。
bootply.com was down when I was testing my answer. See the inline script and comments at the bottom of the code below. The rest is just Twitter Bootstrap boilerplate so that I could easily test it locally.
