How to setup javascript redirect to send user to back page? see code
提问by user187580
With onclick="history.go(-1);return false;"user can navigate to back pages. But if I want to put a confirm method before it takes user to the back. How would I do that?
随着onclick="history.go(-1);return false;"用户可以导航到后页。但是如果我想在将用户带到后面之前放置一个确认方法。我该怎么做？
I think it can be achieved by doing something like below but I am not sure how to redirect user to back page?
我认为可以通过执行以下操作来实现，但我不确定如何将用户重定向到后退页面？
$('.clickme').click(function() {
if(confirm("Are you sure you want to navigate away from this page?"))
{
//window.close();
// how to redirect to history.go(-1) ??
}
return false;
});
UPDATE
更新
Also is there any way I can check if history has some values in it or is empty? So that I can alert user if is empty?
还有什么方法可以检查历史记录中是否有一些值或为空？这样我就可以在为空时提醒用户？

It's quite as simple as you think it is:
它和你想象的一样简单：
$('.clickme').click(function() {
if(confirm("Are you sure you want to navigate away from this page?"))
{
history.go(-1);
}
return false;
});

$('.clickme').click(function() {
if(history.length != 0)
{
if(confirm("Are you sure you want to navigate away from this page?"))
{
document.location.replace(document.referrer)
}
return false;
}
alert("No history found");
return false;
});

<script type="text/javascript" language="javascript">
function goBack()
{
window.history.back()
}
window.onkeyup = function (e)
{
if (e.keyCode == 27) window.history.back();
}
</script>
Add above code in your head section of page. Here whenever user press Escbutton then he will be redirected to previous view page and if we want to add this logic on back button press then just call goback()on click event.
在页面的头部部分添加上面的代码。在这里，每当用户按下Esc按钮时，他将被重定向到上一个视图页面，如果我们想在后退按钮按下时添加此逻辑，则只需调用goback()单击事件即可。
