Preventing Firefox reload confirmation
提问by Emmi
I'm displaying certain records in an editable table. The user when attempts to reload the table while editing a record a pop up comes warning the record about the unsaved data.
我在可编辑的表格中显示某些记录。用户在编辑记录时尝试重新加载表时，会弹出一个警告记录有关未保存数据的记录。
function cancelProcess()
{
if(noEditedRecords !=0)//number of edited records in the table
{
var processConfirmation = confirm("You've Edited "+ noEditedRecords +" Records. Are You sure to undo the Changes made?");
if (processConfirmation ==true){
window.onbeforeunload = null;
window.location.reload();
}
}
}
When he clicks OK to reload the page, Firefox prompts as
当他点击 OK 重新加载页面时，Firefox 提示为
To display this page, Firefox must send information that will repeat any action (such as a search or order confirmation) that was performed earlier.
要显示此页面，Firefox 必须发送信息来重复之前执行的任何操作（例如搜索或订单确认）。
And when opening the same page in Chrome, no such prompt appears.
而在 Chrome 中打开同一个页面时，也不会出现这样的提示。
I tried to avoid this by setting window.onbeforeunload = null;, but still the prompt window appears there.
我试图通过设置来避免这种情况window.onbeforeunload = null;，但提示窗口仍然出现在那里。
Also I tried by changing Firefox configuration:
我也尝试通过更改 Firefox 配置：
browser.sessionstore.postdata
browser.sessionstore.postdata
Changed 0 to 1as suggested in Mozilla support page.
按照 Mozilla 支持页面中的建议将 0 更改为 1。
But nothing worked.. How do I prevent the prompt?

The behavior is correct. According to w3schools reload has a parameter forceGetthat is default false, and as a result if you have a POST submit, the the browser will try to resend that POST data, and as such, it needs your confirmation. Firefox does this right, and google chrome behaves like it has a default of true for forceGet
行为是正确的。根据 w3schools reload 有一个参数forceGet，默认为 false，因此如果您有 POST 提交，浏览器将尝试重新发送该 POST 数据，因此，它需要您的确认。Firefox 这样做是正确的，而 google chrome 的行为就像它的forceGet的默认值为 true

while window.location=window.locationor window.location=window.location.href(or any other variation of this) works most of the time, when you are using an anchor url like http://www.google.com#testwill not be refreshed with this method. The browser will do the exact same thing as it will do when you are already on google.com and you change the url by adding #test. The browser will just try to locate the anchor tag in the page that has the name test, and scroll down to it, without refreshing your browser.
而window.location=window.location或window.location=window.location.href（或此的任何其他变体）大部分时间都有效，当您使用像http://www.google.com#test这样的锚点 url 时，此方法不会刷新。当您已经在 google.com 上并通过添加 #test 更改 url 时，浏览器将执行完全相同的操作。浏览器只会尝试在具有名称 test 的页面中找到锚标记，然后向下滚动到它，而不会刷新浏览器。
The solution that works in this case as well as any other case I encountered would be window.location.reload(true);
在这种情况下以及我遇到的任何其他情况下都有效的解决方案是 window.location.reload(true);
Hope this helps,

The way to avoid that prompt is to not create a situation where a user is trying to reload a POST result page.
避免该提示的方法是不要造成用户尝试重新加载 POST 结果页面的情况。
