jQuery：如何知道页面是否已刷新

Question

I would like to know if it is possible to check if a certain page has been refreshed after clicking browser reload button or F5 and create a specific function.

For example:

if(page has been refreshed) {
 code
} else {
 other code
}

Answer 1

when a page is refreshed, the page and all js variables will be restored to its original state. You might be able to do it if you set a flag in the browser's cookies or localstorage, so when the user refresh the page, you can check if the flag was set.
