Many people will encounter this dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Js listens for browser fallback events

The code is as follows:

$(document) .ready (function (e) {

Varcounter=0

If (window.history&&window.history.pushState) {

_ window.onpopstate=function () {

Window.history.pushState ('forward',null,'#')

Window.history.forward (1)

Alert ("non-fallback")

}

}

Window.history.pushState ('forward',null,'#'); / / these two lines are required in IE

Window.history.forward (1)

})

Js fallback operation

If a fallback operation is performed in the browser, the page will be triggered to pop up a "non-fallback" pop-up box, where you can do the different processing you need.

Recently, we are implementing a requirement to listen to the return operation of the browser. This method is always used after Baidu, and the principle is as follows:

$(function () {)

PushHistory ()

Window.addEventListener ("popstate", function (e) {

Alert ("listen for the return button event")

/ / implement your own functions according to your own needs

/ / _ window.location.href=' https://www.baidu.com'

}, false)

FunctionpushHistory () {

Varstate= {

Title: "title"

Url: "#"

}

Window.history.pushState (state, "title", "#")

}

})
