Back Button For Chrome Full Blocking Feature

Anyhow, this can be done (detecting back button) with window.performance window.performance.navigation.type 2.

I dont accept that having to disable the button means youre doing something wrong and in fact developers in different facets have long run into this problem.

You can add a shim though, but youd have to change a little bit your code.

I looked it up and I can get older FF and IE working with this model.

Dont forget to add a default hash before register the event.

Testing for a nonexistent property like this window.history.madeupproperty results false.

So I was guessing if(window.history.pushState) might do.

Couldnt get my hands on an IE9 ( caniuse.comfeathistory ) for proper testing.

Back Button For Chrome Full Blocking Feature

To achieve the full blocking feature, I added the last line window.history.pushState(forward, null,.forward) after alert(.) row.

This did the trick.

I would look for an alternative method like setting a session variable or a cookie that stores whether the form has already been submitted.

This is because the back button is a workaround for the impracticality of the web before ajax.

It would prevent them from navigating in the way that they originally came as well.
