Microsoft Edge adds parameters after navigating to a route on angular 2

Question

I have a form being filled in two steps, the first form fills in the main part of an object and the second, the sub-part. There is a method that navigates back from form2 to

Answer 1

To fix this problem, add type="button" to the button tag. Edge is apparently assuming that any button without an explicit type is type="submit", for which it is posting the values in the form.

I had explicitly included the form tag in my page so that I could access the form properties in the .ts code. I removed that form tag and associated code, and the navigation works in Edge. So Edge seems to be assuming that my button was a submit button. After including type="button" in the button attributes, I was able to put the form tag back in, and it all still worked.
