I am trying implement query strings to work with pyjamas so that users can
jump directly to sections of a program using hyperlinking and so I can
create a sitemap. For example when a user
types http://localhost:8000/#page_get?name=technology;level=0 in the
browser, it will take them to a specific page. The program already uses
history tokens (support for backwards and forwards). My assumption was to
use History.getToken() and History.newItem() for reading/creating query
strings. Is this what GWT people use for hyperlinking their programs?
The problem is the error pyjs creates from calling history.html (code
listed below). There is nothing in my program that calls history.html, so
it must be a behind the scenes, pyjs black magic, required to get History
working. Since there is no history.html handling on the server side I get
an error. I posted my errors below. Can someone with a some knowledge with
history/querystrings give me a rough explanation on what is happening and
guidance on how I should be creating query strings?
I am a hobbiest programmer, so please excuses any wrong nomenclature above.
