javascript - IFrame get parameters from parent url on different domain -

-

it seems not possible default because error blocked frame origin x accessing frame origin y. know because of security allow partners integrate iframe. iframe on domain mysubdomain.mysite.com , contains search box. once user has made search has been redirected page partners-domain-containing-search-results.com search results on domain mysubdomain.mysite.com , read parameters url (hash , query string parameters) can't because can't read parent url parameters (from partners-domain-containing-search-results.com ).

you should able use top.location subdomain.mysite.com read parent urls of partners-domain-containing-search-results.com:

e.g. iframe hosted on mysubdomain.mysite.com , embedded in partners-domain-containing-search-results.com?hello=true#blabla should able run:

top.location.hash >"#blabla" top.location.search >"?hello=true"

note: cannot modify other domain's location object or see:

uncaught securityerror: blocked frame origin "http://domain2.com" accessing frame origin "http://domain.com". protocols, domains, , ports must match.

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
