javascript - Appending to current route in Backbone/Marionette? -

-

i have part of marionette app opening bootstrap modal. when happens, want register opening "navigate" event, using app.navigate("/modal",false); change url. in modal view listening history event close modal (useful android / mobile), append "/modal" current route, instead of root.

how can current route/url append "/modal" , call .navigate() function on?

thanks!

edit:

apparently phrase looking here, in terms of web development, "micro-state", explained @ blog here: http://chrisawren.com/posts/implementing-microstates-in-backbone-js

the approach suggested bypass backbone history altogether , directly interface html5 history stack, places need fullscreen modal don't want invoke router handling or change url, still want support button.

simply

router.navigate(router.fragment + "/modal")

i have data grid rows represent theta (0, pi) , columns represent phi (0, 2*pi) , f(theta,phi) density of dark matter @ location. wanted calculate power spectrum , have decided use healpy. what can not understand how format data healpy use. if provide code (in python obvious reasons) or point me tutorial, great! have tried hand @ doing following code: #grid dimensions nrows*ncols (subject change) theta = np.linspace(0, np.pi, num=grid.shape[0])[:, none] phi = np.linspace(0, 2*np.pi, num=grid.shape[1]) nside = 512 print "pixel area: %.2f square degrees" % hp.nside2pixarea(nside, degrees=true) pix = hp.ang2pix(nside, theta, phi) healpix_map = np.zeros(hp.nside2npix(nside), dtype=np.double) healpix_map[pix] = grid but, when try execute code power spectrum. specifically, : cl = hp.anafast(healpix_map[pix], lmax=1024) i error: typeerror: bad number of pixels if point me tutorial or edit code great. more specifications: data in 2d np array , can change numrows/...
