javascript - remove dash in phone number within razor -

-

i need call javascript method , using razor print parameters...

getnumber(@html.displayfor(model => model.phone1)">

however, javascript treats dash in phone number subtraction operator.

i tried regular expression remove dash, can't figure out right syntax. still performs subtraction operation , gives me javascript error [subtration result].replace not function 

getnumber((@html.displayfor(model => model.phone1)).replace(/[^0-9.]/g, ''))">

you should treat phone numbers strings, make sure javascript knows number string enclosing in quotes:

getnumber('@html.displayfor(model => model.phone1')

this should rendered this:

getnumber('1-800-call-me')

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/...
