javascript - know the image user is viewing in slimbox2.js -

-

i have image gallery uses slimbox2.js

i want know image user viewing @ given time. how viewing image? (note user need not click on every single image view, once clicks single image , slideshow loads can use mouse clicks or arrow keys browse through images in gallery)

example: the user clicks on first image in gallery. can add click event listener , event, record user viewed first image. happens if user selects click next button in slimbox2 , view next image.

the user viewed second image don't know, user viewed it. how can capture event?

another approach thought of image slimbox2 loads it's view, there event triggered @ moment?

you can url of image using jquery..

jquery("#lbimage").css("background-image").tostring().replace('url(','').replace(")","")

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
