html - how to check the div value in javascript -

-

how set div css styles using javascript? have problem getting value of class name. please if know it.

<div class="this_is_i_want_to_set_the_background_color" id="divname"></div> <div class="test" id="divname"></div>  var classname = $('.divname').attr('class'); var t = 'divalue'; if(classname == t){     $('.divname').css('background', '#0962ae'); }

you may use .hasclass method:

$('.divname').each(function() {     if ($(this).hasclass('divalue')) {         $(this).css('background', '#0962ae');     } });

but there 1 simpler way this:

// element class 'divname' has class 'divalue' $('.divname.divalue').css('background', '#0962ae');

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (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...
