Chaining selects with Chosen -

-

i'm trying chain selects chosen , chained i'm not sure if i'm implementing .chosen().change() correctly or if error i'm getting bug.

here's i've got:

<select id="inputfield_date" name="date" data-placeholder="select event date"> <option value=""></option> <option value="wa">wa</option> <option value="qld">qld</option> <option value="vic">vic</option> <option value="nsw">nsw</option> <option value="sa">sa</option> </select>  <select id="inputfield_code" name="code" data-placeholder="response code"> <option value=""></option> <option value="601" class="wa">601</option> <option value="602" class="wa">602</option> <option value="402" class="qld">402</option> <option value="403" class="qld">403</option> <option value="301" class="vic">301</option> <option value="302" class="vic">302</option> <option value="201" class="nsw">201</option> <option value="203" class="nsw">203</option> <option value="501" class="sa">501</option> </select>  $('#inputfield_date').chosen().change(function() {     $("#inputfield_code").chained("#inputfield_date"); });

which gives me uncaught rangeerror: maximum call stack size exceeded.

edit: need hide/show field if particular option chosen , i'm not sure correct approach that.

using example chained documentation i've put example on jsfiddle.

and simple, initialize chained , chosen do, , trigger chosen:updated event if 1 of selects changes:

var selects = $('#inputfield_code, #inputfield_date'); $('#inputfield_code').chained('#inputfield_date'); selects.chosen({width: '300px'})  selects.on('change', function(){     selects.trigger('chosen:updated'); });

edit:

for second question i've updated fiddle bit: http://jsfiddle.net/koenpunt/fzh9g/2/

chosen sends option selected alongside change event, checking if specific option selected easy:

$('#series').on('change', function(event, data){     // first check if data exists, because if change event     // isn't triggered chosen `data` undefined     if(data){          if(data.selected == 'a5'){             $('#submit').hide();         }else{             $('#submit').show();         }     } });

as notice, if select 'audi' , 'a5' button disappear.

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...
