events - Extjs 4.2 Parameter in listeners function -

-

i've got problem controller

ext.define('app.controller.mycontroller', {     init: function() {         this.control({             '#myinputfield': {                 change: this.textfieldchange(parameter)             }         })     },     textfieldchange: function(parameter) {       //do     } });

its problem when give parameter here

change: this.textfieldchange(parameter)

then fire after site load , don't know why.

without parameter waiting change event should can any1 me please ?

it because:

change: this.textfieldchange here giving reference function property

change: this.textfieldchange(parameter) here giving result of function property (which if don't use return, undefined).

you can use eopts variable in function definition, custom parameter sending, see in example:

ext.define('app.controller.mycontroller', {     init: function() {         this.control({             '#myinputfield': {                 change: {                     fn : this.textfieldchange,                     params : {                         param1: 'something'                     }                 }             }         })     },     textfieldchange: function(textfield, newvalue, oldvalue, eopts) {         var params = eopts.params;         console.log(params.param1);       //do     } });

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...
