javascript - JQuery: Event handlers stop working when window is resized -

-

jsfiddle link: http://jsfiddle.net/4qldc/6

this js code:

var togglecontent = function (event) {     $(event.target).siblings().toggle(); }; var showorhidepanels = function () {     var windowheight = $(window).height();     var windowwidth = $(window).width();     if (windowwidth < 980) {         $(".headbar1").siblings().hide();         $(".headbar1").parent().css("min-height", 0);         $(".headbar1").css("cursor", "pointer");         $(".headbar1").on("click", togglecontent);     }     else {         $(".headbar1").siblings().show();         $(".headbar1").parent().removeattr("style");         $(".headbar1").css("cursor", "auto");         $(".headbar1").off("click", togglecontent);     } }; $(function () {     showorhidepanels(); }); $(window).resize(function () {     showorhidepanels(); });

this trying achieve.

when window width less 300px:

  1. the content box should collapse
  2. the headings should become links
  3. when heading clicked, content box should toggle

the first 2 happening, third 1 having trouble with. of time works , of time doesn't (the behaviour unpredictable; in jsfiddle page if try resizing "result" frame 6-7 times, work fine first 6 times fail seventh time). doing wrong? how fix this?

var togglecontent = function (event) {     $(event.target).siblings().toggle(); }; var showorhidepanels = function () {     var windowheight = $(window).height();     var windowwidth = $(window).width();     $(".headbar1").off("click");     if (windowwidth < 300) {         $(".headbar1").siblings().hide();         $(".headbar1").parent().css("min-height", 0);         $(".headbar1").css("cursor", "pointer");                 $(".headbar1").on("click", togglecontent);     }     else {                 $(".headbar1").siblings().show();         $(".headbar1").parent().removeattr("style");         $(".headbar1").css("cursor", "auto");            } }; $(function () {     showorhidepanels(); }); $(window).resize(function () {     showorhidepanels(); });

is wanted ?

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
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...
