jquery - Capturing counter value in Javascript closure -

-

this question has answer here:

the following code creates 10 elements under <body id="container" />. when click on element, see alert value 10.

how can each alert show index of each element?

for (var = 0; < 10; ++i) {   var id = "#element_" + i;   $("#container").append('<p id="element_' + + '">foo</p>');   $(id).click(function (e) {     alert(i);   }); }

need create private closure

for (var = 0; < 10; ++i) {     (function(idx){         var id = "#element_" + idx;         $("#container").append('<p id="element_' + idx + '">foo</p>');         $(id).click(function (e) {             alert(idx);         });     })(i) }

(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...
