javascript - Ajax request extremely slow -

-

i don't know why, javascript extremely slow , takes 5 minutes finish properly, refresh pages , requests haven't been processed.

i used async:true hoping process little bit faster doesn't. here's code using save each element on inside #myspace.

cn = document.getelementbyid("myspace").childnodes;         (var t = 0; t < cn.length; t++) {             if (cn[t].nodetype == 1) {                 var n = {                     id: cn[t].id,                     left: cn[t].style.left,                     top: cn[t].style.top                 };                 $.ajax({                     data: n,                     url: "/application/ajax/__ajaxprofile.php?a=saveposition",                     type: "post",                     cache: true,                     async: true,                     success: function (e) {}                 })             }         }         e("please wait save, might take more minute.");          setinterval(function () {          if ($.active == 0) {              $('#close-modal').show();          }          }, 10);

anyone knows why it's been processed , decent solution this?

var n_array=new array();  (var t = 0; t < cn.length; t++) {     if (cn[t].nodetype == 1) {         var n = {             id: cn[t].id,             left: cn[t].style.left,             top: cn[t].style.top          };          n_array.push(n);           } }  $.ajax({    data: n_array,    url: "/application/ajax/__ajaxprofile.php?a=saveposition",    type: "post",    cache: true,    success: function (e) {} })

should way faster, , produce less traffic. ofc you'll have change processing code little...

-
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...
