javascript - Implementing Column resize using jQuery -

-

i trying implement column resizing using jquery below(please see http://jsbin.com/udunubo/1/edit)

here js code 

     function resizeevents(selector) {         function xy(e, ele) {             var parentoffset = ele.parent().offset();             return e.pagex - parentoffset.left;         }         var checkpos;         $(selector).on('mousedown', function () {             $(this).attr('init', true);             return false;         });         $(selector).on('mouseup', function () {             $(this).attr('init', false);         });         $(selector).closest('div').on('mousemove', function (e) {             var inits = $(this).find('.resize').filter(function(){                 return $(this).attr('init') == true;              });             if (inits.length > 0) {                 var pos = xy(e, inits.first());                 if (!checkpos) {                     checkpos = pos;                     return false;                 } else {                     var moved = checkpos - pos, = moved > 0 ? 1 : -1 ;                     th.prevall().each(function () {                         if (!$(this).hasclass('.resize')) {                             $(this).width($(this).width() + a);                         }                     });                     th.nextall().each(function () {                         if (!$(this).hasclass('.resize')) {                             $(this).width($(this).width() - a);                         }                     });                 }             }         });     }      resizeevents('.resize');

but not working, question is mousemove written properly, define on correct element or not.

i fixed code you:

function resizeevents(selector) {   var selected;   $(selector).on('mousedown', function () {     selected = $(this);     return false;   });   $(document).mouseup(function () {     selected = null;   }).mousemove(function(e) {     var target = $(e.target);     var table = target.parents('.table');     if (table.length && selected) {       var x = e.pagex - table.offset().left;       var splitter_x = selected.offset().left;       var prev = selected.prev();       var next = selected.next();        prev.width(prev.width() + (x - splitter_x));       next.width(next.width() - (x - splitter_x));     }   }); }

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...
