php - javascript sum returning NaN error -

-

i have javascript shopping basket, in sum returning nan error,almost every time. in code have 

    $('#add-to-basket select').selectbox();     $('#contents select').selectbox().change(function (e) {         var product = $(this).parents('.product');         var ppu     = product.find('.ppu').val();         product.find('.price .wrapper .value').text($(this).val() * ppu);          var total   = 0;          $('.product .price .value').each(function (index, value) {             total += new number($(value));         });          var form = $(this).parents('form');         form.ajaxsubmit(function () {         });          $('#total .value').text(total);     });

i tried using parsefloatm still dosn't work...

$(value) gives jquery-wrapped element, not actual value.

you want $(value).val() instead if elements form inputs, or $(value).text() if not.

also, instead of new number(...) should use number(...), or +...:

$('.product .price .value').each(function (index, value) {     total += +$(value).val(); });

see this question difference between new number , number.

magically formatted comments change reported line number of javascript errors in browsers; this: //@line n "f" n line number , f file name. unfortunately, //@line appears ungoogleable. know there documentation on feature, , browsers support it?

c# - Is it possible to remove an existing registration from Autofac container builder? -

something along lines: builder.registertype<mytype>().as<itype>(); builder.registertype<mytype2>().as<itype>(); builder.deregistertype<mytype>().as<itype>() var container = builder.build(); var types = container.resolve<ienumerable<itype>>(); assert.istrue(types.count == 1); assert.istrue(types[0].gettype == typeof(mytype2)); scenario: go through bunch of assemblies , go register types want make sure have 1 implementation of given type. need before create container. track on own nice if autofac me bit. this cannot done directly using containerbuilder , unless start on new one. mind you, having first built container should able construct new container filtering away unwanted types , reusing registrations first container. this: ... var container = builder.build(); builder = new containerbuilder(); var components = container.componentregistry.registrations .where(cr => cr.activator.limittype != typ...

php - Mysql PK and FK char(36) vs int(10) -

-
i have read mysql can handle indexes , searches better if tables keys integers rather char(36) uuid's. is worth converting int(10)? note: use 1 server , have have plans use multiple databases concurrently therefore removing 1 of big reasons using uuid. our tables innodb if makes difference. thanks in advance. usually rdbms can handle integer keys pk more efficient, other datatypes. reason how build index column, yes: long dont require string (or other typed) keys, should use integers. however: char(36) , int(10) far away being equal, because int(10) much smaller, char(36). dont know, if require many different keys, should keep in mind. update, complete last paragraph: int(10) 32-bit, char(36) 36 - ^byte^ (= 288-bit). not mean, int consumes less space, means, char(36) has 4 times more different keys.
