javascript - Form calculator using Each() and Children() in jQuery -

-

I am trying to create a form that calculates the total value based on string values ​​such as a series of drop down boxes It's like "this option costs £ 30" I know this is not ideal but IM is putting together an existing script as a hack

For most part Iive is working on it But I'm not sure that each function for each function How to not run child of #productconfig

I can input every drop down id manually into an array and it does the calculation, but it would be nice if it comes with all children of #productconfig Works

> pre & lt; & Lt; Div id = "# productconfig" & gt; & Lt; Label & gt; Model type & lt; / Labels & gt; & Lt; Select Name = "Product [220] [Data] [Model Type]" ID = "Data-Model-Type-220" & gt; & Lt; Option value = "M-type £ 500" & gt; M-Type £ 500 & lt; / Options & gt; & Lt; Option value = "P-type £ 500" & gt; P-Type £ 500 & lt; / Options & gt; & Lt; Option value = "S-type £ 500" & gt; S-Type £ 500 & lt; / Options & gt; & Lt; / Select & gt; & Lt; / Div & gt; & Lt; / Code & gt; & Lt; Code & gt; $ (Document) .ready (function () {$ ("# productconfig"). Children () .changes (function () {calculateoptions ();}); calculateoptions ();}); & Lt; / Code & gt; & Lt; Code & gt; Function calculation () {var arr = ["data-model type-20"]; Var Total = 0; JQuery.each (arr, function () {var str = $ ('#' + this) .attr ("value"); var poundsign = str.indexOf ('£'); var poundsign = poundsign + 1; var lengthofstr = Str.length; var shortstr = str.substr (poundsign, lengthofstr); total = eval (total) + eval (shortstr);}); $ ('# Value') Html ("£" + total); } & Lt; / Code & gt;

How about: 

  function calculations Options () {Var total = 0; Jquery ('# productconfig select') each (function () {total + = $ (this) .val (). Match (/ £ (\ d +) /) [1];}); $ ('# Value') Html ("£" + total); }

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
