Find The Balance Between Javascript (jQuery) And Code Behind

Jun 3, 2010

How do you currently find the balance between javascript and code behind. I have recently come across some extremely bad (in my eyes) legacy code that lends itself to chaos (someHugeJavafile.js) which contains a lot of the logic used in many of the pages.

Let's say for example that you have a Form that you need to complete.
1. Personal Details
2. Address Information
3. Little bit more about yourself

You don't want to overload the person with all the fields at once, so you decide to split it up into steps.

Do you create separate pages for Personal Details, Address Information and a Little bit more about yourself.
Do you create controls for each and hide and show them on a postback or using some update panel?
Do you use jQuery and do some checking to ensure that the person has completed the required fields for the step and show the new "section" by using .show()?

Javascript - Jquery Postal Code Clientvalidate?

Jan 20, 2011

I am working on a customvalidator to validate and replace (if possible) a postal code.

This is a Dutch postal code and should look like "5050 AA". When the user enters "5050AA" this postal code should be replaced with "5050 AA". I tried this by adding the following script to my page, which is called in the customvalidator:

<script type="text/javascript">
function Postcode_ClientValidate(source, arguments) {
var val = arguments.Value
var result = "";
var myPCRegExp1 = new RegExp("^[1-9][0-9]{3}s?[a-zA-Z]{2}$", "i");

[code]....

However, the script above is picking up the "5038AA" but not the "5038 AA" as a match, so i can't validate a working postal code and can't rewrite to the valid postal code.

Jquery - Calling Javascript From Code-behind Using Ajax?

Feb 16, 2011

So I have this idea of creating a asp.net user control, to handle all forms of modal popups (whether it be error handling, forms, dialogs, etc).

I already created this before, placing the user control in the top master page, exposing it to all content pages, so I could do something like:

Master.Popup.ShowException(Exception);

And the usercontrol itself would have the necessary markup to look like a modal dialog, and in the show method just do a .Visible = true.

This is all fine, but I've started thinking of implementing a bit of style with jquery. I'd like for the usercontrol to have some sort of jquery animation on show. But I don't know how to go about achieving this, as I don't know how I would call that jquery function from the codebehind instead of the popup.visible = true.

I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).

var _countDowncontainer = 0;
var _currentSeconds = 0;
function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID);

Jquery - Click On Table Row To Fire Both JavaScript And C# Server Side Code

Feb 16, 2011

I have a pop-up div contains a table.

I need to make table rows clickable and can be catched by both js and .net server side .

how can I use Request.form to solve this issue? since I've created functions for js part .

The reason why I want to fire sever side event, because I use JS to add option (item) to an asp:ddl in an updatepanel, it will cause error or lose the new option by doing a postback fired by other buttons.

So I could find all input elements that will require validation.And use this in a loop to add validation to the input's found :

$('input').attr("customAttribute").val() == "validateMe"

I could also write every validation for each object separately, I have only a few elements who uses a required validation but it would be nice that I could do this in one shot instead of repeating the $("input").rules("add .....

SQL Server :: Query For Available & Ledger Balance

Aug 12, 2010

I have a web page that allows user to make transaction and they are allowed to choose if they want their transaction to be immediately transferred to the payee or for future transfer. I have problem handling future transfer, for an example, I want to transfer $100 to A on 12 August but today is only 09 August. So the amount should be deducted . I decided to make 2 balances; Available and Ledger balances. Available balance is the net balance after doing all the future transfers etc. but for ledger balance is what is available at the point of time. I'm thinking how should I form the query for the SQL statement. Currently, this is what I have. Transfer code = 2 -> future transfer

IF (@TransferCode = '2')
BEGIN
--Insert into the account transaction table first--
INSERT INTO ACCOUNTTRANSACTIONS (AccountTransID, CustID, TransDate, TransType, Reference)
VALUES (@AccTransID,@CustID,@Date,@TransType,@Reference)
IF NOT (@Date = Getdate())
IF (@Withdraw > @BankBal)
BEGIN
INSERT INTO ACCOUNTTRANSITEM (AccountTransItemID, AccountTransID, AccNum, Withdraw, Deposit, status)
VALUES (@AccTransItemID, @AccTransID, @AccNum,@Withdraw,@Deposit, 0)
PRINT 'INSUFFICIENT AMOUNT IN BANK'
SET @ReturnValue = 4
RETURN @ReturnValue
END
ELSE
BEGIN
INSERT INTO ACCOUNTTRANSITEM (AccountTransItemID, AccountTransID, AccNum, Withdraw, Deposit, status)
VALUES (@AccTransItemID, @AccTransID, @AccNum,@Withdraw,@Deposit, 1)
END
ELSE IF (@Date = GETDATE())
BEGIN
IF (@Withdraw > @BankBal)
BEGIN
INSERT INTO ACCOUNTTRANSITEM (AccountTransItemID, AccountTransID, AccNum, Withdraw, Deposit, status)
VALUES (@AccTransItemID, @AccTransID, @AccNum,@Withdraw,@Deposit, 0)
PRINT 'INSUFFICIENT AMOUNT IN BANK'
SET @ReturnValue = 4
RETURN @ReturnValue
