Generate Timestamp To Avoid Duplicate Transactions?

Jan 19, 2010

Does anyone know of any "best practice" approach (or indeed ANY approach) to preventing accidental duplicate transactions on an e-commerce or online banking type site?

I'm having some issues on my site where the same transaction is being processed multiple times, and I've more-or-less ruled out user error (e.g. once the user clicks the SUBMIT button, some Javascript code disables it to prevent accidental extra clicks). It looks like the browser (or an intermediate proxy) is very occasionally reissuing GET and POST requests to the server, resulting in the same transaction being processed multiple times.

Ajax :: How To Display JPG File TimeStamp

May 12, 2010

I have a webcam that uploads an image to my non-profit's website via FTP every 15 seconds. The filename is webcam.jpg. I have a javascript that automatically reloads the image (NOT the entire page) every 15 seconds as well. The script is as follows:

<script type="text/javascript">
function reloadImage() {
var now = new Date();
if (document.images) {
document.images.myobject.src = 'images/webcam.jpg?' + now.getTime();
}setTimeout('reloadImage()',15000);
}setTimeout('reloadImage()',15000);
</script>

The script works great--the webcam image refreshes every 15 seconds without refreshing the entire page. What I'm trying to do is add javascript that will also display the timestamp of the webcam.jpg file when the image is refreshed (so that people know what time/date the image they're looking at was taken). I'm guessing this involves some sort of AJAX request, but I haven't the foggiest idea how to make it happen.

Can I Avoid Eval() Here?

Nov 23, 2006

I am trying to assign an "onclick" event to a dynamically-created DOM
element (an image).

I have read countless times that "eval()" is to be avoided at all costs.
However, I cannot seem to get my new onclick to work without it.

Here's what I have so far:

myeval = 'detachFile(this);'
detachImage = getElementById('detach-jfhahhf');
detachImage.onclick = function() { eval(myeval) }

This works perfectly fine for me, but this is a web-app that will be
exposed to public users, and I obviously don't want them being able to
eval anything if i can help it.

Can that be done without the eval()?

Avoid Enter Key In IE And Netscape

I wrote this function to avoid the enter key in some of my textboxes.
In IE the function works as expected, in Netscape 6 or 7 it does not
work. How can I make my function works in both IE and Netscape.

<input type="text" maxlength="13" id="txtType" onKeyPress="NoEnter();"
/>

<Script language='Javascript'>
function NoEnter()
{
if (window.event.keyCode == 13)
{
window.event.cancelBubble = true;
window.event.returnValue = false;
}
}
</Script>

Setting The Duplicate Cookies?

Jan 12, 2010

My text and what I have been researching on the internet has not been very helpful in determining the code that I need to prevent a user from entering his/her information more than once. Here is my current code

<!DOCTYPE HTML PUBLIC "-//W3C//DTD.HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/htm14/loose.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

[code]....

I have created a new web page to link the duplicate cookie too, titled doubleinfo.html. This is what I am using to let the user know that their information has already been entered.

My text is telling me that I need to look for a nextform() function, but I didn't have to write one so what would I need to do, if anything, to start the document.cookie = "name" codes?

Avoid A Circular Equation In Js?

Oct 22, 2010

Im working on a project for my website where I would like to be able to change the value of a number by using js, and using getElemenById. For example:

"The taxi fare is $25"
"A hamburger is $4"

In the above sentence I would like to be able to change the value of 25 & 4 by giving them an id and then using js to increase (or decrease) their value, to allow for future inflation, without having to go back and manually change every number on lots of pages (if for example in 1 years time a hamburger is worth $6 then the info above is outdated and should be changed). If i could use a variable such as "RateUSD = 1" I could increase "1" to say "1.05" and it would increase the value of all id='USD' by 5% onload rather than having to manually change it by typing.

I so far have come up with the code below, but I think the reason it does not work is because I have created a circular equation - id='USD" is the start of the equation, but it is also in the equation itself, and it is the resulting answer, so effectively I have created "A = A*B", or in this case "25 = 25*1.1"

I chose "id" as I would like to be able to have different currencies (with different id, such as 'EURO','GBP', etc) on the same pages and on multiple pages. I'll crack it eventually, I would just like to know if I'm heading in the right direction, or is there a better method that I could use? I found plenty of example for changing text with "innerHTML", but so far I haven't seen any for updating numbers onload by calculation, except for forms, etc, which are different.

The code:

<html>
<head>
<script type="text/javascript">
function changeCurrency(){

[Code].....

I will later put the js in an external file with a link to it "...src="support-files/currencyChange.js" (or something like that), but for now I have put it on the same page.

Duplicate Checking In An Array

Aug 3, 2006

I have a single dimension array with the following data stored on it.

a[0] = 1~1~10
a[1] = 1~2~11
a[2] = 1~3~15
a[3] = 1~4~19
a[5] = 1~6~10

Here in my case a[0] and a[5] is duplicate because i am using 1 or 0 for active and deactivate purpose a[4] is deactivate value so we can ignore the 10 in this. so in my case 10 is repeated twice on a[0]and a[5] not a[4], so its duplicate value. can any one help me to solve this.

Duplicate Variables Being Passed To GET

Nov 8, 2010

The problem I am having is when the following script is executed within my page and the user submits the form, the variables passed to the GET array are duplicated only for the inputs created by my script. I have other inputs in the form that are created within the HTML of the page that work fine (i.e. they only try to pass their value once) but I cannot get my script to work properly.

Here is my script:

Here is an example of what the url looks like after the form containing this script has been submitted:

The input (segments) created in my page only submits itself once, while anything created by the script (segment_type_1, segment_type_2, etc.) submits itself twice with the second, blank value overriding the first, correct value.

Duplicate Values In Drop Down List Box

Jul 20, 2005

Problem: I have two dropdown list boxes with same data(all data driven).
These are used for two separate entries. For every entry you cannot choose the same value twice. For example, I cannot choose for entry 1 the same value in both selection boxes (gqCategory1Entry1 and gqCategory2Entry1)

This part works.

The second entry is the problem: When I choose a value for Entry
Two that is the same as in entry one it thinks that "Dubplicate
Divisons have been selected").

WHen in fact these are two separate entries.
