Real Time Update Total Count Results Number

Jun 8, 2011

How to get a number to update realtime on a site? What I'm looking for is used on the following website:
New & Used Cars For Sale - Arnold Clark
The number with the top vehicle search update when a user makes any of the selections in the form. I think I know how to get the number to update via php and mysql queries on the db but how can I get the effect where the number rolls to the newly updated total?

How Can I Count The Total Number Of Results Displayed?

Dec 2, 2002

I'm currently working on a javascript form validator and have run into a problem. The validator is used to make sure that the customer has entered a number in the quantity input box of the item they wish to purchase.

Code:

function validateRE(fieldToCheck, strRegExp, msg, min, max) {
if (!min) { min = 0 }
if (!max) { max = 100 }

for (i=0;i<15;i++)
{
if (fieldToCheck[i].value) {
var re_pattern = strRegExp;
if (!re_pattern.test(fieldToCheck[i].value) || fieldToCheck[i].value.length < min || fieldToCheck[i].value.length > max) {
alert(msg);
fieldToCheck[i].focus();
fieldToCheck[i].select();
return false;
}
}
}
return true;
}
Used with:

Code:
<form method="post" action="../some_URL"
onsubmit="return (

validateRE(this.quantity, /^[1-9]{1}$|^[0-9]{2,3}$/,
'Please enter a Quantity.', 1, 3)

);">
The part in question is the red highlighted section.
The number of items that is under a specific product is generated dynamically and can range from 2-20. How can I get javascript to count the total number of items and run "for i=0;i<total number" instead so it is different for each product page?

I do have the countdown script (see link below) to display the time between current time and the date given in real-time. However, I want to achieve to display the time difference between a given start and end time. Right now, it calculates from the current server time to the end time. I want to be able to set up my own start time and end time.

How Can I Update A Form In Real-time?

Jan 31, 2007

I'm making a survey where every question has a numeric value assigned to it, and as the user clicks on a checkmark button to approve (or uncheck to disapprove) the values add or subtract to give a total at the bottom of the page.

Basically, it's a spreadsheet but with fixed values for each row instead of being able to type them in.

I can do this easily with php, but only if the user clicks the submit button. I was hoping to find a way to do this real-time.

I'm not looking for someone to do this for me, but can someone point me in the right direction of a tutorial or something that is similar so I can build this into my program?

Adding Multiple Input Boxes And Getting A Total Different Number Every Time?

May 19, 2011

ave this form which gets created by pulling stock/products from a database using PHP and beside every product in the row is a little box for input and in there the user can input the quantity of the product they want. Sometimes only 2 products will be outputted and other times 10 or more.What I want to happen is when the user enters in lets say 3 for the quantity of a certain product I want to get a total for how much 3 of that product will cost so I just do 3 multiply by the cost (which I have from the database) and then display the total cost down under where the list of the available products are and I want all this to happen dynamically obviously not using PHP because I don't want the page to have to reload every time they enter in a new quantity.

I know how to display text and stuff in certain divs with certain ID's using Javascript but I just don't know how to keep track of a form and do what I want to do when the number of inputs in the form can range from 1 to 10 or more. Im thinking of some sort of counter which gives every input a different ID like add 1 at the end of the ID name of the input as the PHP script loops through the database query displaying the products but I still don't know how to go about the Javascript side of things

Convert Time String To Real Time Value

Mar 4, 2009

I need to convert a string containing the time to a real time value so I can insert it in to a time column in my database. tempElapsed = "1:22:33:44:555"

var _tempElapsedHours = tempElapsed.substring(2,4);
var _tempElapsedMinutes = tempElapsed.substring(5,7);
var _tempElapsedSeconds = tempElapsed.substring(8,10);
var _elapsed = Date.parse(new Date(_tempElapsedHours,_tempElapsedMinutes,_tempElapsedSeconds));

The result of elapsed is -1.4243e+012, I was hoping for a time value of 22:33:44

JQuery :: Countdown Real-time Updates

Sep 21, 2010

I have been using the jquery countdown plugin made by [url] for a while and while I am pretty familiar with it, I haven't been able to accomplish what I want for one of my projects.

I want to be able to add hours/minutes/seconds to a countdown in real-time by clicking a button.

Let's say I have 2 countdowns. They both get their ending date from a mysql db, e.g: 2010-09-26 00:00:45 and 2010-09-27 14:45:00

When I click a button, I want the countdown Y to increase by the X amount of hr/min/sec, update my ending date in mysql, and update my counter for every visitors to see without having them refresh the page. I have tried messing with ajax, but wasn't able to accomplish anything close. (I got it to update every 1 sec but it would flicker then)

Changing Element Styles In Real Time

Feb 6, 2003

I'm using sliders to change text colour dynamically; at the moment, I'm doing it by iterating through the getElementsByTagName collection; like

paraAry = document.getElementsByTagName("p");
paraLen=paraAry.length;
for(j=0;j<paraLen;j++){
paraAry[j].style.color = "rgb("+bodyColor[0]+","+bodyColor[1]+","+bodyColor[2]+")";
paraAry[j].style.borderColor = "rgb("+textColor[0]+","+textColor[1]+","+textColor[2]+")";
paraAry[j].style.backgroundColor = "rgb("+textColor[0]+","+textColor[1]+","+textColor[2]+")";
}

But blatantly it's well inefficient; is there a better way to achieve this - like just a single property I can change to make all elements of a given name change.

Save Real-time Data In Client PC?

Oct 9, 2009

I am using Ajax and Javascript to show real-time data on the web page. On my web page, a 4-digit number is displayed in a text box and this number updates every 10 millisecond automatically to display real-time data (show 100 numbers per second).

What I would like to do is to save the lastest 10 second data in the local PC (client PC) when client clicks a button on the page. Is that possbile with Javascript and Ajax? Or is there any other ways to sort it out?

Just gathering general idea here...

let's say I have a table "Names" with a field "name" --> bob, and tom (2 records)

I want the ajax/php page to pull out all the names. which would be bob and tom. And then if my database got updated at the backend (ex: a new name jack is added). my page showing bob and tom will automatically be updated with jack showing.
