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?
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.

<option value="11">11 Months</option>
<option value="12">12 Months</option>
</select></li>
<div class="grand_total">
<h4 class="colr">Price</h4>
<ul>
<li class="price">$0.50</li>
</ul></div>
1 Month and 1 User price should be 0.50 USD
+1 Month = + 0.50 USD
+ 1 User = + 0.50 USD
Example: 5 Users + 2 Months = 3.50 USD
I wanna make the jquery to show the total price at li class="price".
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?
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
I am making making class project and faced with some problems. I have found script (here) and learned.
1. not updating row number and row ID after deleting rows
2. not updating total sum if user change quantity
3. not updating grand total after deleting and changing quantity

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
How can i insert only a real number (an integer with only one decimal separator) in a edit field
perhaps in onchange event I have to test if the decimal separator in the text is > 0 I simply have to put it as a null key.
i am developing a help desk software using php and oracle, when an expert posts a solution to the user who asked it, an alert should pop up at the user's machine to alert them that a solution has been sent end then it should dissappear,i was told to use ajax to check real time and then use javascript to pop an alert but i didnt understand and was told to post it on the javascript section.

Is there anyone who can advise me on what I am doing wrong?

You can change to values of the "top" and "left" style attributes to position the clock anywhere on your page.

example,
say I enter a number in a text field,

how would I then be able to get the total in another test field, like:

I have a form that is using HTML and PHP to make calculations for an

other fields in this form.
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)
I need to make a counter that counts up (preferably in real time but not crucial).
Ideally, it would count up by 9 dollars per second and go to the hundred millions.
im currently trying to create a real-time username checker. Once the user enters the username I would like some javascript to run and check whether the username is already in the database, then if it is return 'this is already in use'.Unfortunately I am not able to use ajax.
View 9 Replies View RelatedI'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.
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.
I am wanting to write some programs that connect in real time with a server. The problem is I do not have a server and really do not know a whole lot about servers. I do know the basics, it connects with sockets and uses a unique port but I do not know how to build one, So I turn here.
Is it possible to make a server using javascript? If not, then what language is used for servers? is it possible for JS to connect to a foriegn language server?
Anyone know where some good tuts are on this? I type in javascript server in yahoo and just get info on JSP and SSI's..
