Ajax Timers - Refresh The Data Every 5 Second To Provide Slick Real Time Availability Info
Aug 17, 2009
I have a small app, my first real ajax project, which gives you details for product availability, for each day. The user selects a day (from a calendar) and then a time slot within the day. The app then displays how many slots are available for purchase, on that day, for that time... I wanted to refresh the data, every 5s, to provide slick real time availability info... but alas, when you change day (look at another day and time), the old timer still runs with the old arguments, and so it keeps resetting the 'details' panel to the previous day's details... how do I reset the timer? or delete the old one?
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 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.
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
I'm using the Timers plugin to do a count down timer.I would like to enhance my UI by having the numbering being counted down transition from black to red as it gets closer to 0.The jQuery UI demo for animate seems to be what I need, but what I'm having trouble figuring out is how to have it transition gracefully over time. It seems like the animation is a one-shot deal.
I am not sure, if this works. I make a function call with the ajax option of jquery.If I try this, the whole response data is shown in the specific #div.Is there any possibility to load only the content of "#div" from some.php?
I am attempting to create a profile page with PHP utilizing AJAX technologies as well. I need profile data to auto-refresh on the page when a change is made in the database but every 15-30 seconds intervals are fine too. I would really like to use AJAX/PHP for this because I think it will be good for me to know and learn.
I have checked the internet for this and all of the examples show a form select/combobox where you select a "User" and then it populates the information automatically in a div below.
But... I need AJAX or PHP to READ THE VARIABLE FROM THE URL instead of a form(Combobox) and ultimately refresh the data on the page with the results from the DB query in the php file.
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?
I have a form that is using HTML and PHP to make calculations for an order form. One of the fields is asking for a total number of workstations. I would like this field to be a real-time total of five 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 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.
F.e I have div which id is someDiv and input text which id is someInput - and how to do that value of input object will display in DIV in real time? If i type letter "a" in input, it should automatically display in DIV. Which function should I use?
What I'm trying to do is, a jquery script to show in real time the total price. I got this: <li>Users</li> <li> <select name="users" id="users"> <option value='1'>1</option> <option value='2'>2</option> <option value='3'>3</option> <option value='4'>4</option> <option value='5'>5</option> <option value='6'>6</option> <option value='7'>7</option> <option value='8'>8</option> <option value='9'>9</option> <option value='10'>10</option> </select> </li>
