i am new to J query , today is my second day. I am working on a code which i need to modify. Code is in ASP.net , J query and back end SQL server. Question is: how i check the value on a text box with database table.
I would like to use jQuery to prepopulate a form - ie make a call to a php program to get data from a database and pre-populatea form with appropriate data for the user. Can anyone point me in the right direction for some examples on the simplest way to do this?
I managed to send data from the form using php & jquery/ajax. But now I need to be able to load that data back onto the form. Is it somehow possible to use the code I have for sending the data to retrieve the data?
I'm triyng to use the $.ajax jquery function to insert some dates in a database, using php.I have the page that insert the data called : sign.php and in the page I have the form, and the ajax scritp.
if I use the page without ajax it works, if I use the script jquery it works but doesn't insert the dates in the field, it send only white field. can't pass the variable POST beetween the ajax script and the php script.
I am new to jquery and i have no freaking idea about jquery. One of the requirement is to use Jquery to datastore and dataretrieval so on my aspx page, a user enters a comment and clicks on "Add" button.When user clicks on Add button, I wan to add comments to database. Once data is added to db, I also want to retrieve same data, user name and current datetime as a dataset and show it on the page. How can I achieve this? I am creating a webservice which accepts "comments" as parameter and stores into database.
I have a .load that executes a php mysql query from another page. This query displays all the data of the database. Each result is wrapped around a div.
<div id ="post<? echo $row['post_id']; ?>">
the id of the div depends on the post id of the result. How do I put the data of $row['post_id'] in my javascript?
Few days ago since I started using JQuery amazing world, I got some basics to get started, I created a dialog in which I included a form that contains two text fields and a button to submit, what I want (in which I stuck now ^^) is the data interred within the form to be sent to the database, I used to do the following:
I have a simple AJAX chat room and it's taking too much local bandwidth when it downloads. What I want to do is call a page with AJAX that checks for new entries in the database and sends a response if there are new ones. But if there's nothing new it just doesn't respond. That way a user won't have to download a response with no new material. Is this okay to do? Am I correct in assuming this will have a positive affect on bandwidth?
I'm very new to jQuery, only picked it up yesterday, so there is very little I understand at the moment. I have a website on which I would like to display a real time, time-series chart displaying results from a database that is constantly updated. how to pull live data from my database and display it in an alert box on my sight. One of the replies said I should use jquery to achieve this.
I am looking for a solutions for the following problem, I need to access at database from within a website, from where I can retrive a specific document in the database and mailing it to someone else. Of course I cut crab the document from the database and save it on my harddrive, and then send it. But this process don't fit into our busy days.
im trying to get values from a database and assign them to icons which display on my page. The icons that are generated on the page are generated in javascript- and they do work. Howver i want icons to hold the names that are in the database/table.
how would i do this? would this be using a query result in asp to get the values from the database?? how would i do this? please provide code or guide.
then, how would i assign the database value with the icons???? ive heard javascript arrays??? how would i assign the values??
Im having the weirdest problems with my ajax. Now first off i have horrible coding convention!! I have one Ajax.js file which handles all my ajax requests and one ajax.php file which handles retrieving data from a database. The problem I am having is when ever I call a certain method which contains a if statement and runs the respective ajax function, it sometimes evaluates the if statement wrong. The weirdest thing of all is when I use FireFox's firebug and step through the javascript code to see why its evaluating the if statement wrong, it evaluates it correctly.
So basically if I don't step through the javascript code it evaluates the if statement wrong which means one of my variables are not being set in time for it to be used in the if statement. BUT if i step through the code with firebug it evaluates the if statement correctly! Now I have tried this is all the browsers and sometimes it evaluates the if statement correctly and when i keep refreshing the page it will sometimes evaluate the if statement correctly! Now I know this makes no sense, but I'm just as confused! The only reason I can think why this is happening is that one of my variables are not being set in time for the if statement to use it!!
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 want to build-up ajax based friends system. though i no nothing about ajax (would like to learn but) actually i have form where user can add his friend. on very next page of this page he/she can see what he/she is entered and where
they should probably see the add and remove button(which i want to build up using ajax)
how to start for this? till now i have code where user can write his friend name and to the next page he/she can see the value he has written. on submit button it all goes in to database. means i have devloped php form for this.
Not sure if this is the correct forum as it covers data retrieved from mysql in a .js file...
I need to grab the last 5 rows from my database (2 fields per row) and list all 5 in a table but from within a .js file that I can externally link to.
I can manage the php / mysql and the output to a .php page but how can this be contained within a .js file?
I believe it is possible but after 2 days of searching on google I'm appealing for assistance.
I realise this could be done with a php include or iframe but that isn't an option and the only way available to import this data is via an external javascript script.
I'm trying to pull data from multiple database tables and output them into a table which I've done fine, but I'm having trouble trying to filter the rows by specific values like colour and size selected from select boxes without reloading the page.
After more than a day of looking though I have made no progress, If this was to be done with just PHP and MySQL reloading the page I'd have no problem but having problems with the AJAX side.
