could someone please point me in the right direction for creating an AJAX page that displays "live" data from a mysql database? I need the page to update its self every time data changes in a mysql table.
I am currently trying to create a live search box that as I type it will start displaying results that match.but it retrieves its data from an XML file, I need mine to retrieve from a column called FirstName within a table of an Access database.
How would I go about outputting something when a database value is being changed?
e.g. If im typing in a text field, which is saving what ive typed every time i keyup into a database field, it then shows on another page on another user computer as "User is typing something in field X"?
If no typing is happened, i.e. the database field value is not changing, nothing is echoed out.
It would also be cool to have something show "User is deleting text from field X" when the field value is getting shorter.
In pseudo code, something like if the value of database string is bigger than 100ms ago, echo out "user is typing something in", and conversly, if string is getting shorter echo out "user is deleting stuff".
Basically i have a form with jqueryui implemented (autocompletes) and I need the form to display the number of current results as the user fills the form, i.e. once the user has finishedinputtingdata into one field, the form will query the database with the current form details and return just the number of results ($mysql_num_rows)
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.
You may use any descriptive text for DESC. I suggest limiting the description to 20 or fewer characters. The unit cost will be in dollars and cents. The amount is up to you, but keep the it in the range $0.50 to $100.00. Also, keep the item and the price somewhat realistic.
Create a form to access the database. There will be 2 input boxes, one for the SKU number and one for quantity. There will be 3 output boxes, one for the Description, one for the Subtotal (price x quantity), and one for the Total Cost (a sales tax of 7% added to the subtotal). There will be 1 button to retrieve the data and display the result (Description, Subtotal and Total Cost).
Is there a way to read from a page using a setTimeOut rather than a readyStateChange?
I have a PHP script, and it uses ob_flush to print the data as it comes up with it. I would like to use AJAX to read that data as it comes out, and update a percentage bar with the data returned from the PHP. The problem is, is that usual AJAX uses readyStateChange. And the only options i have are 1) It has started, and 4) Its done.
I have a php file... I click on the link, ajax generates a lightbox, I close the lightbox, then I click the link again and I am redirected to a new php file rather than loading the ajax. Here is my lightbox JS. Should this cause a conflict?
I put together this quick form that allows a user to sign up - the data.php just basically checks a mysql db if the username exists, and either-if it doesn't exist - create an entry in the database with the username, pw, and email and echo "Congratulations, you are added";-if it does exist - it echo "Sorry but 'xxx' is already taken, try again!";his is the weird part though. This works perfect in FF, but IE6 has a weird issue (I only have IE6 here can't test anything else) - With IE6, if the page is freshly loaded, it gives me the correct message - that is, if i put a non-existent name in, it does the echo"Congratulations, you are added"; but if I click on submit again - it doesn't echo "Sorry but 'xxx' is already taken, try again!"; (it does on FF) -If I start a fresh page and input a name that's already in the database it does echo "Sorry but 'xxx' is already taken, try again!"; -- but if i change the username to something that doesn't exist - it doesn't change the echo (i.e. it still says "Sorry but 'xxx' is already taken, try again!"; - but the record is created in mysql! code:
i am currently working on aptana studio nokia wrt plugin to develop a mobile widget where i need to retrieve data from database. i've created a java servlet in eclipse to connect and execute query to the ms sql server 2005 database. in aptana, i am using js file and html file, i'm able to connect to the servlet to retrieve and process the data (split the data) into an array and display the retrieved value (array) on screen. but now i need to put the retrieved value (array) into a drop down list for selection, how could i do that?
for the drop down list, i cannot define the list, it need to be able to read from the servlet as the database is updated, it need to reflect.
I know its primary function is to request information from the server, but can it also submit information? For example I have a page in which the user can drag and drop objects around (using DHTML) and I'd like to be able to dynamically store the coordinates of where they place the objects in the database without them having to click a "Save Changes" button ......
This hides the games the user doesnt want to see on the page. But before the game is hidden I want to make an Ajax call to the database and add the user's preference into the table so next time the user comes to the page I can hide the game from the start. How can I do this?
I'm trying to add a single test record (a comment item) to my MySQL database.The double f:ajax tags in commandLink body are to solve a problem, where I had to double click the button to reload content div.And now here comes similar problem:After loading the page, the first click of comment adding button never works - nothing happens. I was adding some logging methods into the addComment method and it is not executed at all on first click. I suspect it's caused by my Ajax reloaded div code, because when I launch such button on a plain page, it works good.Alternatively are there other ways of realizing panel refreshing instead of using ui:include tag, which might be causing the problem here?
I need an autosuggest/autocomplete script for my field Name..I search code for that but when I tried it in my webpage it did not work. I used smarty template, php and mysql-adodb. Is there any syntax that you can suggest for a simple autosuggest the data coming from database?
I have an ajax script that I would like to use to retrieve a password hint from a database.Both the ajax script and the php retrieval script are stored on the same domain (we'll call it domain1.com), but the ajax script runs on another domain (domain2.com).All the scripts are working fine, individually, but when I try to integrate them, I'm getting a ready state of 4, but an HTTP status of 0. I've traced the code flow and the retrieval script is being called by the ajax script OK and it's echoing all the right stuff, but it's just not getting back to calling ajax routine.
I've read that an ajax routine can only call a script that resides on the same domain that it runs on. Is this correct and, if so, does anyone know of a work around, because I really need to be able to store the ajax script on domain1 and run it on domain2?If not, then can anyone suggest why I'm getting an HTTP status of 0, when all the individual components are working fine?
