Does anyone know how to set a javascript variable as a query result from a MySQL database.
As an example, like this:
Set this query:
I just can't do it. I've tried doing it like this:
But the thing stops my <body onLoad=""> function from working. I'm no expert in Javascript.
If I want to show the result of a database query, every second or so, is the best method using javascript/ajax with a set interval of a second to call a PHP script and update the DOM, or is there some other method better suited to this that would not have the cpu overhead if there were many users on the site.

I am having no luck with my post form to mysql. It is only posting the first letter of the word/phrase for the text input fields to the mysql database. It is a photo and text post form. The photo and only first letter of text are posting to database. I am using Jqtouch, jquery, and phonegap.
Here is my form fields:

i have a image that need user click on it and get the coordinates and store the coordinates to mysql database by using php. Here my code:

var mse=[ev.clientX-pos[0],ev.clientY-pos[1]];
var ary=this.ary;

Basically the user would see a button on a form that would be something like "add contact"...then a window opens that shows a search window (want to implement something like [URL]) and it would show all the contacts available in the contacts table...then the user selects the contact to add (via a link).
I think i could get it this far, but how would i then pass that $row to the main form so that i can use the fields from that $row in the contacts table on my form?
If I have a jquery var, such as:
var foo = $(this).fieldValue();
And within the </script> block I have a bit of PHP code that generates json, I want to pass the var to the php/mysql code such as:
Code:
$sql="Select from table where qid='foo'
In other words, how does a php/mysql query, in php code, grab the value of a previously declared Jquery var?
I work primarily with php, and haven't had much experience with JavaScript. I was wondering if JavaScript is suitable for automatically updating a database with the contents of a text area, at intervals of 3 minutes... without refreshing the page? It doesn't have to change the content of the text area, just take a snapshot of it. I am trying to develop an 'autosave' feature.

I am not a javascript programmer, however are checking as I would like to investigate if I can do following:
I have a calculator that check the price for the properties for a choosen date, I use php and mysql to get the result and the result are displayed on the same page refreshing the page using this in the form: action="<?=$_SERVER['SCRIPT_NAME']?>#formdestination">
I know you can print the result using ajax or other javascripts to do this without having to refresh the page and jump to the result.
Was doing a research and I quckly found this link:[URL]..It does not look so complicated, however as I can see the form is done in javascript so I suppose if you have javascript disabled you cant use the calculator.
I would like to have a non javascript solution with the way I am doing it to work if javascript is disabled. An exampel of the calculator can be viewed on this link for exampel:[URL]..
Firstly this isnt a double post, I stupidly posted in the Java forum not the java script forum. Im trying to create a dynamic table based on the selections of multiple lists as per here Screen Shot
A user would select thier choices from the various lists and then add them to a table - this is where my question comes in. How do I achieve creating a table which will grow depending on how many additions a user adds?
Hope I make sense, Im trying to get my head around this.
inserting a result of a SQL query into a html template.I've got a function which sends a query to a client side database und should afterwards show the result on the html side. Here is my function:
function refreshEntries() {

View 3 Replies View RelatedI have a form on a web page, with one field to enter a code, to search for a property.On clicking 'submit' I want to be able to run a script asynchronously in the background.The script will need to run a MYSQL statement which will have one of these results:
1. The property code does not exist, so display a Javascript Alert saying it does not exist.
2. The property is for sale, so call an existing javscript function 'saleSubmit(propertyCode)' to overwrite the exsiting web page with a new page sale.php for that property code
3. The property is for rent, so call an existing javscript function 'rentSubmit(propertyCode)' to overwrite the exsiting web page with a new page rent.php for that property code
My slills are in PHP and MySQL and I have no knowledge of tools like Ajax, jQuery and I am currently having problems getting my head around it. I have spent ages visiting lots of websites looking for examples on how to do this with little success.
I'm making a little CMS, and I need to use AJAX to query the DB to see if an email is already registered. Here's my code so far:
The javascript:
Code:
<script>
function getEmail(){
var ajaxRequest;
try{
ajaxRequest = new XMLHttpRequest();
} .....
I'll test it by entering javascript:alert(getEmail()) in my browser, and it returns undefined. When I replace return 'valid/taken' to alert valid/taken, it will alert the values correctly, but for some reason it has to be entered twice (I have to hit enter twice in javascript:getEmail() for it to be correctly outputted). I'm relatively new to ajax and I think it might have something to do with the readyState not being correct.
I want to ask you is it possible to use jquery dialog with php. Using this tutorial [URL] I want to call a php script with will delete a row into Mysql database.

View 3 Replies View RelatedI'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.
$("#submit_sign").click(function(data){
$.ajax({
type: "POST",
url: ("sign.php"),
[code]....
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 working on a project for which I need an autocomplete form which uses the value from a mysql database. I've seen many examples about using local data.
