Running PHP/MYSQL Script Asynchronously And Taking Action Based On Result?
Mar 25, 2011
I 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 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]..

Does anyone know how to set a javascript variable as a query result from a MySQL database.
As an example, like this:

But the thing stops my <body onLoad=""> function from working. I'm no expert in Javascript.

I want to display three sets of images on a Web page, and I want to use only one jcarousel to do it. I want to change the list of images based on the user clicking on one of three links, each representing a set of images. How do I do this? I know I can edit the DOM to modify the list of items, but how do I call jcarousel's reload() function? I thought of using three instances of jcarousel, but that takes up too much screen space and requires the user to scroll too much.

The following code is supposed to provide a different alert message when a page is loaded, based on a random number generated on load. Can anybody see what is probably a very obvious problem that I just can't see?[code]

I have a form which I need submit using ajax. I already got all the needed query from that form, but when I tried get the action address I got [object HTMLInputElement] instead of expected address blah.php.
Here is a quick example to demonstrate this behavior:
Code:
The problem is that I named the button as "action" and this.action is returning the button object instead of the action of the form.
I can't remove the form element with name "action" from that form because of the script that accepts the data, but I need get somehow the form's action (url).

I want my submit button to link to different pages, based on the value of a particular variable (let's call it total).
So, if 18 < total < 20, the submit button should redirect to page1.html
If 16 < total < 18, the submit button should redirect to page2.html
If 14 < total < 16, the submit button should redirect to page3.html
I have created page1.html, page2.html....page10.html. how should I link my submit button (I have only *one* submit button) to different pages based on different conditions?

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.

To give you a little background about myself, I am a complete JavaScript novice. I am used to SQL scripting a little. We have recently moved to a web IT Service tool, we have taken on the programming of this tool and it is mostly using JavaScript. Within my tool I am trying to create a field to display the financial Period Number, based on the open date of a task using a 4 weekly rotation. Therefore what I am trying to code is;

Let me preface this by saying that I have ZERO experience with Ajax, and have simply copied this code from a blog elsewhere. What is shown below ties to a php file that I developed for a search function on our site. As the user enters their search term(s) in the text input field, the div below is populated with potential results through AJAX. I get all that.
However, I'd like to extend this a bit more. I'd like to enable to user to click the Enter key to follow the URL of the top search result automatically, without having to move their mouse and click on it.
Since I'm using PHP to generate the actual URL, I'm sure I can just send this back as a variable via AJAX, but with my lack of understanding, I thought I'd poke around here for some assistance. Can someone show me how to tweak the code below to accomplish what I'm looking for?
Code:
<script type="text/javascript">
function showResult(str)
{
if (str=="")
[Code].....
I'm less concerned about getting the Enter key to perform the submit than I am about passing the URL variable back to the form via AJAX. I've seen lots of examples of getting the Enter key to behave this way, I just didn't want to muddy up the original code above.

Is it possible to disable the default action of the mouse scroll....and use the up and down scroll of the mouse to change the content of a Div.....(usually text)? The page would be designed to have all content 'above the fold' and scrolling down the page would not be necessary.

I am trying to reload the contents of a div asynchronously using jquery. It works fine if the link/button to do so is outside of the div I am reloading, but I need the button to be inside the div I am reloading and it does not work if I do it from there. I have thought about overlaying divs but I need the buttons to be very exactly positioned as its a graphical representation of a map and recoding the way the buttons are placed would not only annoy me but be very difficult.
You see its an isometric view of a square, and the buttons need to be placed right along the edges of the 'diamond' therefore always coming inside or on top of the div that contains the map view. So, is what I am trying to do impossible or might I just be going about it the wrong way ? If it is the latter then I will post some code.

I have come across a very interesting problem that seems to be impossible to solve. Basically a web application that I am working on relies on a JavaScript function called go to change the input named view to the page name and submit the form. This form's type is post, so no values are included in the actual URL string. There is also another input called action and it's value is view. This is to tell the application that the user would like to view a page. The problem is because of the variables being of method post, page refreshes and back and forwards return errors because the post variables view and action aren't sent with the required data. To somewhat solve this problem I have created a feature that tells the application that if the post value page is empty then to try and get a GET var called page. To insert this var into the go javascript function I simple add this code
document.go.action = document.go.action+"&page="+page;
This line basically adds &page=[page] to the action of the form. The problem is, this code doesn't work because action is also the name of a form element. Referencing document.go.action refers to the input element named action and not to the form's action. Changing the named of the action input value is out of the question (Way to much changing of code, and possible room for error). What can I do to change the action of the form without referencing the input named action. Here is my go form and the JavaScript code:
<form name="go" action"index.php?sid=123" method="post">
<input type="hidden" name="action" value="view" />
<input type="hidden" name="view" value="" />
</form>
[Code]....

I have created a site that my friends and I are using and Im trying to implement a simple image slider.
I can do this without any issues in its simplest form. The issue though is that there are 10 people posting pictures and the site displays their last 6. What I want to do is create a button after each row that allows the user to scroll through that users pictures, but i dont want to preload all images first as this will make the page slow.
This image shows what I maen - the black arrow would make that particular row scroll right - loading images as it went.

I have a php file that generates different content based on a get variable in the url. test.php?foo=bar1
I'm loading this into a div on my site with
<script>
$(document).ready(function() {
$("#result").load("test.php?foo=bar1");
});
</script>
Well that works, but i want to add a select option <option>bar1</option> option>bar2</option>
And depending what option is selected, i want to load that get instead. So if bar2 is selected, the load should (asyncronosly) load test.php?foo=bar2 instead.

With the following code I'm loading images asynchronously into an html document.
$('input.src:hidden').each(function()
{
var img = new Image();
$(img).load(function()
{
[Code]...
As you can see there are some hidden fields in the document that hold the source locations of the images.By looping trough them the images are being loaded, but not as expected. I'd expect them to always be in the order of 18, 19, 20, 21 but instead of that images get loaded, well for as far as I can see, pretty randomly.
