Div: Load data from external file with Ajax

Hello,

In my template I've 3 radio buttons whic are activating 3 divs. Till now I was using iframes inside these blocks to pull data, but now I want to avoid using iframes. Is there any alternate way to load external data in div? I seen that jquery has a function load(). Can it be used and how? The way that I was using iframes was:
... src="myfile.php?do=categories&catid=xx.... I want to keep this type of URL.

Thank you

just replace /path/to/your/page jquery_selector_to_grab_part_of_page_if_needed
by the url of the iframe you want to display

if the content is external to you site you can't use jquery.load (without some work on your webserver) due to cross domain/protocol/port ajax restriction
you may use a proxy on your server to download the data for you
the main difference with frame is the interactivity

By saying external I don't mean in different domain, not even in different directory. It's just another file. Is not static content.

ok go for jquery.load but if you've a link and click on it you left the current page
this is the difference with iframe

$("#div_ID").load("/path/to/your/page jquery_selector_to_grab_part_of_page_if_needed");

If it helps, below is my code. First of all there is a function which determines the user's screen resolution and activate one of the 2 first divs. But there are another 3 radio buttons that user can selects:
<html>
<head>
<script type="text/javascript">
function SetResState()
{
    if(screen.width <= 1024)
    {
        document.getElementById('rgrid1').checked =true;
        document.getElementById('rgrid2').checked =false;
        document.getElementById('bgrid1').style.display = 'block';
        document.getElementById('bgrid2').style.display = 'none';
    }
    else
    {
        document.getElementById('rgrid1').checked =false;
        document.getElementById('rgrid2').checked =true;
        document.getElementById('bgrid1').style.display = 'none';
        document.getElementById('bgrid2').style.display = 'block';
    }
}
</script>
</head>
<body onload="SetResState();">

<input type="radio" id="rgrid1" name="rgrid" value="1" onclick="document.getElementById('bgrid1').style.display = 'block';document.getElementById('bgrid2').style.display = 'none';document.getElementById('bgrid3').style.display = 'none';document.getElementById('bgrid4').style.display = 'none';document.getElementById('bgrid5').style.display = 'none'">Short

Sorry but I can't get your meaning. Where I must place that code? And for sure I need to enter < script > ... < / script > before and after. Right?
jquery_selector_to_grab_part_of_page_if_needed ... My file is using do=xxx. What I need to enter? Just do=xxx or jquery_selector do=xxx ?

To make the long story short. Let's say that my iframe url, was:
classifieds.php?do=browse&catid=1
Now I must write:
<script>
$("#div_ID").load("classifieds.php do=browse&catid=1");

your buttons :
<input type="radio" id="rgrid1" name="rgrid" value="1">Short
<input type="radio" id="rgrid2" name="rgrid" value="2">Wide
<input type="radio" id="rgrid3" name="rgrid" value="3">Brief
<input type="radio" id="rgrid4" name="rgrid" value="4>Full
<input type="radio" id="rgrid5" name="rgrid" value="5">Gallery
your div :
<div id="YouNeedOnlyOneDiv"></div>

Open in new window

good to put the following in the head section
<script src="http://code.jquery.com/jquery-1.6.2.js"></script>
<script>
$(document).ready(function() {
       $("#rgrid1,#rgrid2,#rgrid3,#rgrid4,#rgrid5").click(function() {
              var n = parseInt( $(this).attr("id").replace(/\D/g,"") ) - 1;
              var urls = ["url_frame1","url_frame2","url_frame3","url_frame4","url_frame5"];
              $("#YouNeedOnlyOneDiv").load( urls[n] );
       })
})
</script>

Looks good at: http://www.christeris.net/vb4/classifieds.php?do=main&catid=4
The only problem is that the function that I had to preselect one of the first 2 divs according to user's resolution is not working.

leakim971PluritechnicianCommented:
this is how you load the content with the first URL :
$("#YouNeedOnlyOneDiv").load("classifieds.php?do=browse&catid=1");

Tell me something is I'm already late in my project. If I let them as is right now, and in every div that I've (even if they're more than one), I place the follwing code:
<div id="grid1">
<script>
$("#YouNeedOnlyOneDiv").load("classifieds.php?do=browse&catid=1");
</script>
</div>

Open in new window


Should be ok???
PS- Didn't found any script with that id. Give me a link to the script that you're reffering.

To activate the 1st or 2nd URL depends on the end users screen resoloution. So, I don't know it, and from the other side I don't know how to modify the other function. In general I know nothing from javascript :-(

Didn't got your meaning, but thank you for your help. I'll accept your solution. I'm sure that trying in real according to your advices, I'll make it to work. But don't forget that not all are Guru or Experts, and most important, not all have as tongue language English, so we need to read more than once to get the full meaning.
