you need to use iframes

<div class="iframeContainer">
  <iframe src="newPageTobeIncluded.html"/>

Thank you gurvinder372, i really want to keep away from iframes as must of the browsers dont support them.

There really is no way of doing it without?
The best way to make and keep the code clean (ie without the iframe) is using  ajax ...
What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Thank you MYfox.

Can you help me how to do this?

Lets say i have a include page in the middle of the webpage and it is already pointing to default.aspx?pageid=1

Now if you click on a link that then displays default.aspx?pageid=1&mysite=me&do=uk


You might want to consider an ajax solution:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">

jQuery(document).ready( function () {

  $(".dynamic").click( getContent );


function getContent( event ) {
  $("#dynamic-content").load( $(this).attr( "href" ) );


#dynamic-content { width: 640px; height: 400px; border: 1px dotted #f00; margin-left: auto; margin-right: auto; overflow: scroll; background-color: beige; }


<a href="http://www.whatcar.com/Valuation/SelectMake?makeId=4708" class="dynamic">Alfa Romeo</a> |
<a href="http://www.whatcar.com/valuation/SelectMake?makeId=5202" class="dynamic">Aston Martin</a> |
<a href="http://www.whatcar.com/valuation/SelectMake?makeId=5289" class="dynamic">Audi</a> |
<a href="http://www.whatcar.com/valuation/SelectMake?makeId=28656" class="dynamic">Bentley</a> |
<a href="http://www.whatcar.com/valuation/SelectMake?makeId=6805" class="dynamic">BMW</a>

<div id="dynamic-content"></div>


Open in new window

Hi everyone.

I have been trying to get it to work with very little luck, so spent more time researching and come up with a solution from w3schools, however, i have changed the code but still can not get it to work.

I have my file in asp.net, if quesrystring = me, me1 or me2 then i should display something

If Request.QueryString("q") = "me" Then
            Response.Write("Number 1 selected")
        ElseIf Request.QueryString("q") = "me1" Then
            Response.Write("Number 2 selected")
        ElseIf Request.QueryString("q") = "m2" Then
            Response.Write("Number 3 selected")
            Response.Write("Nothing selected")
        End If

On the page that this will be displayed i have

<script type="text/javascript">
function showCustomer(str)
var xmlhttp;    
if (str=="")
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  if (xmlhttp.readyState==4 && xmlhttp.status==200)

Within the boty i have

<div id="txtHint">Customer info will be listed here...</div>
                <a href="javascript:showCustomer('me')"> 1</a>

However it still does not go of and bring the data back.

Please can anyone help me.

Thank you all, but i now have it working and bring the information accross.

Basically, the above worked, but i was trying to bring accross an entire page and not just the code itself.
