Multiple onload problem

32 New Member

On this page:
http://jimpix.co.uk/default-ajax1.asp

When viewed in IE6, only the wallppaper ajax section (which is 1 of 4 ajax sections, along with ecards / news / photo ecards and wallpapers), loads.

But in Firefox, they all load, when first loading the page.

I am using this method to load all of the functions on first loading the page:
http://www.netlobo.com/wom.html

My javascript functions are at the bottom of the page. Could the problem be to do with my first function - since this issue seems to be browser specific.

Thanks

 function GetXmlHttpObject() {

  var xmlhttp;

  if (window.XMLHttpRequest) { // Mozilla, Safari, Opera...

    xmlhttp = new XMLHttpRequest();

    //if (xmlhttp.overrideMimeType) xmlhttp.overrideMimeType('text/xml');

  } else if (window.ActiveXObject) { // IE

      try {

        xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");

      } catch (e) {

          try {

            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

          } catch (e) {}

      }

  }

  if (!xmlhttp) {

    alert('Cannot create an XMLHTTP instance');

    return false;

  }

  return xmlhttp;

}
 
var http = GetXmlHttpObject();

womAdd() requires strings. Put quotes around the function call.

Thanks for the reply. I have changed that, but for some reason, the page works fine in Firefox, when it first loads, but again, in IE6, it only displays the last of the 4 functions - the one in bold.

[HTML]<script type="text/javascript" src="_wom.js"></script>
<script type="text/javascript">
womAdd("sendReq uest(MyCurrentV ar + ',' + MyCurrentCat)") ;
womAdd("sendPho toRequest(MyPho toVar)");
womAdd("sendNew sRequest(MyNews Var)");
womAdd("sendWPR equest(MyWPVar) ");
womOn();
</script>[/HTML]

And if I comment out the bold line (calling the 'sendWPRequest' function), IE6 will display the 3rd function, but ignore the 1st and 2nd!

I uploaded the revised page again:
http://jimpix.co.uk/default-ajax1.asp

Thanks again

It seems that IE6 is overwriting the onload. Try using this script and see if it makes a difference.

Thanks acoder, again, for your helpful suggestion and feedback.

I gave it a try, but would you believe it, just the same result:
http://jimpix.co.uk/default-ajax1a.asp

I think that's the 4th method I've tried now:

1. multiple list on the onload in the body tag:
[HTML]<body onload="sendReq uest(MyCurrentV ar + ',' + MyCurrentCat);s endPhotoRequest (MyPhotoVar);se ndNewsRequest(M yNewsVar);sendW PRequest(MyWPVa r);">[/HTML]

2. Use the window.onload:

Expand|Select|Wrap|Line Numbers

 window.onload = function()

{

    sendRequest(MyCurrentVar + ',' + MyCurrentCat)

    sendPhotoRequest(MyPhotoVar)

    sendNewsRequest(MyNewsVar)

    sendWPRequest(MyWPVar)

}

3. Use the NetLobo option:
http://www.netlobo.com/wom.html

4. Use Simon Wilson's option:
http://simon.incutio.c om/code/js/addloadevent/

Do you think it just can't be done?

Thanks again for your help

Then it must be that you're reusing the http-request object, so it doesn't finish one and starts another. Either use different variables for each one or wait for one to finish before making another request using the same variable.

Dear acoder,

you are a star! Thank you so much for your help. That was the problem all along. I created different variables for each function, and it works a treat now, in IE6 and Firefox. Thank you again, what a helpful person!

Web pages with multiple grids and validation controls - confirm delete problems

by: Richard Payne | last post by:

I am developing a web application that utilises multiple grids, panels, validation controls etc on the same page. I have added the appropriate code to pop up dialogs to confirm delete in datagrids using the ItemCreated event, template colums and the Button.Attributes.Add ("onclick", "return confirm('Are you sure you wish to delete this row?');"). This works fine in some instances when you click on the delete button but not always.

The easy way to turn off automatic updates for Windows 10/11

by: Hystou | last post by:

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
