Javascript Window.Print() doesn't return to URL with Querystring attached

I have a simple button on my web page that does onclick="window.print();" and it works well.  However when the print is completed and the view is returned to the page, there is no Querystring after the URL.  It just says "http://myweb/rego.asp?" rather than "http://myweb/rego.asp?eid=55".

Some help would be wonderful.

is it a button or link element you're using to trigger the print?  Can you please post the html you're using to trigger it.  If you are using an anchor <a> element then you'll need the href="#"

  <button onClick="window.print();">Print</button>

Open in new window

Current page URL is ""

When it returns to page it seams to refresh with ""

Your pages are html pages whereas mine as classic asp.  I'm wondering whether asp pages do a 'refresh' once the print function is finished (or cancelled).  So I checked to make sure there was no 'onload' functions or the like or any javascript that might be affecting this.  All I could find is the following piece of code at the bottom of my <head> section.  I'm not sure why it's there or what it is achieving.

//Page Highlighting
var url = window.location.toString()
  $('ul li a').each(function(){
    var myHref= $(this).attr('href');
    if( url.match( myHref )){

Open in new window

All that you've mentioned shouldn't affect the issue you're having.  I'm not an asp dev but I am aware of partial postbacks.
Can you post the link to your site or send me a private message with the link to the page? I'll get a better idea with that

It is possible the button is submitting to current page.


  <button onClick="window.print(); return false">Print</button>

which is what you also would do on a link

Michel, I think you're on the money with that one.
Try changing your button to a link as confirmation of what Michel is saying. A link should give you the desired effect.
I do remember that a button within a form will submit it when the type is omitted (as Michel had indicated in his post)

Perfect!  I suspected a return parameter but had tried 'True' instead of 'False'.  Duh - makes sense now thank you.
