1. When talking IE it is best to give ver number as they all work differently. I check the below code in IE8 and it works for me.
2. We are in the dark and have to guess if code is not supplied.
3. java servlets is for a different language, java not javascript.

What I check:

Code:

<!DOCTYPE html>
<html>
<body>
<p>Click the button to display a confirm box.</p>
<button onclick="myFunction()">Try it</button>
<p id="demo"></p>
<script>
function myFunction()
{
var x;
var r=confirm("Press a button!");
if (r==true)
  {
  x="You pressed OK!";
  }
else
  {
  x="You pressed Cancel!";
  }
document.getElementById("demo").innerHTML=x;
}
</script>
</body>
</html>

4. Such things as confirm boxes, prompt boxes, and alert boxes are not used much in programming anymore except for testing purposes.

confirm() is for debugging use only and is rarely needed even then so it doesn't really matter whether it works or not - it could be deleted from JavaScript now without having any real impact.

As the original poster said, he is getting the problem in JAVA servlets. Not JavaScript. So he is posting in the wrong forum.

I would assume, since he says the JAVA confirm() is being blocked by the popup blocker, that the JAVA confirm is, indeed, using a popup window and has nothing to do with JavaScript's window.confirm( ) method.

See, for example, the various kinds of confirm dialogs noted here:

Hi

thanks for the reply.

but i am unable to understand my prooblem...
please check the below to codes which i am using in two diffrent programs

1) first code is working on same IE

out.println("function popMessage(f)");
out.println("{");
out.println("if(f.chk.checked) ");
out.println(" if(confirm('If you click the Post button now the agreement will be removed from Action List '))");
out.println(" { }");
out.println("else");
out.println("{f.chk.checked=false");
out.println(" }");
out.println("}");

2) Second code is the problem code with popup blocker on IE

out.println(" if( info == '--') ");
out.println(" {");
out.println(" var x= confirm('Für diese Aktion wurden bereits Kosten verbucht. Sind Sie sicher, dass Sie weitere Kosten verbuchen wollen?”');");
out.println("if (x)");
out.println(" {");
out.println("window.open('Costreason.html', '', 'height=350,width=450');");
out.println("window.close();");
out.println(" }");

As has been pointed out, this is JAVA code so you have posted in the wrong forum. This is the JavaScript forum. Java and Javascript are entirely different programming languages, in spite of the confusingly similar names. Rather like Austria and Australia! Ask a mod to move this thread to the right forum.

But it is obvious that the problem lies with the literary quotes in

Kosten verbuchen wollen?”');");

That will barf in any browser, not just IE.

Ummm...Philip, although he is using Java to *write* the output, that's just server-side Java.

That server-side Java *IS* creating JavaScript, correctly.

Specifically, the second set of Java code is producing *this* client-side JavaScript for the browser:

Code:

if( info == '--') 
{
    var x = confirm('Für diese Aktion wurden bereits Kosten verbucht. Sind Sie sicher, dass Sie weitere Kosten verbuchen wollen?”');
    if ( x ) 
    {
        window.open('Costreason.html', '', 'height=350,width=450');
        window.close();
    }
}

It is true that he has a bogus "literary quote" mark in there, as shown in the large red text, but that won't hurt anything as it will be ignored by JavaScript (and Java, incidentally) and only the subsequent apostrophe will be used, correctly.

As shown, the code is missing one closing right brace } as I have indicated, but since he says the code works in browsers other than IE, it's probably really there in the actual code.

I really think he may be right, that his is a problem with a popup blocker.

********

On the other hand, the code also doesn't make tons of sense.

He opens the popup window for 'Costreason.html' but then *CLOSES* the CURRENT WINDOW. Why? If you only want one window to remain open, just *replace* the current window with the new one.
