I have a line of code:

Response.write("<script language=""text/JavaScript"">alert(""What up dog"");</script>")

This doesn't work. I see no alert box, yet I see the page source has written the code correctly:

<script language="text/JavaScript">alert("What up dog");</script>

What I'm actually trying to do is this:

Response.write("<script language=""text/JavaScript"">document.cookie = '" & Cookie & " = ; expires=Thu, 01 Jan 1970 00:00:01 GMT;';</script>")

That is: Delete a cookie with the name stored in the ASP variable 'cookie'. This doesn't work either, which is why I'm attempting to create the alert box just to test where I'm screwing up.

I've tried deleting the cookie with pure ASP (Response.cookie(Cookie).expires = Now() - 1), but since I made the cookie with JavaScript, it's not HTTPOnly so I can't access it with ASP. (I just learned this, so I'm not 100% on the why of it all, but there it is.)

So, back to the first line of code, why am I not seeing a JavaScript alert box with that line of code? I'm obviously missing something simple (it's always something simple).

• 1 You should be able to access the cookie from the server, HTTP-Only or not. – Pointy Commented Jan 22, 2013 at 13:59
• 1 When is the first line processed? JavaScript won't just run when injected into the page. It needs an event to trigger it. – isherwood Commented Jan 22, 2013 at 13:59

• @Pointy: stackoverflow./questions/4999360/… <-- That's where I gleamed that tidbit of information. – JGGR13 Commented Jan 22, 2013 at 14:14
• @JGGR13 you made an incorrect inference - HTTPOnly means that only the server can read the cookies; if that's not set, then both the server and the client can read it. – Pointy Commented Jan 22, 2013 at 14:16

The language="" attribute for <script/>-tags is deprecated and erroneous values prevent scripts from being executed in many browsers.

To me it looks like you were heading for the type="" attribute.

Try the following code:

Response.write("<script type=""text/javascript"">alert(""What up dog"");</script>")
