Adding javascript to popups

chrscote · #1 (**permalink**) June 3rd, 2005, 08:39 AM

I have a stand-alone Flash training application that is opened as a popup from another HTML page. If the student clicks on the Windows close button, I want to have an alert telling them that they're not allowed to do that. I've been trying to add a fairly simply javascript to the popup code, but I keep getting errors saying that I have an "Unterminated string constant" on the line that reads:
        "<script>"+

Here is a portion of the code:
function openPop() {
    NFW = window.open("","popFrameless",s)
    NFW.blur()
    window.focus()
    NFW.resizeTo(windowW,windowH)
    NFW.moveTo(windowX,windowY)
    var frameString="<html>"+
    "<head>"+
    "<title>"+title+"</title>"+
    "<script>"+
    "function checkExit() {"+
    " //Do something here
    "}"+
    "</script>"+
    "</head>"+
    "<body onBeforeUnload=\"javascript:checkExit()\"></body></html>"
    NFW.document.open();
    NFW.document.write(frameString);
    NFW.close();
    }
}

Is there a way I can get around these errors?

<BODY onLoad="top.window.focus()">

<a href="javascript:openFrameless()">Click Here</a>

When writing script via a string you break up the script word to prevent confusing the parser:

Code:

"<script>" ... "</script>"

=>code]
"<scr" + "ipt>" ... "</scr" + "ipt>"
[/code]
I believe it's not necessary for both but I do it anyway as I can never remember which one...
