Dynamically adding new <script> element.

Hi,

There's unexpected result when I tried to add new <script> element.

Here's a code snippet:
  page.executeJavaScript("var script = document.createElement('script')");
                page.executeJavaScript("script.setAttribute('type', 'text/javascript')");
                page.executeJavaScript("script.text = 'var execSpec = 42;'");
                page.executeJavaScript("document.head.appendChild(script);");
                page.executeJavaScript("document.head.removeChild(script);");

                System.out.println(page.executeJavaScript("window.execSpec").getJavaScriptResult());

The result should be '42', but it returns 'undefined'. It works fine on web browsers.

Actually, this is a part of Mootools library code, "core/Browser.js":
 function $exec(text){
        if (!text) return text;
        if (window.execScript){
                window.execScript(text);
        } else {
                var script = document.createElement('script');
                script.setAttribute('type', 'text/javascript');
                script.text = text;
                document.head.appendChild(script);
                document.head.removeChild(script);
        }
        return text;
 };

I'm working on HtmlUnit 2.1. Is it fixed?
I cannot try this on head version.
Head is fail to package because of failed test.

Regards,
Sung-Ahn Kim.

Dear Sung,
 
The following case fails with FF2, it gives 'document.head has no properties'.
 
BTW, just recently: "JavaScript: window.execScript() now accepts undefined 'language' (IE only)." Because in the specs, execScript should have another string language.
 
Anyway, running the below case with head HtmlUnit works correctly.
 
Please advise if you have an issue.
 
<html>
<head>
<script>
  function test() {
    execMe('alert(1)');
  }
  function execMe(text){
    if (!text) return text;
    if (window.execScript){
        window.execScript(text);
    } else {
        var script = document.createElement('script');
        script.setAttribute('type', 'text/javascript');
        script.text = text;
        document.head.appendChild(script);
        document.head.removeChild(script);
    }
    return text;
  }
</script>
</head>
<body>
<input id=myId type=button onclick='test()' value='Test'>
</body>
</html>

As Ahmed said, please try HEAD. If you're having trouble with the unit tests, you can skip the tests via Maven (-DskipTests with the latest versions). See the Maven docs for more info.

Sorry, Ahmed.
I missed important portion of the mootools library code.
They define 'document.head' but the htmlunit cannot recognize it.

And, unfortunately it doesn't work on htmlunit with FF2 configuration.
(It works fine on IE configuration)

Oh, I'm working on htmlunit 2.1 and 2.2-snapshot.

Here's my code:
----
<head>
        <script type="text/javascript" src="../Source/Core/Core.js"></script>
        <script type="text/javascript" src="../Source/Core/Browser.js"></script>
        <script type="text/javascript">
                function test() {
                        $exec.call($exec, 'var execSpec = 42');
                        alert(execSpec);
  }
        </script>
</head>
<body>
<input id=myId type=button onclick='test()' value='Test'>
</body>
</html>
----

You can see the mootools code from the repository (Core.js, Browser.js):
http://github.com/mootools/mootools-core/tree/master/Source/Core

I know to see the external link is quite bothering you. Sorry, but its content somewhat large to paste.

Dear Sung,
 
It has been fixed in SVN, please give the latest snapshot a try and advise if you have any other issue with MooTools.
Thanks a lot,
