Hi Markus,

the Modalbox strips any script tags from the Ajax response before displaying the content.
But the scripts should still be evaluated in the current window context (modalbox.js lines 290 and 291). It seems to me the extractScript function only looks at the content of the tag, and it will not load anything remote, so your second example will probably not work.

I would try to include any scripts or css needed in the containing page or component.
ERXComponent has primaryJavascriptFile() and additinalJavascriptFiles() functions (and similar functions for CSS) to override in a component, that will dynamically insert corresponding script tags in the page header (but probably not when called with Ajax).

It’s getting weirder and weirder. Similar thing happens now with JS.
<script src = ....> </script>

does not even show up in WebInspector and thus my component fails miserably.

I think I am missing some basic (or might that be advanced?) understanding of html and the script and style elements.

This is the start of the html for the component that provides the content of the modal box

<webobject name = "updateContainer">

<script type = "text/javascript">

function just_a_dummy_function() {

alert('I am a dummy');

}

</script>

<script type = "text/javascript"

src = "<webobject name = datetimepicker_css_js />" >

</script>

<webobject name = "datetimepicker_js" />

<style type = "text/css">

<webobject name = "defaultStyles" />

</style>

None of the script tags show up in the web inspector.

The first one is hardcoded but the string “dummy” does not show up.

The second one resolves the webobject element as WOResourceURL. I expect this to result in something like <script src=“...

The third one (dateimepicker_js) is an ERXJavaScript with a filename binding

The last one gets the css definitions via a WOString, so all the defs are hard coded.

The only one that works reliably is the last one.

That’s so weird. Is there some magical incantation I need to utter next time full moon? Do I have to sacrifice my first born?

Please can anyone help me make some sense here?

I have an AjaxModalDialog that uses a component to render its contents (which itself uses a WOSwitchComponent to change the contents inside the modal dialog). Some things inside this component need special CSS defs that are in a css file. Using ERXStyleSheet allows me to load the css via filename binding -> works! WebInspector shows a proper <link rel = ... in the html

When the user closes the dialog and reopens it the ERXStyleSheets do not render again -> no <link rel = .... in the html, styles are now missing and the dialog contents looks wrong. A hardcoded <style>...</style> definition is rendered in any case, just the ERXStyleSheets do not anymore. Reloading the whole page restores everything.

Why?

I have now (UGLY like hell!!) resorted to <style> <webobject name = “styles” /></style> and resolve the styles in code by reading the style file (WOResourceManager helping to find the file URL) and returning its contents as a String.

Any idea? This stuff drives me crazy....
