If your component is a MarkupContainer you can override getAssociatedMarkupStream(boolean) and build the markup on the fly. So maybe still have the HTML file that you read in as a template with some place holder string and in the override you replace the place holder with stuff you want to be assigned to the data variable. Then use a StringResourceStream to create a MarkupResourceStream, use SimpleMarkupLoader to create a Markup instance from the MarkupResourceStream, and finally create a MarkupStream with your Markup instance.
One thing to note is that if your markup container has child components that will be updated via AJAX AND you don't have an HTML file (you build the entire string on the fly) then you may also have to override hasAssociatedMarkupStream and always return true else the component being updated won't be able to locate its parent.

Suppose I write my own wicket component called XYZ that have the following markup <wicket:panel> <div wicket:id="id_xxx"> .... </div> </wicket:panel> How can I inject some js code into this markup so when it's rendered in a page, I got something like <wicket:panel> <div wicket:id="id_xxx"> <script type="text/javascript"> var data=["abc", "efg"]; document.write(data[0]); </script> ..... <div> <wicket:panel> You may ask why I dont simply keep the js code into the component markup "XYZ.html", this is because the value of "data" variable will be provided by the user and is not fixed.
