Question

I want to create javascript widget similar to linkedin Member profile. https://developer.linkedin.com/plugins/member-profile-plugin?button-type-inline=true

On my site the user can manage some data.
I want to allow for user to copy some HTML code and insert in his site HTML to display the data.

I want HTML code looks like:

<script src="http://mysite.com/code.js?userid=123"></script>

And if user inserts this code in his site then javascript code is loaded and data are displayed (widget displayed)

How to do this? I know about crossdomain restrictions. But in case of linkedin this is not the problem. Their widget works fine.

Thanks.

UPDATE.
As i understand from comments, it is not the problem to display any data in page that includes my javascript file. I am going to do tests.

Answer 1

Either the data is embedded inside the script, or it is loaded via JSON-P
