i am trying to evaluate some javascript after the click of a button in an iframe. The button is a link and the javascript is evaluated in the href of that link. It is not my choice to evaluate js in the href but i dont have access to any other attribute because it is an SSRS report. It seems however that no environment variables are defined in the scope of the iframe button, no console no documentnot even self. When i open the iframe report directly and not inside an iframe the scope of the button js includes all the important environment variables. I am attaching the code of the button.

Remember that is within an iframe, and the problem only occurs then. The below code generates a

uncaught exception: ReferenceError: self is not defined


<a tabindex="1" href="javascript:eval%20(%20%20%20%20%20unescape%20%20%20%20%20('self')%20)" style="text-decoration:none;" target="_top"></a>
