            myImage.source = s as Class;

    &lt;mx:Button id="simpleButton" label="provideArray" click="{onClickfunc('helpDocs')}" /&gt;   
&lt;/mx:VBox&gt;

</mx:Application>

============

Q : Is there any way to somehow use the string value of onClickFunc function to use the class object with whom i embed the image . Like with passing “helpDocs” string , can I use that string value some how to access helpDocs:Class ??

Its not possible i guess but just out of curiosity
