in this last couple of months one of my missions were to pass parameters to QlikView Objects...
With the help of a colleague and with a few more approaches i got as the final result, a set of three html scripts to test the passing of parameters to the QlikView Objects.
First thing you open the html in notepad or notepad ++(my favorite) and change your settings: your server, your document, your object and your parameter (year, month,etc.).
Down a screen of the script working... before and after the parameters passage...
Inside the zip you have the example for Documents, Objects and a Group of Objects using this: http://community.qlik.com/blogs/qlikviewdesignblog/2013/06/14/making-qlikview-part-of-the-story-embedding-objects-into-web-pages
I hope this could be useful four you...
For parameters passage when invoking the html you just have to use: ....html?parameter=xxx
