Asp.net cascading dropdownlist using jQuery ajax

Hi, Thanks for this tutorial. Hope you could solve my doubt. I am referring to following line from this link

http://www.aspsnippets.com/Articles/AJAX-Cascading-DropDownList-using-jQuery-in-ASP.Net.aspx

data 'continentId ' 'ddlContinents.ClientID'.val ''

in your code. i tried using this code and facing a tiny problem. In above mentioned code 'ddlContinents.ClientID'.val stores integer value in contentId for obvious reasons but the requirement of my code is different. i want to pass text which is selected instead of id no. for example if mumbai is listed as second option and i select mumbai it should store mumbai in contentId instead of 2 i.e. integer value. Any Help will be appreciated.

Thanks :)
