Passing Value to Java Script Code in a BSP

Hi Guys,

In order to use BSP Extension in my BS i need to specify the "ID" for the field / Text area / Table i want to work with.

Now these elements (Field / Text Area / Table) are created by SAP CRM automatically and i am not sure how i can get the name of the ID for such a element.

I tried using FIREBUG in firefox to get this ID but the problem is that this ID changes dynamicaly and i cant hardcode it in my BSP application.

Can anybody point help me taht how can i determine the ID dynamically at runtime and then use it in my BSP application.

Thanks in advance.
