Adding Items to selected value in listbox at page load

Adding Items to selected value in listbox at page load

Hi,

I am using ASP.NET 3.5, C#. I have jquery version - jquery-1.8.3.min.js
 
I have a listbox which has title as "Inform user groups". The list box contains 20 values in the left side. On the page load, i would like to put 2 values to the selected items in the listbox( on the right side). The values to be put are "PM", "Senior Manager".

The title of the left side list box is : Inform user groups possible values

title of the right side list box is: Inform user groups selected values
 
The values in the first listbox is of the following format:
tPM|t |t |t36|tSenior Manager|t

How to achieve this using jquery?

Thanks
