    You will need to have a javascript variable which holds current cart status. Make it either 1 / 0 flag OR total number of items in cart OR whichever way you feel good.

    When user tries to leave off, check the variable status first and then decide whether exit popup to be displayed or not.

    like to clarify more here

    When cart is not empty, I will make javascript variable say

    var cartempty=1

    I have javascript onunload="onul()" which is called when page leave

    In this function i need to check for cartempty variable value

    if cartempty =1 (display message)
    else
    no Message

    Yes, that seems on track.
    Try implementing it and lets resolve difficulties you may face.
