in a page ..there are 20 fields..i am showing definition of each attribute in a window pop up using window.open() method by clicking on the image using javascript.suppose one pop up is opened and then I clicked on some other's attribute image to see definition. so what it is doing just minimizing the first pop up not closing and then opening second pop up.similarly for any number of pop ups.
i need to close already opened window pop up (using window.open) before opening other pop up.
