I have a list of items and a button with each to display more detail in an iframe model. The button sets the URL in the modal control.
The first invocation works fine, but all subsequent ones on the same page use the original URL. I verified in the Chrome inspector that the URL was indeed changed.
Once a modal is initialized, it will simply re-open. Not reload.
But why are you going about it this way?
Why not simply make the 'DETAILS' buttons Modal links?
What is the idea behind trying to reuse a single modal link for different pages?
