i'm using an iframe for our project. when i run the project, the url will be http://localhost/iset/tech/mainTech.php. but mainTech is an iframe, so it doesn't show the url of the pages that changes inside the iframe. how do i show the url of the pages inside? cause i need to get the value of the links clicked in the other pages, but i cant because the url doesnt change. it is always http://localhost/iset/tech/mainTech.php.
