redirect and open as modal by using javascript
<p>I have three pages, page1 you are not allowed to add javascript but it has a button when you click it, it goes to page2, in page2 you are allowed to have javascript but it is not modal. </p>

<p>What I want to do is when you click the button in page1 it opens page3 as modal by javascript, so I have to add javascript to Page2 so that it goes back to page1 and opens page3 as modal without user notice page2. thanks for your help.</p>
