javascript - How to open link in popup box?

Question

I'd like to open this link as a popup box:

  <a href="/upload/" onclick="window.open(this.href, 'windowName', 'width=500, height=350, left=24, top=24, scrollbars, resizable'); return false;">Upload pic</a>

Currently, it opens in a window, but what I want is a bare popub box instead. How to do so using js or jQuery?

Update: The link is inside a form group and using iframe, as suggested by many here, causes the form to submit (not sure why though). So I look for a non-iframe solution.

Answer 1

Build your own popup box with an iframe element;

onclick you can change the src of the iframe to the one you want

---

document.getElementById('modalBtn').onclick = displayPopup;

function displayPopup() {
  var popup = document.getElementById("popup");
  var frame = document.getElementById('popupFrame');
  frame.src = "https://www.bing.com";
  popup.style.display = "block";
}

#popup {
  width: 320px;
  height: 300px;
  margin: 0 auto;
  box-shadow: 1px 1px 1px 1px black;
  display: none;
}
#popup iframe {
  width: 100%;
  height: 100%
}

<div id="popup">
  <iframe id="popupFrame" src=""></iframe>
</div>

<button id="modalBtn">Display Popup</button>
