<p>I have an array with three links for a button used in the footer and when I press the button again and again the array works fine one by one. . And a link button will appear every time it is pressed. That's fine.
But I want, when I click the button, <em> the "link" should open in an "iframe"</em>. . . I used iframe code to pass them src= button id but it doesn't work. . Please provide the code below and help. .
.

When generating the link's HTML, you can obtain it by specifying the name of the iframe in
target.So add a
nameattribute to your iframe like this:Then add a
targetattribute.document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '" target="iframe">' + link[intlinkIndex] + '</a>';function writeLink() { if (intlinkIndex >= link.length) { let btn = document.getElementById('btn'); btn.style.display = 'none'; mylink.style.display = 'none'; } document.getElementById('mylink').innerHTML = '<a href="' + link[intlinkIndex] + '">' + link[intlinkIndex] + '</a>'; document.getElementById('iframe').src = link[intlinkIndex]; intlinkIndex++; }Complete source code
