There is a frame were a website will open i want that all links in the website is disabled except the one link suppose it to be a login link. Is it possible to disable all the links except one. So,this is what that is required.

<a href="" id="link_t" >link for exam</a>
        <iframe  id="frame" style=" width:100%; height: 700px;    margin:30px 0 0 0px;
          border-style: none; " src="" ></iframe>

on js file code is

var link_on_page=document.getElementById('link_t');
var divv=document.getElementById('frame');
link_on_page.addEventListener('click', function(e) {
    e.preventDefault();
        divv.src= "some_link"; 
    requestFullscreen(document.documentElement);
   });

I am calling third part website in a frame and do not want that links should open just the login link only just want to diable all links except the one on the third party website.

Disabling all links can except one can be accomplished like so:

function disableAllLinks(){
// x now contains a live collection of anchor elements
let x = document.getElementsbyTagName('a');
let j = 0;
while (x[j]){
x[j].setAttribute('href', '');
j++
}

Then enable the reference you want using the same idea but with

x = document.getElementbyId('someId');
x.setAttribute('href', 'linkgoeshere');

This is just a quick simple example that uses the DOM You would then include a call to the function in the 'onclick' event function that loads the new page.

  • The iframe is a different `document`; this would need to run against the iframe's `.contentDocument.body` (if it were a first-party iframe.) – Daniel Beck Feb 03 '18 at 19:27
  • Sorry I assumed the link was outside of the iframe, because the code is incomplete; it looks like the link is not included in the iframe and the question is not in very clear and concise English I just gave a quick basic example on how it is done – Matthew Lagerwey Feb 03 '18 at 20:23
  • gah, you might be right, rereading the question I really can't tell anymore – Daniel Beck Feb 03 '18 at 20:29
