What I mean is letting people see the page before linking so they know what's going to be on that page. Picture a small window taking a look at a page before you open it.

asked for a small “peek” of a page before the user opens it. The community has already sketched the three realistic routes — live embed, client-side render, or server-side snapshot — so below are specific, practical options, tradeoffs, and quick examples tied to those suggestions from , and .

A simple in-page thumbnail (fast, live) works when the target allows framing. Scale an embedded page with CSS and disable clicks so it behaves like a preview; enable interaction only on explicit user action:

/* container sized to thumbnail */
.preview { width:300px; height:200px; overflow:hidden; }

/* iframe scaled down; pointer-events stops clicks */
.preview iframe {
  transform: scale(0.25);
  transform-origin: 0 0;
  width:1200px; height:800px;
  pointer-events: none;
}

For same-origin pages that you control, a client-side render library can snapshot DOM to canvas; see html2canvas for details (html2canvas). This avoids a full remote render but is limited by cross-origin resources.

For external sites or reliable thumbnails at scale, use a server-side renderer (recommended). Typical flow: server fetches the URL, renders with headless Chromium, captures a scaled screenshot, caches the image, and serves it to clients. Puppeteer is a commonly used tool for this (Puppeteer).

Key gotchas and tips:

  • Many sites block framing with X-Frame-Options or CSP frame-ancestors; detect this and fall back to a server-side image (X-Frame-Options).
  • AJAX cannot read cross-origin pages without CORS due to the same-origin policy (same-origin policy).
  • Cache thumbnails, respect robots and rate limits, and update periodically instead of rendering on every hover (as warned about storage/CPU costs).

For external links, a server-side screenshot plus caching is the most robust approach; for internal links, a scaled iframe preview with pointer-events control is the simplest and quickest to implement.

There are so many potential answers to that particular question, it's impossible to say without some sort of context.

If you want to interact with the page, use an iframe

If you want just a preview of it, use an ajax load
and if you want a scaled preview that you can't click on, use images - ajax load will actually load the DOM elements of the body of the site you give it

Sorry if my question didn't make sense but this user got my idea of my project. I want to create something like a preview page so people can see what's on the page before clicking in JavaScript. If that's possible? I will take a look at Ajax language though

Unless you create a snapshot image of every page of interest to be displayed on hovering a link to it, there would be no benefit in doing so, because every other mean would require an actual download of the target source before you get it displayed on whatever you may have decided to display it onto.

But I'm pretty sure you may be able find scripts that generate thumbnail images already available on our wast www.

Javascript alone won't provide an effective solution. A server-side resource is required, accessed via AJAX (which is a technique not a language).

Many third-party resources exist or you can install one of several well developed scripts (in eg PHP) on a server under your own control. Google eg. "url thumbnail preview" for online resources.

I would suggest that this only makes a viable project if you have an internet-connected server at your disposal, and you are prepared to write/install a server-side script in addition to client-side (javascript) coding.
