Can this be created in javascript. A timer?

JavaScript
245

Does this serve any purpose in the below code?
<a href="https://www.google.com/"></a>

<script>
console.time("Page load");
</script>

<a href="https://www.google.com/"></a>
<div id="report">Measuring...</div>

<script>
  window.onload = function() {
   console.timeEnd("Page load");
  }
</script>
246

No it doesn’t.

247

How would I be able to measure a sites speed externally? Without going under the hood?

248

That can’t be done without going under the hood.

249

How come there are a million sites where you can put your site in and it tells you how fast it loaded?

They obviously don’t go under the hood.

250

They use other techniques that are not available to client-side scripting. They use server-side scripting instead, using a variety of languages like PHP, or C# for example.

251

Would I be able to attach this to an iframe with a site in it and measure how fast that loads?

<script>
console.time("Page load");
</script>

<div id="report">Measuring...</div>
<script>
  window.onload = function() {
   console.timeEnd("Page load");
  }
</script>

Most sites use frame busting techniques that prevent that from happening.

There used to be a plague of sites that would put advertising around google, for example, so frame busting techniques were used to prevent external sites from putting them in frames.

How would you explain this phenomenon, please explain?

Click on the image links.

<div style="width:260;margin-top:8px;" onclick="myscr2=document.getElementById('myscroll2'); myscr2.style.display='block'; this.style.display='none'">

<a href="https://bloggersiteinsideiframe.blogspot.com/" style="background-image: linear-gradient( to right,#000000 0 ,#000000 83px,#0059dd 83px, #0059dd 86px, #000000 86px, #000000 174px, #0059dd 174px, #0059dd 177px, #000000 177px, #000000 260px );display:block;height: 168px;border: 3px solid #0059dd; cursor: pointer;   border: 3px solid #0059dd;font-family:Tahoma; font-weight: bold;font-size:30px; color:#0059dd;text-align: center;line-height:100px;text-decoration: none;" target="frame2">Links</a></div>

You mean, like the G+ image link that opens up to a separate window at plus.google.com ?

256

yes.

257

That’s a blogger site owned by Google inside an iframe.

258

What do you think needs explaining with that?

259

You said Google blocks the ability to do that.

260

Where did I say that Google blocks that?

261

here.

262

The G+ link opens a new window to:
https://plus.google.com/share?app=110&url=http%3A%2F%2Ftestpage34567.blogspot.com%2F2017%2F11%2Ffghgfhfghfgh.html

Which is something that is fully allowed. There are no cross-site frames involved there at all.

263

I was speaking about frames at that time. It has nothing to do with opening new windows to other sites.

264

You don’t see this?
