#script tag

Hi! Do you know where to find Agents of Shield-scripts online?

Hi, nonnie! As much as i wish i could tell you, unless they’re released by the official AOS Twitter or from one of the writers directly, they have that shit under lock and key!! Copyright stuff is important to marvel especially, so they’re really hush hush with their scripts. Are you looking for any one scene in particular?

What are the async and defer attributes on the script tag?

When the browser’s HTML parser bumps into a <script> tag, normally, it will pause HTML parsing and wait for the <script> to both download and execute before resuming. 

This is usually why we would want to have <script> tags at the bottom of our html right before the closing </body> tag.

However, we can use async and defer to modify the behavior for better performance.

By using defer, we tell the HTML parser to continue parsing while the <script> downloads or loads. Then, when the parser is done at the end, the <script> will execute.

By using async, we tell the HTML parser to continue parsing while the <script> downloads or loads, then when it has finished, the parser will pause while the <script> executes.

As you probably know, the script tag is used for specifying JavaScript which should be run in a webpage. A script tag can either include the JavaScript directly, or it can point to a URL where the script should be loaded from...

crossorigin is a thing too!

It’s not fully standardized yet, but there is a crossorigin attribute which is supported by some browsers. The general idea is that the browser doesn’t like to let you do much with resources loaded from a different ‘origin’ than the current page. (The origin is defined as the combination of the page’s protocol, hostname, and port. I.e. http://google.com:80).

This is to prevent you from, for example, making requests to your competitors website which cancels any accounts the current user might have (not nice!). Its connection to script tags is somewhat incidental though. The idea is if you apply a handler to the window.onerror event, that handler is provided with some information about the page and script which you perhaps shouldn’t have if you’re loading code from an external site. In secure browsers this info is not included unless you specify crossorigin.

crossorigin isn’t a magical security hack though, what it does is instruct the browser to undergo the normal CORS access check of making an OPTIONS request and checking for Access-Control headers.
