As you do so, you'll notice all the navigations happening inside the, not its parent window. go to the courses page, or maybe our blog page). In the link above, try navigating our landing page inside the (for e.g. It's just a simple loading up our landing page. The containing webpage where the element exists is called the embedding webpage.Īnd this is it for the basic terminology used while discussing about iframes. So in that sense, we have parent windows, child windows, and top-level windows.Īn embeds a webpage into an existing webpage often called the embedded page. Sometimes these terms are also referred to with the word 'window'. The top-level browsing context is one without any parent, hence the 'top-level', and it's almost always the main browser tab/window. Similarly, C is called the child browsing context of P. a tab/window can contain an, which itself denotes a new browsing context.Ī browsing context P that contains another browsing context C is called the parent browsing context of C. A simple exampleīecause a browsing context has a separate allocation of its resources, it's a good idea to keep s (which create browsing contexts) to a minimum in order to conserve the memory of the underlying machine.īrowsing contexts can contain browsing contexts within them. , however, still remains an integral component of many modern-day websites. and were deprecated in HTML5 due to certain usability and accessbility issues, which we'll discuss later on in this chapter. And that's where the blog leverages the element.Īnyways, moving on, was introduced under the larger idea of 'frames', as a way to embed documents within documents, in HTML4, along with its friends and. In this case, the blog can simply embed a third-party's web application, meant to read code and produce its output in situ. It would be too early to explain all that technical jaron at this stage.Īs a simple example of an, one that you would've probably already witnessed before, suppose a blog has to embed a code snippet along with a program that can run that code (sometimes on another server) and show the response/output live, something like Codepen or JSFiddle. In some cases, you might have received a pre-compiled embed script code for an iframe from a service you want to add to your website, an Eventbrite ticket page.The fact that certain things are easier with s will become much clearer to you once you become a complete developer, knowing how to develop custom video player, ad libraries, and interactive utility apps, using JavaScript and other web technologies. Here's an example: var iframe = document.getElementById( "myiframe") Once you have access to the document object, you can use the innerHTML property to add your code. To do this, you'll need to use the contentWindow property of the iframe element to access the iframe's document object. This is a great option if you need to add some dynamic functionality to your iframe, such as a form validation script. The first method is to use JavaScript to inject code into an iframe. There are a few different ways to do this, but we'll focus on two of the most popular methods: JavaScript and HTML attributes.

Now, let's talk about how to inject code or prefill fields in an iframe. Essentially, it's a window within a window, and it's a great way to add extra functionality to your website without cluttering up your main page.

Injecting code or prefilling fields in an iframe can be a tricky task, but with a little bit of know-how, it's definitely doable.
