Video: Modifying elements as text

Although you can modify the content of notes as HTML text with the inner HTML property, there's a few other ways of doing it. However there's some really big browser issues here. Let's take a look anyways. You can use the innerText property to get just the text of the node. However you have to use textContent if you're using Firefox. That means that if you want to access just the text of a node, you're going to have to do something like this in JavaScript. If the text exists within the inner text property, then you can set your text to that.

The Document Object Model (DOM) is at the core of every HTML page. In order to develop dynamic HTML pages, a front-end developer needs to understand how JavaScript connects to and controls the DOM, allowing you to create, modify, delete, and edit existing page content. This course focuses on helping you understand the DOM elements, and shows the different ways JavaScript gives you access to them and makes it easier to work with the DOM. Author Ray Villalobos covers navigating the DOM, selecting elements, modifying HTML attributes, editing nodes, and much more.

Topics include:
  • What is the DOM?
  • Choosing and isolating elements
  • Traversing up and down DOM nodes
  • Changing HTML attributes
  • Modifying elements as text
  • Creating and appending nodes
  • Cloning and removing nodes
  • Adding a bubbling event listener
  • Adding and resizing images
  • Handling clicks

Modifying elements as text

Although you can modify the content of notes as HTML text with the inner HTML property, there's a few other ways of doing it. However there's some really big browser issues here. Let's take a look anyways. You can use the innerText property to get just the text of the node. However you have to use textContent if you're using Firefox. That means that if you want to access just the text of a node, you're going to have to do something like this in JavaScript. If the text exists within the inner text property, then you can set your text to that.

Otherwise you'll have to use the Firefox version. So let's take a look at this in the dom. We'll start by getting an element from the dom, we'll place it in a variable called my node. So right now we're targeting this section right here called about the event. If you want to, you can click on the magnifying glass and click on that headline. Let me go ahead and hit enter and test out my node. And sure enough, it has the whole article, now if we do a direct version of this, we can see the different properties available to that node.

Right next to the innerHTML property, we have a property called innerText. If you look at it carefully, you'll see that it's the same text as innerHTML, without any of the HTML tags. So if I type in my node, that innerText, and hit enter, you'll see that it's just the text of that node. So I imagine that if I wanted to get just the text of some content, this might be a really convenient way to do it. This is a read and write property as well, so you can set it, if you want to. I'm not really sure how useful that is because it'll wipe out any sort of formatting or syntax you worked really hard to put in there. Also this version, as I mentioned, is not supported by Firefox. Firefox has a similar property you can use called Text Content. But, unfortunately, Text Content is supported by everything except for Internet Explorer.

So if you want to use these, you'll have to create some if-then statements. A check, which property, the current browser supports. This is the type of thing (LAUGH) that can give you a headache as a web developer, so I would probably stay away from these.
