There are times you need to change an element’s CSS classes at runtime. But when changing classes, it’s sometimes best to apply style details conditionally. For example, imagine your view has a pager. Pagers are often used to navigate larger sets of items. When navigating, it can be helpful to show the user the page they’re currently on. The style of the item is conditionally set, based on the current page that’s being viewed.

A pager in this case may look something like this:

In this example, there are five pages. Only one of these pages is selected at a time. If you built this pager with Bootstrap, the selected page would have a CSS class named active applied. You’d want this class applied only if the page was the currently viewed page. In other words, you’d want to conditionally apply the active CSS class. Luckily, Vue provides a way to conditionally apply a CSS class to an element, which I’m going to demonstrate in this article.

To conditionally apply a CSS class at runtime, you can bind to a JavaScript object. To successfully complete this task, you must complete two steps. First, you must ensure that your CSS class is defined. Then, you create the class bindings in your template. I’m going to explain each of these steps in detail in the rest of this article.

Step 1: Define Your CSS Classes

Imagine, for a moment, that the five page items shown in the image above were defined using the following HTML:

<div id=”myApp”>
<nav aria-label=”Page navigation example”>
<ul class=”pagination”>
<li class=”page-item”><a class=”page-link” href=”#”>1</a></li>
<li class=”page-item”><a class=”page-link” href=”#”>2</a></li>
<li class=”page-item active”><a class=”page-link” href=”#”>3</a></li>
<li class=”page-item”><a class=”page-link” href=”#”>4</a></li>
<li class=”page-item”><a class=”page-link” href=”#”>5</a></li>
</ul>
</nav>
</div>

Notice that each page in this code snippet has a list-item element (<li …). That element references the page-item CSS class. In the code for this article, this class is defined in the Bootstrap CSS framework. However, if it weren’t defined there, it would be your responsibility to ensure that it was defined somewhere. The second CSS class is the one that’s most relevant to this article, though.

The active CSS class is used to identify the currently selected page. For this article, this CSS class is also defined in the Bootstrap CSS. As shown in the snippet above, the active class is only used in the third list item element. As you can probably guess, this is the CSS class that you want to apply conditionally. To do that, you need to add a JavaScript object.

Graphic Design for Adidas Predator by Gordon Reid

abduzeedoMar 25, 2019

Gordon Reid shared a beautiful graphic design project for Adidas and one of their most iconic soccer (football) boots in history, The Predator. Adidas London wanted to create a range of new print, digital and social ads to mark the relaunch of this historic boot along with the launch of two new boots, the X and Nemeziz.

Gordon worked with the strapline for each boot to create illustrated assets for each boot. Each created to compliment the culture, history and design of each of the boots. For Instance, the Predator played on more of a retro, bold and graphic feel, whereas the X artwork played on the enhanced speed element and Nemeziz was all about being agile. Each artwork was brought to life using a bold color palette and strong graphical elements that could be used throughout the advertising.

For those starting out learning Vue, there’s a bit of confusion over the difference between methods, computed properties and watchers.

Even though it’s often possible to use each of them to accomplish more or less the same thing, it’s important to know where each outshines the others.

In this quick tip, we’ll look at these three important aspects of a Vue application and their use cases. We’ll do this by building the same search component using each of these three approaches.

Methods

A method is more or less what you’d expect — a function that’s a property of an object. You use methods to react to events which happen in the DOM, or you can call them from elsewhere within your component — for example, from within a computed property or watcher. Methods are used to group common functionality — for example, to handle a form submission, or to build a reusable feature such as making an Ajax request.

You create a method in a Vue instance, inside the methods object:

new Vue({
el: “#app”,
methods: {
handleSubmit() {}
}
})

And when you want to make use of it in your template, you do something like this:

<div id=”app”>
<button @click=”handleSubmit”>
Submit
</button>
</div>

We use the v-on directive to attach the event handler to our DOM element, which can also be abbreviated to an @ sign.

The handleSubmit method will now get called each time the button is clicked. For instances when you want to pass an argument that will be needed in the body of the method, you can do this:

<div id=”app”>
<button @click=”handleSubmit(event)”>
Submit
</button>
</div>

Here we’re passing an event object which, for example, would allow us to prevent the browser’s default action in the case of a form submission.

However, as we’re using a directive to attach the event, we can make use of a modifier to achieve the same thing more elegantly: @click.stop=”handleSubmit”.

Now let’s see an example of using a method to filter a list of data in an array.

In the demo, we want to render a list of data and a search box. The data rendered changes whenever a user enters a value in the search box. The template will look like this:

<div id=”app”>
<h2>Language Search</h2>

<div class=”form-group”>
<input
type=”text”
v-model=”input”
@keyup=”handleSearch”
placeholder=”Enter language”
class=”form-control”
/>
</div>

<ul v-for=”(item, index) in languages” class=”list-group”>
<li class=”list-group-item” :key=”item”>{{ item }}</li>
</ul>
</div>

As you can see, we’re referencing a handleSearch method, which is called every time the user types something into our search field. We need to create the method and data:

new Vue({
el: ‘#app’,
data() {
return {
input: ”,
languages: []
}
},
methods: {
handleSearch() {
this.languages = [
‘JavaScript’,
‘Ruby’,
‘Scala’,
‘Python’,
‘Java’,
‘Kotlin’,
‘Elixir’
].filter(item => item.toLowerCase().includes(this.input.toLowerCase()))
}
},
created() { this.handleSearch() }
})

The handleSearch method uses the value of the input field to update the items that are listed. One thing to note is that within the methods object, there’s no need to reference the method with this.handleSearch (as you’d have to do in React).
