Info

Components 69 Info v-bind is used to dynamically bind one or more attributes, or a component prop to an expression. Since story property is not a string but a javascript object instead of story="..." we use v-bind:story="..." to bind story property with the passed object. The shorthand for v-bind is :, so from now on we are gonna use it like this: :story="...". 6.5 Reusability Let’s take a look again at our Filtered Results example. Assume this time we take the stories variable data from an external API through an http call. The API developers decide to rename plot story property to body. So now, we have to go through our code and make the necessary changes. Info Later in this book we will cover how we can use Vue to make web requests. 1 2 Lets hear some stories! 3 4 Alex's stories 5 6 9 {{ story.writer }} said "{{ story.plot }}" 10 {{ story.writer }} said "{{ story.body }}" 11 12 13 John's stories 14 15 18 {{ story.writer }} said "{{ story.plot }}" 19 {{ story.writer }} said "{{ story.body }}" 20 21
Components 70 22 23 24 What are you looking for? 25 26 27 28 Search results: 29 30 33 {{ story.writer }} said "{{ story.plot }}" 34 {{ story.writer }} said "{{ story.body }}" 35 36 37 38 Note In this particular example syntax highlighting is turned off. As you may have noticed, we had to do the exact same change 3 times and I don’t know about you, but I hate repeating myself. If it doesn’t seem like a big deal for you, imagine that you may use the above code block in 100 places, what would you do then? Fortunately, ‘Vue’ has a solution for that kind of situations, and this solution has a name, Component. Tip Whenever you find yourself repeating a piece of functionality, the most efficient way to deal with it is to create a dedicated Component. Luckily we have created a story Component in the previous example, which displays the writer and the body for a specified story. We can use the custom element inside our HTML and pass each story as we did before with :story tag but this time we will do it inside v-for directive. So our code will be:
