Utilizing variables within objects in HTML

Currently, I am working on a tab system using VueJS. Each tab has its own set of properties stored in a list of objects. My goal now is to retrieve these properties within my Vue component.

Below is the Vue code inside my component:

<div>
    <large-card v-bind:path="tabs[currentTab].path"></large-card>
</div>

And here is a snippet of the Vue component (unnecessary code omitted):

export default {
    data () {
        return ({
            tabs: [
                {
                    name: 'Nodes',
                    path: '/nodes/'
                },
                {
                    name: 'Sensors',
                    path: '/sensors/'
                }
            ],
            currentTab: 0
        });
    }
}

It is clear that I am trying to pass the path value of the current tab to my component. In this case, it should receive the value '/nodes/', but it seems to be not functioning as expected. I remember being able to achieve this in Angular by exposing the object as "this" into the scope of an HTML tab, but I can't recall the directive's name...

Thank you for taking the time to read this. Have a wonderful day!

Answer №1

If you want to achieve this, consider using a computed property:

computed: {
    getPath() {
        return this.tabs[this.currentTab].path;
    }
},

Next, link the path to a path prop and transfer it to another child component:

<custom-card v-bind:path="getPath" ></custom-card>
