"When the value is false, use the Vue binding to apply a specific

My challenge involves managing a website that is designed to receive boolean values and store them in an array where the key represents the ID and the value represents the boolean.

For example:

policiesActive[
"2"   => false,
"3"   => false]

The website includes a list-group with three items.

For instance:

.list-group
    a.list-group-item.list-group-item-action.flex-column.align-items-start(v-for='firewallPolicy in activeFirewall.policies', href='', @click.prevent='setPolicyActive(activeFirewall.id, firewallPolicy.id)', v-bind:class='{ active: policiesActive[firewallPolicy.id] }')
        .d-flex.w-100.justify-content-between
        h5.mb-1 {{firewallPolicy.name}}
        p.mb-1 {{firewallPolicy.description}}

Each list-group item needs to be checked to determine if it is active or not. The first two are compared against policiesActive, while the third one should be true only if both values in policiesActive are false.

I am struggling to figure out how to handle this last scenario where both values are false. Can you provide any guidance?

Answer №1

To find the appropriate class, one simple method is to compute it within a function. Below is an example of how this can be done:

<a
    v-for="(policy, index) in policies"
    class="list-group-item"
    :class="getItemClass(policy, index)"
    href="..."
>
    ...
</a>

Subsequently, define the following method:

methods: {
    getItemClass(policy, index) {
        let itemClass = "";
        // ... add whatever logic you need to determine the classname
        return itemClass;
    }
}
