Exploring Vue Component Features through Conditional Display

I am working with a vue component called <PlanView/>. In my code, I am rendering this component conditionally:

<div v-if="show_plan" id="mainplan">
  <PlanView/>
</div>
<div class="icon" v-else>
  <font-awesome-icon icon="fa-solid fa-angles-right" @click="openPlan"/>
</div>
openPlan() {
    this.show_plan = true;
},

However, I want the functionality to be triggered even when the component is not rendered. Can you please provide guidance on how I can achieve that? Thank you in advance.

Answer №1

To ensure that the component is rendered but not displayed, you can manipulate the visibility of the template within the component instead of hiding the entire component.

Include a prop in PlanView to determine whether the template should be rendered or not

<PlanView :showPlan="show_plan"/>

Access the prop within the PlanView component like this:

defineProps({
    showPlan: {
        type: Boolean,
        required: false,
        default: false
    }
})

Render the PlanView template only if the prop condition is met. In this case, the template will appear as follows:

<template>
    <!-- Container element -->
    <div v-if="showPlan"> 
        <!-- The rest of your template goes here -->
    </div>
</template>

Alternatively

You can simply use v-show on the wrapper element so that it loads but remains hidden on the UI when the condition is false

<PlanView v-show="show_plan"/>

Answer №2

To achieve the desired outcome, consider utilizing v-show in place of v-if, as suggested by @Nitheesh.

<div v-show="show_plan" id="mainplan">
  <PlanView/>
</div>
<div v-show="!show_plan" class="icon">
  <font-awesome-icon icon="fa-solid fa-angles-right" @click="openPlan"/>
</div>

It's important to clarify if this approach aligns with your concept of "calling the functionality."
