Guidelines for executing a Vue directive when the page is initially loaded

I am iterating through an array of objects containing map svg paths and locales, and I want to execute a function on load. The function needs to take the locale keys from the paths array as a parameter and perform some operation:

<p v-for="(country, locale) in paths" @load="myFunction(locale)">log {{locale}}</p>

However, the @load directive does not seem to work. Oddly enough, when using the @click directive instead, it works as expected:

<p v-for="(country, locale) in paths" @click="myFunction(locale)">log {{locale}}</p>

This is the function being called:

const myFunction = (locale) => {
    console.log(locale)
}

How can I get the @load directive to function properly?

It seems like using directives may not be the best approach for this task. Since all related variables are already in one array, why not simply iterate through the array within the mounted method? For example:

mounted() {
  this.paths.forEach((path) => {
    this.myFunction(path.locale);
  })
}

This logic could also be implemented within the created hook.

By the way, just to clarify, the usage of @click and @load in your code does not involve directives. These are events that you are registering listeners to. The click event works as expected, but the load event is not triggered because the element does not actually fire that event. It's possible there was some confusion about what a directive actually is.
