[Vuejs]-How to obtain the id (or any other attribute) of the component clicked in Vue template?

You can access the element clicked from the current event.

The code would look something like this

<a v-on:click="myFunction($event, 'param')">Click me</a>

// in your component
methods: {
    myFunction: function(event, param) {
        console.log(event.target);
    }
}
