How to pass a dynamic function name to the click event in Vue Js

@click="[fuctionName]($event, index)"

Example:

<button v-for="(button,index) in items" @click="[fuctionNames[index]]($event, index)" > // consider fuctionNames array of Function Names.

To use dynamic function call it is suggested to have a helper function that receives the function name and call the corresponding function.

handle_function_call(function_name) {
    this[function_name]()
},

And from template when iterating over items you can call that function by passing the function name like

<button v-for="button of items"
       :key="button.id" 
       @click="handle_function_call(button.fn_name)" //=> note here
>
  {{ button.text }}
</button>
