How to make behavior definition in vuejs based on class?

Question

Vue.js

Hello.
I continue to master Vue.JS, so the question may be noob and incorrect :)
I have a form that has input fields. On @click (let's say) for each field, I have a specific action. Now the task is to hang one more handler on onfocus. To do this, I will have to manually add @focus="onFocus". But what if there are a lot of input fields? It's inconvenient and inefficient. Using good old jQuery (and vanilla javascript as well) I could hang a handler on all these elements in one line. Doesn't it work with Vue?
Thank you.
