如何在 vuetify v-select 的列表和菜单中使用不同的值？

Question

How can I change this example so that in the menu I will get things like "Florida, FL" but in the actual v-select I get "FL" only.

 new Vue({ el: '#app', vuetify: new Vuetify(), data () { return { select: [{ state: 'Florida', abbr: 'FL' }], items: [ { state: 'Florida', abbr: 'FL' }, { state: 'Georgia', abbr: 'GA' }, { state: 'Nebraska', abbr: 'NE' }, { state: 'California', abbr: 'CA' }, { state: 'New York', abbr: 'NY' }, ], } }, })

You don't have to change the settings, only add @change handler to the component, and handle it with a method . Watch for passing the emitted event to your method ( $event ). By passing the values of the emitted event to your method, you can work with the object that was selected (the event actually passes that object to your method).

 new Vue({ el: '#app', vuetify: new Vuetify(), data() { return { select: [{ menuText: 'Florida, FL', state: 'Florida', abbr: 'FL' }], items: [{ state: 'Florida', abbr: 'FL' }, { state: 'Georgia', abbr: 'GA' }, { state: 'Nebraska', abbr: 'NE' }, { state: 'California', abbr: 'CA' }, { state: 'New York', abbr: 'NY' }, ], } }, computed: { menuItems() { return this.items.map(e => { return { menuText: e.state + ', ' + e.abbr, ...e } }) } }, methods: { logValue(e) { this.select = e console.log(e) } } })

 /*.v-select__selection.v-select__selection--comma { display: none; }*/.v-text-field__prefix { color: #242729; }

OTHER HINT

You had an extre Vue script reference in your snippet - I removed it in mine.

EDIT

To have access to the dropdown items, you have to use the item slot v v-select offers. There you can modify the appearance of the items however you want.
