javascript - Can I pass parameters in computed properties in Vue.Js -

is possible pass parameter in computed properties in vue.js. can see when having getters/setter using computed, can take parameter , assign variable. here documentation:

// ... computed: {   fullname: {     // getter     get: function () {       return this.firstname + ' ' + this.lastname     },     // setter     set: function (newvalue) {       var names = newvalue.split(' ')       this.firstname = names[0]       this.lastname = names[names.length - 1]     }   } } // ... 

is possible:

// ... computed: {   fullname: function (salut) {       return salut + ' ' + this.firstname + ' ' + this.lastname       } } // ... 

where computed property takes argument , returns desired output. when try this, getting error:

vue.common.js:2250 uncaught typeerror: fullname not function(…)

should using methods such cases?

you should use methods:

<span>{{ fullname('hi') }}</span>  methods: {   fullname: function (salut) {       return salut + ' ' + this.firstname + ' ' + this.lastname       } } 

p.s. difference between computed property , method computed properties cached , change when dependencies change - that's why can't pass parameters there. methods evaluated every time call them.
