computed: {
/*fullName: function () {
return this.firstName+' '+this.lastName
}*/
//计算属性一般没有set方法,只读属性
fullName: {
/* set: function (newValue) {
// console.log("------"+newValue);
const names = newValue.split(' ');
this.firstName = name[0]
this.lastName = name[1]
},*/
get: function () {
return this.firstName+' '+this.lastName
}
},
/*fullName: function () {
return this.firstName+' '+this.lastName
}*/
}
})
