Populating options for select using v-for VueJS after handling load data event
up vote

I have this VueJS application written using Typescript. I'm using Axios to get data from my database. This works well and the result I get is an array which is what I was expecting. When I do console.log on this array I can see that it's the correct result.
However, when I try to loop through this array to create the options for my select drop down I get a blank list. Why isn't the result coming up even though the variable I'm looping through is an array?
Edit: I've added a picture here showing the Axios result (response.data)
export default class EditRoute extends Vue {
result: any;
selectedRoute: string;
constructor(){
super();
this.selectedRoute = "";
this.result = ;
}
loadData() {
axios.get('http://localhost:8080/routes')
.then(response => (this.result = response.data));
}
}
<select name="routeSelect" v-model="selectedRoute">
<option v-for="routes in result" v-bind:key="routes.name" v-bind:value="routes.name"> {{ routes.name }} </option>
</select>
<button @click="loadData">Load data</button>

Since your result is an object which is containing one item, that item is an array called routes in this case you should loop through result.routes like so :
<option v-for="routes in result.routes" v-bind:key="routes.name" v-bind:value="routes.name"> {{ routes.name }} </option>
Extra Example :
new Vue({
el: '#app',
data: function() {
return {
selectedUser: '',
users: ,
}
},
mounted: function() {
// this.loadData();
// this.timer = setInterval(this.loadData, 4000);
},
methods: {
loadData: function() {
axios.get('https://jsonplaceholder.typicode.com/users').then(response => {
this.users = response.data;
}).catch(e => {
})
}
}
