Vuejs does not render data from ajax - vuejs2

Question

I use jQuery ajax to request api and get the respone, but the data cannot be rendered. Does someone know how to fix this problem?
var app = new Vue({
//router,
data: {
people: null
},
created: function() {
$.ajax({
url: 'test.php',
}).done(function(res){
console.log(res);
this.people = JSON.parse(res);
//console.log('124234234523');
//console.log(this.people.name);
});
}
}).$mount('#app');
<div id="app">
<ol>
<li v-for="person in people">
{{ person.name }}
</li>
</ol>
</div>
Code use vue router:
While I use Vue router, even I use arrow function. The template cannot be render by Vue. Whether do I misuse Vue router?
// Listing people component
var PeopleListing = Vue.extend({
template: '#people-listing-template',
data: function() {
return {
people: this.$parent.people
}
}
});
// Create the router
var router = new VueRouter({
mode: 'hash',
base: window.location.href,
routes: [
{path: '#/', component: PeopleListing},
{name: 'person', path: '/:id', component: PersonDetail }
]
});
var app = new Vue({
router,
data: {
people: null
},
created: function() {
$.ajax({
url: 'test.php',
}).done((res) =>{
//console.log(res);
this.people = JSON.parse(res);
//console.log('124234234523');
//console.log(this.people.name);
});
}
}).$mount('#app');
<div id="app">
<router-view class="view"></router-view>
</div>
<template id="people-listing-template">
<ul>
<li v-for="person in people">
{{ person.name }}
<router-link :to="{ name: 'person', params: { id: person.guid }}">View Details</router-link>
</li>
</ul>
</template>

Answer 1

Scope of this is creating issue, use arrow function like following:
var app = new Vue({
//router,
data: {
people: null
},
created: function() {
$.ajax({
url: 'test.php',
}).done((res) => {
console.log(res);
this.people = JSON.parse(res);
//console.log('124234234523');
//console.log(this.people.name);
});
}
}).$mount('#app');
