问题
I am very new to Vue js and I am now trying to output all the users in a table by fetching them with an ajax call. I get the users with no issue but then when I try to set the data.user with the new data I get an error saying the property or method users is not defined. This is my user list components:
<template>
<div class="container">
<div class="row">
<div class="col-md-8 col-md-offset-2">
<div class="panel panel-default">
<div class="panel-heading">List of users</div>
<div class="panel-body">
<table class="table">
<thead>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Email</th>
</tr>
</thead>
<tbody>
<tr v-for="user in users">
<td>user.name</td>
<td>user.lastaname</td>
<td>user.email</td>
</tr>
</tbody>
</table>
</div>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
data: function () {
return {
users: []
}
},
mounted() {
axios.get('/users')
.then(function (response) {
console.log(response.data);
})
.catch(function (error) {
console.log(error.message);
});
},
}
</script>

Try this
<script>
export default {
data: function () {
return {
users: []
}
},
methods: {
getUsers: function() {
var app = this;
axios.get('/users')
.then(function (response) {
app.users = response.data;
})
.catch(function (error) {
console.log(error.message);
});
}
},
created() {
this.getUsers();
},
}
ES6 Syntax
getUsers() {
axios.get('/users')
.then((response) => this.users = response.data)
.catch((error) => console.log(error.message))
}
