Another way to approach the same problem is to use Axios for sending the AJAX request. If you need to brush up on what Axios is, take a look at the Sending basic AJAX requests with Axios recipe.
The code for the submit method will become as follows (remember to add Axios as a dependency):
submit () { axios.post('http://jsonplaceholder.typicode.com/posts', { title: this.title, body: this.body, userId: this.userId }).then(response => { this.response = JSON.stringify(response,null,' ') }).catch(error => { this.response = 'Error: ' + error.response.status }) }
This code is perfectly equivalent, but it's much more expressive and concise than using native browser objects.
