Clearing form data after submitting in Laravel using axiosIn Laravel, utilizing

When working on my Laravel app, I encountered an issue while submitting a form using Vue and Axios. Despite my attempts to clear the input field after submission, it doesn't seem to work.

HTML:

<form method="post" enctype="multipart/form-data" v-on:submit.prevent="addPost">
  <textarea id="post_area" v-model="content"></textarea>
  .....
</form>

JS:

const app = new Vue({
el: '#app',
data: {
  content: '',
  posts: []
},

......

.then(function (response) {
   if(response.status===200) {
      //reload posts
      app.posts = response.data;
      this.content = '';
   }
})

Despite efforts, the input field remains uncleared after submission.

Answer №1

this does not refer to the Vue instance within your Promise's success callback.

Try using an arrow function instead. Arrow functions bind the value of this lexically.

const app = new Vue({
el: '#app',
data: {
  content: '',
  posts: []
},

......

.then( (response) => {
   if(response.status===200) {
      //reload posts
      app.posts = response.data;
      this.content = '';
   }
})

Alternatively, you can create a local variable that points to the correct Vue instance and use it to access your data property like this:

methods:{
    addPost(){
        var vm = this;

        //.....axios post
         .then( (response) => {
            if(response.status===200) {
                //reload posts
                app.posts = response.data;
                vm.content = '';
            }
        }) 

    }
}
