How do you keep the text file in line?

[Mystic]

I'm trying to get a line from the text file, the console's getting out of the way, but I can't keep it.

uploadString( e ) {
      var file = e.target.files[0];
      var reader = new FileReader();
      reader.onload = function() {
        console.log(reader.result);
        this.textToChange=reader.result
      };
  reader.readAsText(file);
},

You've lost context. Look what turns this into a processor onload.

example for test.txt

const Hello = Vue.extend({
  template: `
    <div>
      <input type="file" @input="uploadString"/> 
      <div v-html="msg"></div>
    </div>
  `,
  data() {
    return {
      msg: 'Hello!'
    }
  },
  methods: {
    saveText (e) {
      console.log(e.currentTarget, e.target);
      this.msg = e.target.result
    },
    uploadString( e ) {
      var file = e.target.files[0];
      var reader = new FileReader();
      reader.onload = this.saveText;
      reader.readAsText(file);
    },
  }
})
new Vue({

el: '#app',

components: {

Hello

}

})

<div id="app">

</div>
