This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the spec changes.

The text() method of the Body mixin takes a Response stream and reads it to completion. It returns a promise that resolves with a USVString object (text).


response.text().then(function (text) {
  // do something with the text response 




A promise that resolves with a USVString.


In our fetch text example (run fetch text live), we have an <article> element and three links (stored in the myLinks array.) First, we loop through all of these and give each one an onclick event handler so that the getData() function is run — with the link's data-page identifier passed to it as an argument — when one of the links is clicked.

When getData() is run, we create a new request using the Request() constructor, then use it to fetch a specific .txt file. When the fetch is successful, we read a USVString (text) object out of the response using text(), then set the innerHTML of the <article> element equal to the text object.

var myArticle = document.querySelector('article');
var myLinks = document.querySelectorAll('ul a');

for(i = 0; i <= myLinks.length-1; i++) {
  myLinks[i].onclick = function(e) {
    var linkData ='data-page');
function getData(pageId) {
  var myRequest = new Request(pageId + '.txt');
  fetch(myRequest).then(function(response) {
    return response.text().then(function(text) {
      myArticle.innerHTML = text;
