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). The response is always decoded using UTF-8.
Syntax
response.text().then(function (text) { // do something with the text response });
Parameters
None.
Return value
A Promise that resolves with a USVString
.
Example
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.
let myArticle = document.querySelector('article'); let myLinks = document.querySelectorAll('ul a'); for(let i = 0; i <= myLinks.length-1; i++) { myLinks[i].onclick = function(e) { e.preventDefault(); let linkData = e.target.getAttribute('data-page'); getData(linkData); } }; function getData(pageId) { console.log(pageId); var myRequest = new Request(pageId + '.txt'); fetch(myRequest).then(function(response) { return response.text().then(function(text) { myArticle.innerHTML = text; }); }); }
