I will be dynamically adding elements to my main index.html using .innerHTML += "<p>example</p>"; However I do not want to store the large html-like string in this .js file, but instead import it from another file example.html
example.html:
<p>example</p>
(It is just a snippet of code and not a standalone html file, but I want to keep the .html extension for linting, autocompletion and general readability)
My attempts:
$(...).load('example.html'): did not work as it replaces of contents of ... with this example instead of appending it
import * from example.html: this and other attempts of importing file failed because of MIME error that text/html cannot be imported
I will be perfectly satisfied with a solution of a method that reads .html as text and returns it as a string (preferably not using AJAX or ES6 as I do not feel confident with them). I would then just use the string in .innerHTML += imported_string; and call it a day.
If I correctly understand what you want to do, you can use FileReader to import the content of a file and convert it to text, for example:
function readFile(event) {
var file = event.target.files[0];
var stream = new FileReader();
stream.onload = function(e) {
var fileContent = e.target.result;
alert(fileContent);
}
stream.readAsText(file);
}
document.getElementById('myFile').addEventListener('change', readFile, false);
<input type="file" accept="html" id="myFile">
The file input is for presentation purposes, you can easily adapt this to your needs.
You should also perform the customary checks, which I ommited for brevity purposes.
Create a fetch request to the file that you want to retrieve. This is, in a basic sense, the same way how a browser would request a html file from the server.
The function below sends a request based on what you input as a file. For example, 'example.html'. It then checks if the request was a success and returns the response as a string. The string can then be appended to your innerHTML.
const getFileAsText = async file => {
const response = await fetch(file);
if (!response.ok) {
throw new Error(`Fetching the HTML file went wrong - ${response.statusText}`);
}
return response.text();
};
You can use it like the example below.
getFileAsText('example.html').then(html => {
document.body.innerHTML += html;
});
