I'm making a html editor but the problem is that when someone needs to view an html file i don't know how to display the text from the file.
<input type="file" onchange="previewFile()"><br>
<p id="txt1" src="blank.html"></p>
<script>
function previewFile() {
const preview = document.getElementById('txt1');
const file = document.querySelector('input[type=file]').files[0];
const reader = new FileReader();
reader.addEventListener("load", function () {
// reads image file to a blob string
preview.src = window.URL.createObjectURL(file);
}, false);
if (file) {
reader.readAsDataURL(file);
}
}
</script>
I used this script to read a file and display it by changing the paragraph src to a blob link, but looks like the paragraph dosn't get the text by a html text link using src. Is there a way to do it?
The paragraph does not have src attribute, You need to use either innerText or innerHTML to display the content.
function previewFile() {
const content = document.querySelector('.content');
const [file] = document.querySelector('input[type=file]').files;
const reader = new FileReader();
reader.addEventListener("load", () => {
// this will then display a text file
content.innerText = reader.result;
}, false);
if (file) {
reader.readAsText(file);
}
}<input type="file" onchange="previewFile()"><br>
<p class="content"></p>Collected from the Internet
