How to preview an image before and after upload in HTML and JavaScript?
To preview an image before and after upload, you need to try the following code − HTML
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script> <form id = "form1" runat = "server"> <input type ='file' id = "demo" /> <img id = "myid" src = "#" alt = "new image" /> </form>
The following is the jQuery −
function display(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(event) {
$('#myid').attr('src', event.target.result);
}
reader.readAsDataURL(input.files[0]);
}
}
$("#demo").change(function() {
display(this);
});
