I have the following code not working. I want the image to appear in a swal (Sweet Alert) when the input is changed, but I don't know what's not working. I get the following error on console:
Failed to execute'readAsDataURL' on 'FileReader': parameter 1 is not type 'Blob'
INPUT
<input id=input type=file style=display:none; onchange=muda()>
Script
<script>
function muda(){
var thefile = document.getElementById('input');
var reader = new FileReader();
reader.onloadend = function(){
var imagem = reader.result;
}
if(thefile){
reader.readAsDataURL(thefile);
}
swal({
title: Esta é a imagem que pretende inserir?,
text: <img src='+imagem+' style='width:150px;'>,
html:true,
});
}
</script>
UPDATE
With adaneo response, I managed to read the file name adding .files[0];
but I don't know how to get the image path now, I tried to put a variable named image as you can see in the code but it turns undefined
