I need To find out the file type from a url image located on my server without checking the extension, but I'm not sure how to do that without putting the image into an "input" like this:
<input type="file" id="upload_file" accept="image/*|audio/*|video/*"/>
<input type="submit" onclick="sumbit()"/>
<script type="text/javascript">
function sumbit(){
var file_Element = document.getElementById("upload_file")
alert(file_Element.files[0].type);
//alert: image/png
}
<script>
I understand that ".type" only work with a file object, so how do I turn the url image into an object like this image of google's logo: https://www.google.ca/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png. Do I need to use a ajax/flilereader? if so, how?
