Image Upload with preview and Delete option – Javascript / Jquery
I have code below that runs perfectly and uploads multiple images.
This is the html and jQuery code:
<div class="field" align="left">
<span>
<h3>Upload your images</h3>
<input type="file" id="files" name="files[]" multiple />
</span>
</div>
The script is as below:
<style>
input[type="file"] {
display:block;
}
.imageThumb {
max-height: 75px;
border: 2px solid;
margin: 10px 10px 0 0;
padding: 1px;
}
</style>
<script type="text/javascript">
$(document).ready(function() {
if(window.File && window.FileList && window.FileReader) {
$("#files").on("change",function(e) {
var files = e.target.files ,
filesLength = files.length ;
for (var i = 0; i < filesLength ; i++) {
var f = files[i]
var fileReader = new FileReader();
fileReader.onload = (function(e) {
var file = e.target;
$("<img></img>",{
class : "imageThumb",
src : e.target.result,
title : file.name
}).insertAfter("#files");
});
fileReader.readAsDataURL(f);
}
});
} else { alert("Your browser doesn't support to File API") }
});
</script>
The code adds multiple images and shows previews of the images too. But now I want that when a user clicks on some button, lets say delete on every image uploaded, it should be removed. Not hidden.
Any help to this will be appreciated!
Try adding this : .click(function(){$(this).remove();});. It will remove the image by clicking it.
EDIT Improved version included.
EDIT 2 Since people keep asking, please see this answer on manually deleting a file from a FileList (spoiler: it’s not possible…).
$(document).ready(function() {
if (window.File && window.FileList && window.FileReader) {
$("#files").on("change", function(e) {
var files = e.target.files,
filesLength = files.length;
for (var i = 0; i < filesLength; i++) {
var f = files[i]
var fileReader = new FileReader();
fileReader.onload = (function(e) {
var file = e.target;
$("<span class=\"pip\">" +
"<img class=\"imageThumb\" src=\"" + e.target.result + "\" title=\"" + file.name + "\"/>" +
"<br/><span class=\"remove\">Remove image</span>" +
"</span>").insertAfter("#files");
$(".remove").click(function(){
$(this).parent(".pip").remove();
});
// Old code here
/*$("<img></img>", {
class: "imageThumb",
src: e.target.result,
title: file.name + " | Click to remove"
}).insertAfter("#files").click(function(){$(this).remove();});*/
});
fileReader.readAsDataURL(f);
}
});
} else {
alert("Your browser doesn't support to File API")
}
});input[type="file"] {
display: block;
}
.imageThumb {
max-height: 75px;
border: 2px solid;
padding: 1px;
cursor: pointer;
}
.pip {
display: inline-block;
margin: 10px 10px 0 0;
}
.remove {
display: block;
background: #444;
border: 1px solid black;
color: white;
text-align: center;
cursor: pointer;
}
.remove:hover {
background: white;
color: black;
}<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="field" align="left">
<h3>Upload your images</h3>
<input type="file" id="files" name="files[]" multiple />
</div>Use this for remove files values and file preview
$(".remove").click(function(){
$(this).parent(".pip").remove();
$('#files').val("");
});`
