Preview image before upload using jQuery

Simply use this code in your project to preview image before upload using JQuery:

<html>
<head>
<style type=”text/css”>.thumb-image{float:left;width:100px;position:relative;padding:5px;}</style>
</head>
<body>
<script src=”https://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js”></script>
<div id=”wrapper” style=”margin-top: 20px;”><input id=”fileUpload” multiple=”multiple” type=”file”/>
<div id=”image-holder”></div>
</div>

<script>
$(document).ready(function() {
$(“#fileUpload”).on(‘change’, function() {
//Get count of selected files
var countFiles = $(this)[0].files.length;
var imgPath = $(this)[0].value;
var extn = imgPath.substring(imgPath.lastIndexOf(‘.’) + 1).toLowerCase();
var image_holder = $(“#image-holder”);
image_holder.empty();
if (extn == “gif” || extn == “png” || extn == “jpg” || extn == “jpeg”) {
if (typeof(FileReader) != “undefined”) {
//loop for each file selected for uploaded.
for (var i = 0; i < countFiles; i++)
{
var reader = new FileReader();
reader.onload = function(e) {
$(“<img />”, {
“src”: e.target.result,
“class”: “thumb-image”
}).appendTo(image_holder);
}
image_holder.show();
reader.readAsDataURL($(this)[0].files[i]);
}
} else {
alert(“This browser does not support FileReader.”);
}
} else {
alert(“Pls select only images”);
}
});
});
</script>
</body>
</html>
