Hi Guys,
Today I will tell you how to upload multiple files using progressbars and webserivces. Below is the code I have used.
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>Courses</title>
<script src="js/jquery-1.11.3.js"></script>
<link href="css/bootstrap.css" rel="stylesheet" />
<style>
.pt10 {
padding-top: 10px;
}
.pb10 {
padding-bottom: 10px;
}
.fileinput-button input {
position: absolute;
top: 0;
right: 0;
margin: 0;
opacity: 0;
-ms-filter: 'alpha(opacity=0)';
direction: ltr;
width: 150px;
cursor: pointer;
}
.fileinput-button {
position: relative;
}
progress::-moz-progress-bar {
background: green;
}
progress::-webkit-progress-value {
background: green;
}
progress {
color: green;
}
</style>
<script src="js/jquery-1.11.3.js"></script>
</head>
