Can you trigger some type of event with drag and drop boxes?
Question
I'm trying to develop a small site where user can drag and drop pictures. So when user drags a particular picture to the box it would return some kind of a result in the form of text like details about that picture...
This is the current code that I'm using to accomplish drag and drop, but I can't figure out how to add functionality that I described above:
<!DOCTYPE HTML>
<html>
<head>
<meta charset ="utf-8">
<style type="text/css">
#dragBox {width:336px;height:221px;padding:10px;border:1px solid #aaaaaa;}
</style>
<script>
function allowDrop(ev)
{
ev.preventDefault();
}
function drag(ev)
{
ev.dataTransfer.setData("Text",ev.target.id);
}
function drop(ev)
{
ev.preventDefault();
var data=ev.dataTransfer.getData("Text");
ev.target.appendChild(document.getElementById(data));
}
</script>
</head>
<body bgcolor="#333333">
<div div align="center">
<img id="drag1" src="foodOne.jpg" draggable="true" ondragstart="drag(event)" width="336" height="221">
<div id="dragBox" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
</div>
</body>
</html>

A drop event can have a files property. You can read the files with JavaScript. The common approach is to send it to the server which can then send the information back, like a path to a thumbnail.
There are a lot of scripts readily available already, just Google/Bing.
