I started using jsPlumb and JQuery, I want to connect draggable elements but if I add the draggable behavior before the connection then the connection does not refresh position.
My code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
".dtd">
<html>
<head>
<title></title>
<style type="text/css">
.window {
background-color: white;
border: 3px solid #346789;
color: black;
font-family: helvetica;
font-size: 0.8em;
height: 12em;
opacity: 0.8;
padding: 0.5em;
position: absolute;
width: 14em;
z-index: 20;
}
</style>
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="jquery-ui.min.js"></script>
<script type="text/javascript" src="jquery.jsPlumb-1.3.2-all-min.js"></script>
</head>
<body>
<div>
<div id="a" class="a window" style="width: 100px;height: 100px;border: solid 1px"></div>
<div id="b" class="b window" style="width: 100px;height: 100px;border: solid 1px;"></div>
</div>
<script type="text/javascript">
$(document).ready(function() {
$(".window").draggable();
var a = $("#a");
var b = $("#b");
jsPlumb.connect({
source:a,
target:b,
connector:["Bezier",68],
endpoints:[
["Dot",{radius:12}],
["Rectangle",{width:20,height:30}]
]
});
});
</script>
</body>

- Hi bill I am facing this problem did you solve this? – The Dead Man Commented Jun 13, 2019 at 20:08

Reset to default 5i wrote jsPlumb.
the reason it doesn't refresh is that it has no way of knowing something is being dragged. instead of calling $(".window").draggable(), you either need to let jsPlumb do that for you when a connection is made, or through this method:
jsPlumb.draggable($(".window"));
the first option will not initialise the dragging for any window that doesn't have a connection. the second one will.
There are few ways to do so - refer to the jsPlumb documentation
,but generally you can use:
- Id of the element
- Array of elements
- Or selector (for example class selector that was mentioned previously:
jsPlumb.draggable($(".window"));
Here is a working example:
<!DOCTYPE html>
<html>
<head>
<title>JS plumb test</title>
<script type="text/javascript" src="http://ajax.googleapis./ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis./ajax/libs/jqueryui/1.8.23/jquery-ui.min.js"></script>
<script type="text/javascript" src="/include/jquery.jsPlumb-1.3.16-all-min.js"></script>
<style>
.window {
background-color: #EEEEEF;
border: 1px solid #346789;
border-radius: 0.5em;
box-shadow: 2px 2px 19px #AAAAAA;
color: black;
height: 5em;
position: absolute;
width: 5em;
cursor: pointer;
}
</style>
<script>
jsPlumb.ready(function () {
// three ways to do this - an id, a list of ids, or a selector (note the two different types of selectors shown here...anything that is valid jquery will work of course)
//jsPlumb.draggable("container0");
//jsPlumb.draggable(["container0", "container1"]);
jsPlumb.draggable($(".window"));
//perform operation only after DOM is loaded
var e0 = jsPlumb.addEndpoint("container0"),
e1 = jsPlumb.addEndpoint("container1");
jsPlumb.connect({ source: e0, target: e1 });
});
</script>
</head>
<body >
<div class="window" style="left: 20px" id="container0">
</div>
<div class="window" style="left: 200px" id="container1">
</div>
</body>
</html>
