 <!doctype html>     <html>         <head>             <title>editor</title>             <meta http-equiv="x-ua-compatible" content="ie=9"/>             <meta http-equiv="content-type" content="text/html; charset=utf-8"/>             <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/raphael/2.1.4/raphael-min.js"></script>             <script type="text/javascript" src="<%=request.getcontextpath()%>/connector.js"></script>             <link rel="stylesheet" href="<%=request.getcontextpath()%>/style.css" />              <script type="text/javascript">                 window.onload = function ()         {             var paper = new raphael(raphael("container", "100%", "100%"));             var line = paper.path();             var start = function (x, y) {                 this.ox = this.attr("x");                 this.oy = this.attr("y");                 var line = paper.path("m", this.ox, this.oy);             },                     move = function (dx, dy) {                         this.attr({                             x: this.ox + dx,                             y: this.oy + dy                         });                        paper.path("l",x,y);                     },                     = function () {                         this.animate({                             opacity: 0                         }, 500);                     };                     paper.set(line).drag(move, start, up);         };             </script>         </head>         <body>             <div id="container">                 <div id="header" style="margin-bottom: 0;">                     <h1 id="title">editor</h1>                     <div id="footer"></div>                 </div>             </div>         </body>     </html>

here's live demo: https://jsbin.com/giqufilusu/1/edit?html,output

i don't know why not working. there syntax problem or didn't code correct way. there examples on web of them use jquery + raphael js draw line on mouse events want draw drag() method of raphael. how fix this?

i don't know if got right.

i guess this want achieve?

you defined line variable in scope of start function. adapt line need make available functions. jsbin quick , dirty approach should give hint how can line drawing raphael.
