TypeError: d is not a function in jsPlumb

TypeError: d is not a function in jsPlumb

我正在使用 jsplumb

<script type ="text/javascript" src= "http://theanalyticstreedemo.cloudapp.net:81/NanoClientApplication/js/JsPlumb/jquery.jsPlumb-1.4.1-all-min.js"></script>
<script type ="text/javascript" src= "http://localhost:8082/NanoClientApplication/newWebApp/assets/js/jquery-ui.min.js"></script>

jsPlumb.makeSource($(e), {
   anchor:"Continuous",
   endpoint:["Rectangle", { width:40, height:20 }],
   maxConnections:3
});

动态建立连接时出现 TypeError: d is not a function 错误

我找到了解决办法, jquery-ui.min.js加载多次
