Angularjs 在angular.js指令中使用JSPlumb
我试图将jsPlumb与AngularJS一起使用，但遇到了一些问题。我从github的jsplumb ng示例开始，试图修改jsplumb参数，以模仿jsplumb站点的statemachine演示。JSPlumbNG方法创建一个jsPlumbCanvas指令，它包含jsPlumbNodes。作为起点，我尝试从statemachine演示中放置一些静态节点，然后添加两个由angular控制器控制的节点。演示节点正确放置在画布上，并创建连接。角度节点被创建，jsPlumb在makeTarget方法中遇到问题，并将消息打印到控制台 TypeError:无法设置未定义的{stack:（…）的属性“\u jsPlumbTarget”，消息：“无法设置未定义的”}的属性“\u jsPlumbTarget” 我将非常感谢任何建议，以继续前进 提前道歉，因为我没有足够的声誉来发布问题的图片，这是我一直在回避的事实 i、 imgur.com/Ao4qzm9.pngAngularjs 在angular.js指令中使用JSPlumb,angularjs,jsplumb,Angularjs,Jsplumb,我试图将jsPlumb与AngularJS一起使用，但遇到了一些问题。我从github的jsplumb ng示例开始，试图修改jsplumb参数，以模仿jsplumb站点的statemachine演示。JSPlumbNG方法创建一个jsPlumbCanvas指令，它包含jsPlumbNodes。作为起点，我尝试从statemachine演示中放置一些静态节点，然后添加两个由angular控制器控制的节点。演示节点正确放置在画布上，并创建连接。角度节点被创建，jsPlumb在makeTarget方
