jsPlumb

Question

我是 jsPlumb 的新手，我正在使用 demos。指定目标或源时，我不需要允许连接。我的意思是：当目标是 X - 无法建立连接。

Answer 1

jsPlumb 在建立连接时触发一个事件 connection。

jsPlumb.bind("connection", function(info) {
    if(info.sourceId==='abc'){
      jsPlumb.detach(info.connection);
    }

});

info 是具有以下属性的对象：

connection - the new Connection. you can register listeners on this etc.
sourceId - id of the source element in the Connection
targetId - id of the target element in the Connection
source - the source element in the Connection
target - the target element in the Connection
sourceEndpoint - the source Endpoint in the Connection
targetEndpoint - the targetEndpoint in the Connection
