Question

我正在使用JS plumb 1.5.5，基本情况在chrome，IE 10和mozilla上工作正常。但我得到错误：'jsPlumb.Endpoints [...]'为空或不是对象，在IE版本8.0.7600.16385上运行时也是如此。我尝试调试javascript并发现错误正在发生，因为 _jsPlumb.getRenderMode（）未定义。我尝试将renderMode设置为VML和SVG但仍然得到相同的错误。我也必须在IE8上支持这个。抛出错误的示例代码如下所示：

<!DOCTYPE html>

                background-color: #ddddff;
                width: 100px;
            height: 100px;
        }

        #state1 {
            left: 100px;
            top: 100px;
        }

        #state2 {
            left: 250px;
            top: 100px;
        }

        #state3 {
            left: 100px;
            top: 250px;
        }

    <script type="text/javascript">

            jsPlumb.makeSource($('.item'), {
                connector: 'StateMachine'
            });
            jsPlumb.makeTarget($('.item'), {
            anchor: 'Continuous'
            });
        });
    </script>
