jsPlumb错误：<svg>属性width =＆＃34; -Infinity＆＃34;的值无效

Question

我动态创建了一个jsPlump图

jsPlumb.ready(function(){
    jsPlumb.setContainer('row');

    var endPointLeft = {
      maxConnections : 1,
      onMaxConnections: function(info, e){
        alert('Max. 1');
      },
      connector: ['Straight'],
      anchor: 'Right',
      endpoint: 'Dot',
      isSource: true,
      isTarget: true
    };

    var endPointRight = {
      maxConnections : 1,
      onMaxConnections: function(info, e){
        alert('Max. 1');
      },
      connector: ['Straight'],
      anchor: 'Left',
      endpoint: 'Dot',
      isSource: true,
      isTarget: true
    };

    jsPlumb.addEndpoint($('.leftTree tbody').children().filter('.left'), {}, endPointLeft);
    jsPlumb.addEndpoint($('.rightTree tbody').children().filter('.right'), {}, endPointRight);

    // delete connection when clicked on
    jsPlumb.bind('click', function (connection, e) {
        jsPlumb.detach(connection);
      });
  });

但每次我连接两个点时，都会出现以下错误＆＃34;错误：＆lt; svg＆gt;的值无效属性width =＆＃34; -Infinity＆＃34; ＆＃34;和＆＃34;错误：＆lt; svg＆gt;的值无效属性height =＆＃34; -Infinity＆＃34;＆＃34;。

有人知道如何修复它吗？
