我的javascript组件未呈现，并且出现以下错误：
TypeError: $(...).cytoscape is not a function
这是引发错误的代码。
本质上，我正在尝试隔离JavaScript渲染到行内容的内容。当我运行此程序而不将其嵌套在容器中时，它可以正常工作。

$('#cy').cytoscape({
layout: {
name: 'cose',
padding: 10,
randomize: true
},
...
};
需要更改为
var cy = cytoscape({
container: $('#cy'),
layout: {
name: 'cose',
padding: 10,
randomize: true
},
...
};
按照http://js.cytoscape.org/#getting-started/initialisation上的说明
这将解决您的错误，但是我不确定它是否正在渲染您希望的样子。我希望这至少可以使您距离期望的行为更近一步！
