有没有一种方法可以获取与DOM元素关联的cystoscape对象？ [英] Is there a way of getting the cystoscape object associated with a DOM element?

问题描述

我目前正在执行以下操作：

I currently do the following:

let $cy = $('#cy');
let cy = cytoscape({
   container: $cy,
   ...
});

$cy.data('cytoscape', cy);

以上内容使我可以重新获取cytoscape对象（例如在事件处理程序中），如下所示：

The above allow me to reobtain the cytoscape object (e.g. in a event handler) as follows:

let cy = $cy.data('cytoscape');

是否有内置的方法来获取cytoscape对象，因此我可以避免做所有这些工作（从技术上讲

Is there a builtin method of obtaining the cytoscape object so I can avoid doing all this work (and technically mess with a element own by the library)?

推荐答案

通常假定您将Cytoscape实例保留在一个共享变量中。代码，因此您无需从DOM对象获取它。

It is generally assumed that you will keep Cytoscape instance in a shared variable in the code, so you won't need to get it from the DOM object.

您可以像以下这样获取与DOM元素关联的Cytoscape实例：

You can get the Cytoscape instance associated with a DOM element like this:

 document.getElementById('cy')._cyreg.cy

请注意，据我所知，这没有记录。

Be aware, as far as I know this is not documented.
