javascript - cytoscape js 通过选择器遍历节点

Question

如何根据选择器遍历 cytoscape js 网络中的节点？

我知道我可以使用

cy.filter(".myselector")

它返回一个复杂的对象，例如:

0: ua {0: ua, length: 1, _private: Object, instanceString: function, spawn: function, spawnSelf: function, …}

1: ua {0: ua, length: 1, _private: Object, instanceString: function, spawn: function, spawnSelf: function, …}

2: ua {0: ua, length: 1, _private: Object, instanceString: function, spawn: function, spawnSelf: function, …}

_private: {cy: Wa, map: Map}

length: 3

这是我开发的基于选择器遍历图形的方法(并获取感兴趣的元素，在我的例子中是节点的名称)

注意名称是如何检索的，即_private.data.name

var entire_object, no_of_objects, objects_array = []; 
entire_object = cy.filter(".myselector"); //returns a complex object with nodes matching ".myselector" filter
no_of_objects = entire_object.length; //the number of cytoscape nodes 

for (var i = 0; i < no_of_objects; i++){
  object_name = {};
  object_name = entire_object[i]._private.data.name; 
  objects_array.push(object_name);
}
