在cytoscape.js中禁用将节点拖到区域之外 [英] Disable dragging nodes outside of area in cytoscape.js

问题描述

我正在使用 cytoscape.js 。

我已允许用户拖动节点，但是正确现在也可以将节点拖到画布之外。

I have allowed the user to drag the nodes, but right now it is also possible to drag the node outside of the 'canvas'.

我在 http://js.cytoscape.org/#core/initialisation ，但我不知道如何确保节点不能离开可见区域< div id = cy>< / div> 。

I have looked at the options at http://js.cytoscape.org/#core/initialisation but I don't know how to make sure the nodes cannot leave the visible area <div id="cy"></div>.

推荐答案

尝试使用automove扩展名： https://github.com/cytoscape/cytoscape.js-automove

Try the automove extension: https://github.com/cytoscape/cytoscape.js-automove

它允许您设置节点位置的规则，例如在当前视口或指定区域内进行约束。

It lets you set rules for node position, like constraining within the current viewport or a specified region.
