[FIXED] How to use the :not selector in Cytoscape.js? (To select nodes that don't have an attribute)

Issue

I'm trying to use the :not selector in cytoscape.js. I want to select all nodes that don't have a specific attribute to open an context menu. E.g.:

cy.cxtmenu({
    selector: not('node.selection'),
    commands: [ .... ]
});

But I'm not sure how I can do this in cytoscape.js. Any help will be welcome.

Solution

[^name] Matches elements if the specified data attribute is not defined, i.e. undefined (e.g [^foo]). Here, null is considered a defined value.
