如何从mysql表中获取cytoscape.js中的节点和边数据

Question

I have a display network using cytoscape.js, I want to display details from mysql table about a particular node and edge whenever the node is clicked. How can I do that?

I have used the following code which uses function cy.on ('tap'). How do I send the var node_id to any php page which then use this node and retrieve its information from a mysql table to display the information in a particular division. This code is inside a $.getJSON function.

        cy.on('tap', 'edge',  function(evt){
          var edge = evt.cyTarget;
          alert( 'Selected ' + edge.source() );
        });
        cy.on('tap', 'node',  function(evt){
          var node = evt.cyTarget;
          alert( 'Selected ' + node.id() );
        });

If i understand your question correctly, you can just send an HTTP request containing node_id to your server.

If you don't know how to do this in javascript, I suggest taking a look at the MDN page for XMLHttpRequest
