Select node list item dynamicaly

Hi ,

I want to do automation testing on Nodes , by simulating node click and node selection etc.

How can i select node by passing its index.
say …go.Diagram.fromDiv(graphDiagram).select(0) etc

i can get the selection node location by…

The value of graphDiagram appears to be an HTML DIV element. Is that correct?

If so, then evaluating go.Diagram.fromDiv(graphDiagram) will get you a Diagram object, from which you can do anything.

You might want to do:

    var node = diagram.findNodeForKey(...);
    if (node !== null) {
        var viewpos = diagram.transformDocToView(node.location);
        // viewpos is in coordinate system of graphDiagram DIV


Yes it is HTML DIV element ,

can you pass me example to select any node

ex : go.Diagram.fromDiv(graphDiagram).select(0) where 0 is inxex or node Id or node name etc

I just gave you that code. You just need to know the unique key of the desired node in the model. That will be a string or a number.

i am able to get the nodeData List through go.Diagram.fromDiv(graphDiagram).model.nodeDataArray[0] ,

how to view the node content ( i have button inside the node ) want to click on it through automation.

If you have given the button a (i.e. { name: "BUTTON" }), then you can do something like:

    var button = node.findObject("BUTTON");
    if (button !== null) {
        var buttonpos = diagram.transformDocToView(button.getDocumentPoint(go.Spot.Center);
        // buttonpos is in coordinate system of the DIV

not able to find button inside the selected node , ( i have added button inside node) . Any other way to find ?

Sample node template :

 var nodeTemplate =
	goJ(go.Node, "Vertical",
		new go.Binding("location", "loc"),
		{ isShadowed: true,shadowColor:"#cccccc",shadowBlur:5},
		{ selectionObjectName: "BODY" },
		goJ(go.Panel, "Auto",
			{ name: "BODY"},
			goJ(go.Shape, "RoundedRectangle",
				{ fill: "transparent" , stroke: "#67D5E0", width:200, height:54},				
				goJ(go.TextBlock,{ font:'12px roboto', textAlign: "center", wrap: go.TextBlock.WrapFit, width:180,margin: new go.Margin(2, 1, 22, 1)}, new go.Binding("text", "value",scope.getNodeText)),
				goJ("Button",new go.Binding("location", "loc"),{margin:1,alignment: new go.Spot(0, 1),cursor: "pointer"},
					goJ(go.Picture,{source: "images/add-plus-blue.png"}),{
						click: scope.tets

It’s hard for me to read your unindented code. Code Formatting

It does not appear as if you gave the “Button” a name as I suggested in my previous reply.

please find the formatted sample code , do you see i need to add anything in button ?

If you want to run the code I gave you in my reply, you need to give your button a name, as I gave in that same reply.

Thanks Walter , i am able to get the selected node button location details …

similarly , How to get link location information ?

The same techniques work for GraphObjects within links as well as in nodes.
