GoJS
#1

I have question “how to change DIV on left form after drag and drop from palete to diagram without click button?”

I try take save function into nodeTemplateMap.add

<span =“Apple-tab-span” style=“white-space:pre”> myDiagram.nodeTemplateMap.add("", // the default category

<span =“Apple-tab-span” style=“white-space:pre”> $(go.Node, “Spot”, nodeStyle(),
new go.Binding(“location”, “loc”, go.Point.parse).makeTwoWay(go.Point.stringify),
$(go.Panel,
<span =“Apple-tab-span” style=“white-space:pre”> { contextMenu : nodeMenu}
<span =“Apple-tab-span” style=“white-space:pre”> ,
<span =“Apple-tab-span” style=“white-space:pre”> “Auto”,
<span =“Apple-tab-span” style=“white-space:pre”> $(go.Shape, “Rectangle”,
<span =“Apple-tab-span” style=“white-space:pre”> { minSize: new go.Size(40,60), fill: block, stroke: null}
<span =“Apple-tab-span” style=“white-space:pre”> ),
$(go.TextBlock,
{ font: “bold 11pt Helvetica, Arial, sans-serif”,
//stroke: lightText,
<span =“Apple-tab-span” style=“white-space:pre”> stroke: redgrad,
margin: 8,
maxSize: new go.Size(160, NaN),
wrap: go.TextBlock.WrapFit,
editable: true },
new go.Binding(“text”, “key”).makeTwoWay()),
{ click: function(e, obj) { save(); } }
),
// four named ports, one on each side:
makePort(“T”, go.Spot.Top, false, true),
makePort(“L”, go.Spot.Left, true, true),
makePort(“R”, go.Spot.Right, true, true),
makePort(“B”, go.Spot.Bottom, true, false)
)
<span =“Apple-tab-span” style=“white-space:pre”> );<span =“Apple-tab-span” style=“white-space:pre”>
…

<span =“Apple-tab-span” style=“white-space:pre”> function save() {
<span =“Apple-tab-span” style=“white-space:pre”> var str = myDiagram.model.toJson();
<span =“Apple-tab-span” style=“white-space:pre”> document.getElementById(“mySavedModel”).value = str;
<span =“Apple-tab-span” style=“white-space:pre”> }

Are you asking how to automatically save the diagram each time the user has changed something?

If so, implement a Model Changed listener that saves the model after a Transaction ChangedEvent. The Planogram and Record Mapper samples demonstrate this, although they just save the model to a text element on the page so that you can see it.
