How to get data with state from tree?

[ghost]

Hello,
is there a possibility to save the changed state in a json from the tree?
For example I have a predefined tree with no checked node. How can I get the data json with the checked nodes?
Best Regards

Thanks, the function toJSON gives me the data I want.
Is there a function to filter the state? In my project I only need the state "checked" and "indeterminate".

You can use either https://amsik.github.io/liquor-tree/#Tree-find-criteria-multiple-false or filter method of vanilla js

I wrote a function for JSON.stringify to extract the needed states.

var replace = function(key, value) {
  switch (key) {
    case "selected":
    case "selectable":
    case "expanded":
    case "disabled":
    case "visible":
    case "matched":
    case "editable":
    case "data":
      return undefined;
      break;
     case "children":
       if (value.length > 0) {
         return value;
       } else {
         return undefined;
       }
       break;
     default:
       return value;
  }
};
var treeModel = JSON.stringify(this.$refs.tree.toJSON(), replace);

This works fine to get a JSON String with the needed information.

Other question:
Which data can be stored in the data object in the data property of a tree node? Is it possible to put other information which are not relevant to the tree node expected data?

The property data is a single object on node. You can put any data to this object :)
