How get parent value

[rocky-bgta]

From this treeview we only get child tree value, How I get the parent node value?

[curvecode]

@rocky-bgta I can do it from here https://leovo2708.github.io/ngx-treeview/#/advanced

I want when all the children of a Parent are selected, then instead of the id of ​​the parent's children, the output is id parent? Can anyone help?

EXAMPLE

{
        text: 'Frontend',
        value: 911,
        children: [
             { text: 'Angular 1', value: 9111, checked:true },
             { text: 'Angular 2', value: 9112, checked:true },
             { text: 'ReactJS', value: 9113, checked:true },
         ],
 },

OUTPUT => 911

Answer

onSelectedChange(downlineItems: DownlineTreeviewItem[]): void {
    this.rows = [];
    downlineItems.forEach(downlineItem => {
      const rec = downlineItem;
      let parent = downlineItem.parent;
      let valueSelected: any = null;
      if (parent.item != null && !parent.item.children.some(ele => ele.checked !== true)) {
        valueSelected = parent.item.value;
        parent = parent.parent;

        while (!isNil(parent)) {
          if (parent.item != null && !parent.item.children.some(ele => ele.checked !== true)) {
            valueSelected = parent.item.value;
          }
          parent = parent.parent;
        }
      } else {
        valueSelected = downlineItem.item.value;
      }


      if (!this.rows.some(ele => isEqual(ele, valueSelected)))
        this.rows.push(valueSelected);
    });
  }

For the past 2 years, people are complaining about this issue. Don't think it's going to be resolved soon. It's time to look for another package that supports this functionality.
