Hello i use Thanks in advance for your help.
I'm trying to save this data to the database but I can't. I searched on the internet but couldn't find enough results. I will be very happy if you help me
CodePudding user response:
You can iterate the tree recursively keeping track of current parent, then pushing to db each of its children as child - parent.
var tree = [{id:"1",children:[{id:"2",children:[{id:"3"},{id:"4"},{id:"5"},{id:"6"},{id:"7"},{id:"8"},{id:"9"},{id:"10"}]},{id:"11",children:[{id:"12"},{id:"14"},{id:"13"},{id:"15"},{id:"16"}]}]}];
var db = [];
function iterate(children, parent) {
parent = parent || 0;
children.forEach(function(child) {
db.push ({child: child.id, parent: parent})
if (child.children) {
iterate(child.children, child.id)
}
})
}
iterate(tree)
console.log(db)
