menu:[{
id:''
name:'',
child:'[{
id:''
name:'',
child:'[]'
}]'
}]
This child element is nested infinitely.How to loop over this tree to get data of the passed id of the child?
let obj = {
menu:[{
id:1,
name:'Raj',
child:[{
id:2,
name:'vivek',
child:[{
id:3,
name:'sameer',
child:[{
id:4,
name:'sahil',
child:[]
}]
}]
}]
}]
}
let userInput = 2;
function checkid(obj1){
let {
id,
name:cname,
child
} = obj1;
if(id === userInput){
return obj1;
}
else{
return checkid(child[0]);
}
}
console.log(checkid(obj.menu[0]));
I hope this helps you!!
function handleElement(el){
if('id' in el){
// do something with el['id']
}
if('child' in el){
handleElement(el.child)
}
}
for (const el of menu){
handleElement(el)
}
