javascript：Deep loop Json objects，and then output special formate simple objects, how?
-4
My JSON object data：
{
"title": "aa",
"desc": ["i", "j", "k"],
"cnt": {
"head": "bb",
"main": {
"num1": {
"time1": "mm",
"time2": "kk"
},
"num2": "dd"
}
}
}
My question is: How do I translate the above JSON object to the below by using JavaScript?
{
"title": "aa",
"desc": ["i", "j", "k"],
"cnt_head": "bb",
"cnt_main_num1_time1": "mm",
"cnt_main_num1_time2": "kk",
"cnt_main_num2": "dd"

You're basically asking how to flatten a nested object, with the keys representing the nested path. Here's a little recursive function that does just that:
const flatten = (o, pre) => Object.entries(o).reduce((a, [k, v]) => (
key = pre ? `${pre}_${k}`: k,
{
...a,
...Object.getPrototypeOf(v) !== Object.prototype ? {[key]: v} : flatten(v, key)
}), {});
Full snippet:
const o = {
"title": "aa",
"desc": ["i", "j", "k"],
"cnt": {
"head": "bb",
"main": {
"num1": {
"time1": "mm",
"time2": "kk"
},
"num2": "dd"
}
}
};
const flatten = (o, pre) => Object.entries(o).reduce((a, [k, v]) => (
key = pre ? `${pre}_${k}`: k,
{
...a,
...Object.getPrototypeOf(v) !== Object.prototype ? {[key]: v} : flatten(v, key)
}), {});
console.log(flatten(o));answered Dec 28 '18 at 3:40
