I have the following data as a nested array please see the below fiddle https://jsfiddle.net/athulmathew/z3s1w0mu/ I want to get the output from the array-like below
var item {caller_number_raw : data from the array,company_id:data from the array}
I tried to sort it like this
for (i in data.data.hits) {
for (j in data.data.hits[i]._source) {
//str += data.data.hits[i]._source[j] + "<br/>";
var Item ={CallerID:data.data.hits[i]._source[j].caller_number}
console.log(Item)
}
}
but returns an empty object "{}" I am not that familiar with nested arrays can anybody help me what I am doing wrong here
_source is just an Object, you don't have to iterate over its property in order to get a specific property, you can replace the second loop with just var Item ={CallerID:data.data.hits[i]._source.caller_number} .
Also, since data.data.hits is an array, it is more appropriate to use for...of or a normal for loop instead of for...in.
Here is an example:
for (const hit of data.data.hits) {
const item = { CallerID: hit._source.caller_number };
console.log(item);
}
Event though the example above will work, it will not produce the required output the you've mentioned, to do that, you can use something like this:
for (const hit of data.data.hits) {
const item = { caller_number_raw : hit.caller_number_raw, company_id: hit.company_id }
console.log(item);
}
If you want to store all the newly created objects into an array, you can do something like this:
const output = [];
for (const hit of data.data.hits) {
output.push({ caller_number_raw : hit.caller_number_raw, company_id: hit.company_id });
}
console.log(output);
This is even easier using a functional approach:
const output = data.data.hits.map(({ caller_number_raw, company_id }) => ({ caller_number_raw, company_id }));
here you don't need the second for in loop because _source is an object.
for (let i in data.data.hits) {
if(data.data.hits[i]._source.caller_number){
var Item = {
CallerID: data.data.hits[i]._source.caller_number
}
console.log(Item)
}
}
Here is the jsFiddle link of the solution.
