I need a function to filter array of objects based on given structure of object. So I have this object:
{
"2": [
{
"fd_id": 16,
...others
}
],
"3": [
{
"fd_id": 2,
...others
},
{
"fd_id": 3,
...others
}
]
}
I would like to filter another array based on this object. Like this;
const result = products.filter(item => {
// returns array of numbers [1, 2, 3]
const filters = item.filters;
if(filters){
// Here must be refactored
return ((filters.includes(givenObj[2][0].fd_id))
&& (filters.includes(givenObj[3][0].fd_id) || filters.includes(givenObj[3][1].fd_id)));
}
});
But this function must be dynamic. Because the input object may change. So for between each parent "&&", and between each children "||" condition must be applied. Thanks for any help. This is the link to example https://jsfiddle.net/cadkt86n/
A function to loop the data will help.
My Logic
fd_ids from the groups using Array.mapproducts array. Check for the matching combination in filters node of products array. Condition is there should be a matching combination in each nodes of fdIdList array.Working Fiddle
var groups = {
"2": [
{ "fd_id": 16, "fd_fRef": 2, "fd_ad": "35 - 50", "fd_siraNo": 255, "checked": true }
],
"3": [
{ "fd_id": 2, "fd_fRef": 3, "fd_ad": "KURU", "fd_siraNo": 255, "checked": true },
{ "fd_id": 3, "fd_fRef": 3, "fd_ad": "KARMA", "fd_siraNo": 255, "checked": true }
]
}
// Aggregates the list of fd_id s - This wil be an array of arrays
// [[16],[2,3]] => This will be the value
const fdIdList = Object.values(groups).map(a => a.map(b => b.fd_id));
var products = [
{
"id": 1,
"filters": [2, 3, 4, 13, 16, 17, 18, 19, 31, 48, 309, 318],
},
{
"id": 2,
"filters": [2, 3, 4, 13, 15, 17, 18, 19, 31, 48, 309, 318],
}
];
// Check if there is a common element in each node of fdIdList
var result = products.filter(item => {
const filters = item.filters;
if (filters) {
let isFound = true;
fdIdList.forEach(idListNode => {
isFound = isFound && idListNode.filter(value => filters.includes(value)).length > 0;
})
return isFound
}
});
console.log(result)
