collection
[{
"title":"Completed",
"details":[[dateA,timeA],[dateB,timeB]]
},{
"title":"Unfinished",
"details":[[dateC,timeC],[dateD,timeD]]
}]
If I need to transfer the title "Unfinished" and details [dateC,timeC] to a separate array, what is the method to accomplish this?
Start by identifying the object within the array using its key. Let's say your array is stored in a variable named mylist
var issue = mylist.find(function(item){ return item.key === 'Failed'; });
Now, if you have a new array:
var failedList = []; // your new array
failedList.push({
key: issue.key,
values: issue.values[0] // assuming you only need the first value
});
There might be a more efficient way to accomplish this. It would be helpful if you can provide additional details on your desired outcome.
UPDATE:
If your intention is to extract all failed results from the array and organize them into a subgroup, you can utilize the reduce method as shown below.
var failedList = mylist.reduce(function(accumulator, item) {
if(item.key === 'Failed'){
var data = {
key: issue.key,
values: issue.values[0]
};
accumulator.push(data)
}
return accumulator;
}, []);
Applying pure JavaScript
let failedItems = [];
for(let i=0; i<array.length; i++){
if (array[i]['status'] === "Failed"){
failedItems.push(array[i]);
}
}
failedItems now holds all the failed entries.
What is the objective? We have two arrays: orders and NewOrders We need to check for any orders with the same order_id in both arrays. If there is a match, we then compare the order status. If the order from the NewOrders array has a different status, w ...
