Create a new JSON after manipulating json values in angular6 - json

Question

Below is my JSON
[
{
"Key": "doc/1996-78/ERROR-doc-20200103.xlsx"
}
},
{
"Key": "doc/1996-78/SUCCESS-doc-20200103.xlsx"
},
{
"Key": "doc/1996-78/PENDING-doc-20200103.xlsx"
}
]
First i want to split key value by backslash and after that will split the [2] json value by hyphen and then will check in string that if there is SUCCESS/PENDING/ERROR word found in the newly spitted JSON. If any word is present would like to add new status field and add Done/Processing/Failure respective values in newly created JSON. this is a dynamic json so without manipulating it i can't get status value
This is what i would like to achive in my new JSON
[
{
"Key": "doc/1996-78/ERROR-doc-20200103.xlsx",
"status":"Failure"
}
},
{
"Key": "doc/1996-78/SUCCESS-doc-20200103.xlsx",
"Status":"Done"
},
{
"Key": "doc/1996-78/PENDING-doc-20200103.xlsx",
"Status":"Processing"
}
]
As i'm new to this kindly let me know how to achieve this

Answer 1

You can use includes function and if true then add string.
Try my code:
let myJson = [
{
"Key": "doc/1996-78/ERROR-doc-20200103.xlsx"
},
{
"Key": "doc/1996-78/SUCCESS-doc-20200103.xlsx"
},
{
"Key": "doc/1996-78/PENDING-doc-20200103.xlsx"
},
{
"Key": "doc/1996-78/WRONG-doc-20200103.xlsx"
}
];
myJson = myJson.map(obj => ({
...obj,
"Status": obj.Key.includes("ERROR") ? 'Failure' : obj.Key.includes('SUCCESS') ? 'Done' : obj.Key.includes('PENDING') ? 'Processing' : false
}))
console.log(myJson)

Answer 2

for(let object of objectArra) {
if(object.key === 'doc....')
object['status']="Failure";
else if (object.key === 'doc..')
object['status'] = "Done";
else if....
}
Iterate on object array if the key is equal to that you want status is "failure", you insert a status property in the object with "Failure" as value ...

Answer 3

This can be achieved in the following way
yourArrayName.forEach((val)=>{
if(val.Key.includes('ERROR')){
val['Status']="Failure"
}
else if(val.Key.includes('SUCCESS')){
val['Status']="Done"
}
else if(val.Key.includes('PENDING')){
val['Status']="Processing"
}
})
Hope it helps!

How to do it in ES 6
The key advantage is the use of Regex which makes it more flexible to other requirements than includes.
const data = [
{
"Key": "doc/1996-78/ERROR-doc-20200103.xlsx"
},
{
"Key": "doc/1996-78/SUCCESS-doc-20200103.xlsx"
},
{
"Key": "doc/1996-78/PENDING-doc-20200103.xlsx"
}
];
data.map((entry) => {
let status;
if (/^.*ERROR.*$/.test(entry.Key)) {
status = 'Failure';
} else if (/^.*SUCCESS.*$/.test(entry.Key)) {
status = 'Done'
} else if (/^.*PENDING.*$/.test(entry.Key)) {
status = 'Processing'
}
return {...entry, status};
});
