Hi I have an array of objects which string starts with a specific prefix and if that key value is true then remove all the objects in an array that contains the same key(prefix)
below is the array of object:
const data = [{
field_name_key: "Recive_IsViaEmail",
fieldValue: false
},
{
field_name_key: "Recive_IsViaSMS",
fieldValue: false
},
{
field_name_key: "Sender_IsViaEmail",
fieldValue: false
},
{
field_name_key: "Sender_IsViaSMS",
fieldValue: true
},
]here "Sender_IsViaSMS" contains true hence remove all the objects that start with the prefix key Sender_IsVia
Final result is this:
const data = [{
field_name_key: "Recive_IsViaEmail",
fieldValue: false
},
{
field_name_key: "Recive_IsViaSMS",
fieldValue: false
}
]An inefficient but short solution would be to use Array.filter and set the condition of the callback to whether data contains an item with the same field_name_key property prefix and whose fieldValue property is true:
const data=[{field_name_key:"Recive_IsViaEmail",fieldValue:false},{field_name_key:"Recive_IsViaSMS",fieldValue:false},{field_name_key:"Sender_IsViaEmail",fieldValue:false},{field_name_key:"Sender_IsViaSMS",fieldValue:true}];
const res = data.filter(e => !data.find(f => f.field_name_key.split("IsVia")[0] == e.field_name_key.split("IsVia")[0] && f.fieldValue))
console.log(res)You can create a function that first finds the entries to remove, then remove one by one:
const data = [{
field_name_key: "Recive_IsViaEmail",
fieldValue: false
},
{
field_name_key: "Recive_IsViaSMS",
fieldValue: false
},
{
field_name_key: "Sender_IsViaEmail",
fieldValue: false
},
{
field_name_key: "Sender_IsViaSMS",
fieldValue: true
},
]
const sanitizeData = (list) => {
// find entry keys to remove
const toRemove = list.reduce((prev, el) => {
if(el.fieldValue === true) return el.field_name_key.split('_')[0]
})
// remove
const removed = list.filter(el => {
return !toRemove.includes(el.field_name_key.split('_')[0])
})
return removed
}
console.log(sanitizeData(data))Build up a list of the prefixes to remove first, then just run a filter.
I am not sure on how you are coming up with the prefix of a given field name however. Given your example you're expecting "Sender_IsViaSMS" to also purge "Recive_IsViaSMS". But you should be able to take this and adapt it as you see fit.
const data=[{field_name_key:"Recive_IsViaEmail",fieldValue:false},{field_name_key:"Recive_IsViaSMS",fieldValue:false},{field_name_key:"Sender_IsViaEmail",fieldValue:false},{field_name_key:"Sender_IsViaSMS",fieldValue:true}];
const prefixsToAxe = new Set();
// Having trouble with this part in your question, so ran with this, replace as you see fit
const determinePrefix = (field_name_key) => field_name_key.split('IsVia')[0];
for (const entryToAxe of data.filter(x => x.fieldValue === true)) {
const prefixToAxe = determinePrefix(entryToAxe.field_name_key);
prefixsToAxe.add(prefixToAxe);
}
const purged = data.filter(entry => {
const prefixInQuestion = determinePrefix(entry.field_name_key);
return !prefixsToAxe.has(prefixInQuestion);
})
console.log(purged)
