I tried to loop threw an array in order to count the occurance of 'phone1'. The Data from the backend has the following structure:
[{
Key: 'phone1',
Recording: {
ID: 'phone1',
Tel: '1000',
User: 'Maria',
Price: '350',
docType: 'asset'
}]
My function for this looks like:
backendData.list[0].map((phone, i) => {
var counter = 0;
for (var i = 0; i < backendData.length; i++) {
if (backendData[i].Key === 'phone1') counter++;
}
console.log(counter);
});
The result I get is always 0, but it has to be 1 with my Data.
Try this:
let counter = 0;
backendData.list[0].forEach((phone, i) => {
if(phone.Key === 'phone1') counter++;
console.log(counter);
})
You just can use Array.prototype.filter() to count objects by condition:
const backendData = [{Key:'phone1',Recording:{ID:'phone1',Tel:'1000',User:'Maria',Price:'350',docType:'asset'}}];
const result = backendData
.filter(({ Key }) => Key === 'phone1')
.length;
console.log(result);.as-console-wrapper{min-height: 100%!important; top: 0}
