I have an array of objects
const target = [{name: 'srk@gmail.com', selected: false, alertType: 'max'},
{name: 'abc@gmail.com', selected: true, alertType: 'clear'},]
now i want to update the array based on name and alertType. for ex: if name and alertType matches then update the selected property. if that doesn't match add a new Object. new Object is
const = {name: 'srk@gmail.com', selected: false, alertType: 'both'}
You can use Array.find() to find any matching items. You'd then update if an existing item has been found, or add a new one if not:
const target = [
{name: 'srk@gmail.com', selected: false, alertType: 'max'},
{name: 'abc@gmail.com', selected: true, alertType: 'clear'}
];
const update = { name: 'srk@gmail.com', selected: false, alertType: 'both' };
function updateAlerts(input, update) {
let foundAlert = input.find(alert => ((alert.alertType === update.alertType) && (alert.name === update.name)));
if (foundAlert) {
foundAlert.selected = update.selected;
} else {
input.push(update);
}
}
updateAlerts(target, { name: 'srk@gmail.com', selected: false, alertType: 'both' })
console.log(target);
updateAlerts(target, { name: 'srk@gmail.com', selected: true, alertType: 'max' })
console.log(target);.as-console-wrapper { max-height: 100% !important; top: 0; }
