I need to retrieve an array of keys from an object that match a specified value
I need to retrieve an array of keys from an object that match a specified value
One approach to achieve this is by utilizing the Object.keys() method:
const selectedKeys = Object.keys(targetObj).filter(key => targetObj[key] == "02");
With this code, selectedKeys will store an array of keys from targetObj that have a value of "02".
To extract the keys of an object, you can utilize Object.keys() method and then proceed to filter out keys with values that match a specified value.
const sampleObj = {apple: 'red', banana: 'yellow', grape: 'purple', lemon: 'yellow'};
function findKeys(obj, value) {
return Object.keys(obj).filter(key => obj[key] === value);
}
console.log(findKeys(sampleObj, 'yellow')); //["banana", "lemon"]
console.log(findKeys(sampleObj, 'red')); //["apple"]I am having trouble displaying data in my Jqgrid.
