Is there a quick way to get the value of a key starting with a certain string?
Example :
var obj = {
"key123" : 1,
"anotherkey" : 2
}
obj['key1'] // would return 1
obj['ano'] // would return 2
Thanks
You can create a helper function
function findValueByPrefix(object, prefix) {
for (var property in object) {
if (object.hasOwnProperty(property) &&
property.toString().startsWith(prefix)) {
return object[property];
}
}
}
findValueByPrefix(obj, "key1");
As Kenney commented, the above function will return first match.
