Imagine I have a map data type
exampleMap: Map<string, any>
The key in the map is always a string, and the corresponding value is an object.
This object might look like this:
{ name: 'sampleName', age: 30}
Now, let's say the user selects an element using a dropdown menu.
How can I change the name property of the object to match its key in the map?
I've already tried iterating over the map with forEach and using Map.get() and Map.set(), but it didn't work as expected.
Is this something you were looking for?
// If you already have the testMap defined
// testMap: Map<string, any>
// Step 1: Obtain the selected key from the dropdown (ensure to replace 'selectedKey' with the actual key that was selected)
const selectedKey = 'someKey';
// Step 2: Fetch the corresponding object from the map
const selectedObject = testMap.get(selectedKey);
// Step 3: Modify the "name" property of the object
if (selectedObject) {
selectedObject.name = selectedKey;
} else {
// Address the scenario where the selected key is not in the map
console.error('Selected key not found in the map!');
}
// Step 4: Update the object back into the map using the same key
testMap.set(selectedKey, selectedObject);
// At this point, the "name" property of the chosen object in the map will reflect the selected key.
