Updating data using Angular 6's *ngFor directive based on the selected item from a dropdown menu

Within my application, there is a drop-down menu where users can select the specific data they wish to view and potentially edit. While I am able to update input data using the drop-down selection, I am encountering an issue with an *ngFor loop that dynamically populates the page with data from a hash table. My goal is to fetch data from the hash table based on the item selected in the drop-down menu.

Below is an example of the code:

https://stackblitz.com/edit/angular-dmyqrn

Currently, I have set it up to load sample input data defined as a constant

SOURCE_DESTINATION_PARAMETERS_VALUES_DATA

This constant references the DATA00 hash, but I do not want it to be static. I am unsure how to dynamically assign this data to update the other fields automatically.

Does anyone have any suggestions on how this can be achieved?

Answer №1

Apologies!

I have realized that by using a switch statement, I am able to assign values within the onChange function in order to reset the value of 

this.sourceDestinationParametersValuesData
. Additionally, I had forgotten to include this. in my initial attempt to modify the data object.

Despite these setbacks, I found the solution available at:
