Guide to modifying dropdown selection based on user input

Currently immersed in a Rails project where I am integrating a text_field and a select_tag. My goal is to establish a connection between the two fields and have the select_tag value change dynamically based on the input in the text_field.

For instance: In my drop-down list, there are two options: numbers and alphabets. If '12345' is inputted, the drop-down menu will automatically switch to 'numbers'. If 'hello' is entered, the drop-down box will automatically switch to 'alphabets'.

Being a novice in web programming, it would be incredibly helpful to receive guidance on how to implement this jQuery script in Rails as well!

Many thanks in advance!
