You don’t need jQuery to update your DOM elements.
I use a progress bar in my file transfer upload example. See the html and typescript to see how I update the progress. If you want a more detailed example I’d like to see some code (your html and typescript) to get me started.
If you really insist on using jQuery; without knowing the error you have gotten it is highly likely that you forgot to import jQuery in your typescript file.
First install the package.
npm install jquery --save
Install (typings and) the typings file
npm install -g typings
typings install dt~jquery --global --save
and finally, import the jquery to your ts file
import * as $ from 'jquery'
