How to grab content from another page?

I’m trying to using the .get() method but is my first time hehe.

const quickSilverBtn = $('#QS-btn');
    quickSilverBtn.on('click', function() {
    const lookbookWrapper = $('.lookbook-content-wrapper');
       $.get( "", function( data ) {
          $( "#man-qsilver-content" ).html( data );
          console.log( $("#man-qsilver-content") );

I want to grab the content from another page and put it on a div. What I need to do?
I’m very frustrated hehe
Thanks a lot people!
