Problem with adding keypress to wikipedia api (problem solved)

So I created a Wikipedia API where I wanted to add a keypress function. Instead of just clicking the Submit button to make the Ajax call, the user can do it by hitting the enter key. I have the code, but it’s not working. Any help in appreciated.

Here is the HTML Code:

                      <form id="wiki_category">
				<input type="text" placeholder="Find an article's categories" id="category-term">
				<button id="category-button" type="button">Submit</button>
			</form>

Here is the script code:

function getCategories(){
	//gets search input
	var category = $('#category-term').val();
	//api url with search term
	var link = "https://en.wikipedia.org/w/api.php?action=parse&page=" + category + "&prop=categories&format=json&callback=?"
	
	$.ajax({
		type:"GET",
		url:link,
		async:false,
		dataType: "json",
		success: function(data){
			//necessary to erase the old content
		//$('#output').html('');
	
			for(var i=0;i<data.parse.categories.length;i++){

				var category_Word = data.parse.categories[i]["*"];
				var category_Link = "https://en.wikipedia.org/wiki/Category:" + category_Word

				console.log(category_Word);
				console.log(category_Link);

				$('#output').append("<li><a href= " + category_Link + ">" + category_Word + "</a></li>");
				//add an error message
			}
		}
	})
}


$(document).ready(function(){
	//when search button is clicked, run code
	$('#category-button').on('click', function(){
		getCategories();
	});

	$('#category-term').keyup(function(e){
		if(e.keyCode == 13){
			getCategories();
		}
	})

});

Any help would be good. Thanks

I was able to work it out. If you want to add a keypress function to your api, here is some code I stumbled upon:

$(document).ready(function(){
	//when search button is clicked, run code
	$('#category-button').on('click', function(){
		getCategories();
	});

	$('#category-term').keypress(function(e){
		console.log(e)
		if(e.keyCode === 13){
			$('#output').append("<li><a href= " + category_Link + ">" + category_Word + "</a></li>");
		}
	})

});
