API Help

Hey there, I am doing a project on freeCodeCamp and I am having trouble with my API. It does not always return a value for me. I am testing it in the console and sometimes it returns, and sometimes it won't. It is not consistent at all.

Here is my project: https://codepen.io/tsjohns9/pen/yXRwwE?editors=1011

And here is the challenge from FCC: https://www.freecodecamp.com/challenges/build-a-wikipedia-viewer

Hey Trevor, looks like you just about solved it, nice work following the docs! What's happening now is that when the form is submitted, the default behavior is to send that data to a server, and refresh the page...but that's typically not how web apps are made this days. What you want to do is prevent that default behavior and just have the requested information display, without a page refresh.

To accomplish this, the line

$('#lookUp').submit(function() {

also takes in an event object as a parameter:

$('#lookUp').submit(function(event) {

and just below that, you want to include the line event.preventDefault() That will stop the page from refreshing (thus removing the info from wikipedia) and everything should display nicely in the console.

Hey Trevor, your JS is setup with an event listener on your button...and only your button. The problem is that since you're in a form element, the user can both hit enter after typing text--doesn't work, or click the button--works.

A (wrong) solution, would be to add another event handler that does the exact same thing, but assign it to the input field. The nice thing about form elements however, is that they come with a handy onSubmit method that will do both: listen to when the enter key is pressed on the input, or any nested buttons are clicked. I'll let you find the way to implement this ;) but chances are you've heard of this method before. Good luck!

Hey Michael, I am still struggling here. Check out what it is updated to now. It should be right based off of the documentation for the submit method. It is still randomly displaying the requested JSON regardless of if I hit enter or click. If I made a mistake in understanding how to use the submit method let me know and i'll take care of that.
