This is the main body of the code. Basically I am trying to write the client side page for a chat server. Assuming the server interaction is correct the page will never be able to take the messages sent back from the server because the page refreshes every time I hit the enter. The code is supposed to send a message to the server and then the server sends the message to all connected clients and the client appends the message to the end of the list.

The main culprit for this reload is the enter chat function:
$("#enterChat").click( function() {
var messageValue = $("#chatMessage").val();
console.log("Entered by User: %s", messageValue);
sendChat(messageValue);
});
If anyone could point me towards why the page is reloading I could actually work towards seeing if the message from the server is being passed properly. On top of that I would really appreciate it.
You can just add this
To prevent the default behavior of form submission on enter.
