Quick help with jQuery and JS.

Hi! Just writing out some Javascript for a site I am working on and I am using jQuery to help out.

However, I have encountered an error. I am trying to print the value of the variable I have created but it is returning 'undefined' in the alert box! I haven't done JS in a while so any pointers and help are greatly appreciated!

$("#registerButton").click(function() {
    var hotelName = $("#hotelName").val();
    alert(hotelName);
});

Thank you!

-Luke

There's not a lot of code to go on here but it looks like you're trying to get the value of an empty variable. I know you've assigned #hotelName to it but I'm assuming that's the id to a div with that name. You're trying to get a value to a variable but one that you can't do anything with.

My thought is that if you want whatever is contained in #hotelName you might want to use innerHTML rather than val?

But I may have got the wrong end of the stick with what you want. :-)

Hi Jonathan!

Thank you for the reply! Sorry, I have just realised how little code I have included! The #hotelName element is an input field for text in this case.

Thank you for all your help thus far!
