Why is the hide not working?

I have a JQuery/JavaScript code that I am using in a script. For some reason which I can't seem to find, the Hide() function is not working. What could be the issue? What did I do wrong?

JavaScript

$("#vertebrateAnimalsYes").hide();

$("#vertebrateAnimals").setOnchange(function(newVal, oldVal) {
    if (newVal == "no")
        $("#vertebrateAnimalsYes").disableValidation();
  		$("#vertebrateAnimalsYes").hide();
    if (newVal == "yes")
        $("#vertebrateAnimalsYes").enableValidation();
  		$("#vertebrateAnimalsYes").show();
});

What I have tried:

JavaScript

$("#vertebrateAnimalsYes").hide();

$("#vertebrateAnimals").setOnchange(function(newVal, oldVal) {
    if (newVal == "no")
        $("#vertebrateAnimalsYes").disableValidation();
  		$("#vertebrateAnimalsYes").hide();
    if (newVal == "yes")
        $("#vertebrateAnimalsYes").enableValidation();
  		$("#vertebrateAnimalsYes").show();
});

Check your browser's developer tools for errors. Make sure your document contains precisely one element with the specified ID. Make sure your code isn't running before the DOMContentLoaded event.

Beyond that, nobody can help you. Debugging your code requires access to your page, so only you can debug it.

JavaScript isn't Python, indentation does not create code blocks.

As you wrote it originally, disableValidation and enableValidation are executed conditionally, whereas Hide() and Show() are always executed (in that order), so nothing gets hidden.

Your "solution 1" switched things around, I doubt it is what you really want. Your code needs brackets so it executes either the first two or the last two method calls, and not three out of four of them.

JavaScript

$("#vertebrateAnimals").setOnchange(function(newVal, oldVal) {
    if (newVal == "no")
        $("#vertebrateAnimalsYes").hide();
  		$("#vertebrateAnimalsYes").disableValidation();
    if (newVal == "yes")
        $("#vertebrateAnimalsYes").show();
  		$("#vertebrateAnimalsYes").enableValidation();

Why is the hide not working?
