JQuery :: When Click On A Button Call As "resetBtn" It Will Alert Out "asd"

$("#resetBtn").click(function() {
alert ("asd");
});

This is my current code for the jquery (above) and html (below).

<form id="myform" method="post">
<input type="button" name="reset" value="Reset" id="resetBtn" /></form>

I am new to jquery and I want to create my own basic function using jquery.The function i want is when i click on a button call as "resetBtn", it will alert out "asd". But my code doesn't work for me.

if i was to change my current code to class instead of id, does it affect other button with same class name in the same form? what if the buttons are in different forms? (same question as 2nd question)
