Assigning value of one text box to another

You're not waiting for the DOM to become ready. You should write something like:
$(document).ready(function() {
$("#button").click(function() {
var contents = $("#textbox").val();
$("#container").val(contents);
});
});
Solution 2
Your code looks good. Just add it to the $(document).ready(...)
event handler like this:
$(document).ready(function() {
$("#button").click(function() {
var contents = $("#textbox").val();
$("#container").val(contents);
});
});
You could also simplify your code a bit:
$(document).ready(function() {
$("#button").click(function() {
$("#container").val($("#textbox").val());
});
});
Take a look at the .ready() docs.
Solution 3
You should wait for all elements with document.ready
event, and you can simplify your jquery:
$(document).ready(function() {
$("#button").click(function() {
$("#container").val($("#textbox").val());
});
});

Have looked at the answers to similar questions to this, but for the life of me, I can't figure out what I'm doing wrong.
I have a two text boxes and a button. When text is added to the first textbox and the button pressed, I want to apply the first textbox's value/text to the second textbox:
<html> <head> <script type="text/javascript" src="jquery.js"></script> <script> $("#button").click(function() { var contents = $("#textbox").val(); $("#container").val(contents); }); </script> </head> <body> <input type="text" id="textbox" /> <input type="submit" id="button" value="Press This" /> <br /> <input type="text" id="container" /> </body> </html>
