First off, I'm not experienced with JavaScript. Although I plan on sitting down and thoroughly learning the language, for now I'm just an HTML/CSS guy. I say this to avoid having my mind-blown by a response.
I'm having an issue with a site I've inherited. They've used what I believe is a script written by someone else for an image slider, and the page keeps coming back with the error I mentioned in the title. I'll post the code and hopefully someone can help me fix it (and teach me some things about JavaScript in the process).
CODE: The error Google Developer tools is sending back occurs on the very last line (JQuery)

It is on the last line that I receive Uncaught TypeError: object is not a function
Any ideas?
$(document).ready(function($) {
Not returning function so you should remove
})(jQuery)
And replace to
});
Also there is no need to pass $ to ready handler and you can simplify it from:
$(document).ready(function($) {
To
$( function() {

Many thanks in advance for any help and advice.

The source you posted doesn't seem to be the latest version of Roundabout.
I just tried with the latest version, and it works perfectly:
$(document).ready(function() {
$('ul').roundabout({
autoplay: true,
autoplayDuration: 1000,
autoplayPauseOnHover: true
});
});
See http://jsfiddle.net/SfAuF/ for an example.
Download the latest version from GitHub.
I needed to make a floating menu, I searched online and found a script here http://www.jtricks.com/javascript/navigation/floating.html

};
}) (jQuery);
}
The script requires the menu to have #floatdiv id. I made my div, #floatdiv, and added the following line of javascript to the head to make the action start working:
<script type="text/javascript">
floatingMenu.add('floatdiv',
{
targetLeft: 250,
targetTop: 290,
snap: true
});
</script>
the #floatdiv css is here,
#floatdiv{
height:45px;
width:830px;
z-index:2;
}
The script is working fine. When I scroll down, the menu float as specified. But I dun wanna the menu to float all the way with scrolling. I need the float of the menu to fire only when I enter specific divs not all the way with scrolling.. Any clues?
is this what look like?
html
<div id="header">HEADER</div>
<div id="content">
<div id="left">LEFT</div>
<div id="right">RIGHT</div>
</div>
<div id="footer">FOOTER</div>
js
$(function() {
var $sidebar = $("#right"),
$window = $(window),
rightOffset = $sidebar.offset(),
rightDelta = $("#footer").offset().top - $("#header").offset().top - $("#header").outerHeight() - $("#right").outerHeight(),
topPadding = 15;
$window.scroll(function() {
$sidebar.stop().animate({
marginTop: Math.max(Math.min($window.scrollTop() - rightOffset.top + topPadding, rightDelta), 0)
});
});
});
working demo
hope this help you
I wrote the script listed in the question.
The script is very versatile and can make div float within a specific area (e.g. another container div). Here are the instructions:
http://www.jtricks.com/javascript/navigation/floating/confined_demo.html
I can't figure out for the life of me what is causing these two errors, any help would be appreciated!

I was using the wrong version of jQuery. I am now using version 1.5.2.
The live function was deprecated in version 1.7. The latest version is 1.9.
Nivo Slider uses the live function. I was running into the same issue as the one stated until I realized our site was grabbing the jQuery code form the web instead of from a .js file living on our site.
I'm using version 1.7.1 and Nivo Slider is working fine now.
The following jquery I am using in my jsp page for adding an autocomplete option to a text field which is having an id mytextfield.
jQuery(function(){
$("#mytextfield").autocomplete("popuppages/listall.jsp");
});
Within the same page, there are some cases in which I will have to remove this autocomplete feature from this text field. ( That is the same field will have to act as a textfield without autocomplete based on the user's inputs to previous fields and options)
Is there any way so that I could remove this newly added 'autocomplete' property from the particular item, that is from $("#mytextfield").
What actually I want to know is is there any option for removing added property
Incase anyone want to refer that autocomplete code, I have attached it below..
;(function($) {
$.fn.extend({
autocomplete: function(urlOrData, options) {
var isUrl = typeof urlOrData == "string";

data: isUrl ? null : urlOrData,
delay: isUrl ? $.Autocompleter.defaults.delay : 10,
max: options && !options.scroll ? 10 : 150
}, options);
// if highlight is set to false, replace it with a do-nothing function
options.highlight = options.highlight || function(value) { return value; };
// if the formatMatch option is not specified, then use formatItem for backwards compatibility
options.formatMatch = options.formatMatch || options.formatItem;

Looks like you are looking for destroy or disable method of autocomplete..
Check Documentation...
destroy
disable
$("#mytextfield").autocomplete( "destroy" )
$("#mytextfield").autocomplete( "disable" )
The difference is after destroy you cannot enable it back...but after disable by using enable you can enable it back..
You can use .removeAttr()
$(target).removeAttr('propertyName');
This will totally remove that property.
But if you want to change any property then use .prop() or .attr()
