function change_width() {
$('#cont').toggle(function(){
$('#cont').animate({marginLeft:'0%'});
},function(){
$('#cont').animate({marginLeft:'18.4%'});
});
}
I have the following code here, and it should work but it doesn't. Instead it's affecting the display attribute, making it display: none. Why is it doing this?

Since toggle(function, function) is deprecated a simple way is toggle a class and check for that class
function change_width() {
var $cont = $('#cont');
$cont.animate({
marginLeft: $cont.hasClass('inset') ? '0%' : '18.4%'
}).toggleClass('inset');
}

For some strange reason this simple click function I've added, which should be adding the 'big' class to the clicked divs, is only working for every other div.
See an example here (click the square boxes with images)
$('.box').click(function(){
$(this).toggleClass('big').siblings().removeClass('big');
});
Here is a fiddle but I chose not to post this as it works fine as it should do. The error is caused by some other element but I don't know what
http://jsfiddle.net/Ly1bxswq/1/

You binding your click handler within a loop, but need to do it only once when all elements added to page.
$.each(data.feed.entry, function (i, entry) {
// ...
$container.append(item);
// ...
})
$('.box').click(function(){
$(this).toggleClass('big').siblings().removeClass('big');
}
As pointed out by #Yan Brunet's comment, it would be much better to delegate the event from every .box to their parent. That way you can bind your handler at any point (even before .box elements are added to page)
$container.on("click", ".box", function(){
$(this).toggleClass('big').siblings().removeClass('big');
});

thanks,
Cfir.

It works for me: http://jsfiddle.net/wy907kbp/4/
$('.test_suite').on('change', function (event) {
console.log($(this).val());
});
You said that want to modify selected value, which you need to explain more.

$(".test_suite").change(function (event) {
val = $(event.target).val()
});

I'm new at javascript and jQuery and I want to use one of those to change my background body images with onclick. Exactly what I want is to create a link with an image so when the people click on it the background body pic will change. Can you help me or give me a simple example.

HTML
<img src="/path/to/image.jpg">Select Image
Javascript
$(document).on('click', 'a.set-background', function(){
$('body').css({
'background' : 'url(' + $(this).find('img').attr('src') + ')'
});
return false;
});

HTML:
<button>Change background</button>
jQuery:
$('button').click(function(){
$('body').css('background-image','image.jpg');
});

Using the code in the above jsfiddle I am unable to unhide and hide a row using jQuery. According to this stack answer it seems I am doing this correctly.
Do I have some stupid error? possibly causing this?
Code:
$('input[name="custom_rejection_option"]').click(function() {
$('.custom_reject_area').toggle(this.checked);
}};

You had a syntax error
$('input[name="custom_rejection_option"]').click(function () {
$('.custom_reject_area').toggle(this.checked);
});
//You had `}` instead of the closing `)`

You just had some typos and things.
$('input[name=custom_rejection_option]').click(function() {
$('.custom_reject_area').toggle(this.checked);
});
