jQuery using append with effects

Question

How can I use .append() with effects like show('slow')

Having effects on append doesn't seem to work at all, and it give the same result as normal show(). No transitions, no animations.

How can I append one div to another, and have a slideDown or show('slow') effect on it?

Solution 1

Having effects on append won't work because the content the browser displays is updated as soon as the div is appended. So, to combine Mark B's and Steerpike's answers:

Style the div you're appending as hidden before you actually append it. You can do it with inline or external CSS script, or just create the div as

<div id="new_div" style="display: none;"> ... </div>

Then you can chain effects to your append (demo):

$('#new_div').appendTo('#original_div').show('slow');

Or (demo):

var $new = $('#new_div');
$('#original_div').append($new);
$new.show('slow');

Solution 2

The essence is this:

1. You're calling 'append' on the parent
2. but you want to call 'show' on the new child

This works for me:

var new_item = $('<p>hello</p>').hide();
parent.append(new_item);
new_item.show('normal');

or:

$('<p>hello</p>').hide().appendTo(parent).show('normal');

Solution 3

Another way when working with incoming data (like from an ajax call):

var new_div = $(data).hide();
$('#old_div').append(new_div);
new_div.slideDown();

Solution 4

Something like:

$('#test').append('<div id="newdiv">Hello</div>').hide().show('slow');

should do it?

Edit: sorry, mistake in code and took Matt's suggestion on board too.

Solution 5

When you append to the div, hide it and show it with the argument "slow".

$("#img_container").append(first_div).hide().show('slow');

Not sure if that would do what he wants, but if so, you'd chain the functions: $('#divid').append('#newdiv').hide().show('slow').

[Mark Bell]

It does work; the #newdiv bit is wrong though and you're right, you can chain them. I've edited my answer now.

was probably the inline style, adding a css class like "hidden" which equates to display: none is .. "classier" (baddoom tsh) ;)

This won't work. When you use append, it will return the original_div not the newly appended element. So you are actually calling show on the container.

[Matt Ball]

@Vic as it happens .append() doesn't even take a selector string. The idea's still correct though. Thanks, updated.

[Drew Dello Stritto]

The demo works perfectly, but it assumes the content exists - so it won't work if you are generating the content, eg. pulling an image's alt content to create a title or div...

[Chris22]

I've tried both of these ways and it doesn't work. There is no smooth sliding effect on the appended content.

'normal' is not a proper string for speed. leave it blank for no transition (shows up immediately). use string 'fast' for 200ms or 'slow' for 600ms. or type any number like $("element").show(747) (= 747ms) to define own speed. see the docs and look for animation / duration.

[Kevin Grabher]

With slide effect: element.slideUp("slow", function(){ element.appendTo(parent).hide(); element.slideDown(); });

I like keeping the hide part out of the template

[JesuLopez]

The hide and show event applies to the #img_container and not on the first_div, you should use appendTo

This is the best answer one line clean and does what it's supposed to.
