Expand list with slideToggle - javascript

I have an unordered list like this one:
Show the rest
<ul id="myList">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
<li>Item 6</li>
<li>Item 7</li>
<li>Item 8</li>
<li>Item 9</li>
<li>Item 10</li>
</ul>
and this jQuery code:
var list = $('#myList li:gt(4)');
list.hide();
$('a#myList-toggle').click(function() {
list.slideToggle(400);
return false;
});
The problem is that it slides each individual li item, i need to slide the rest of the list, like i would slide the whole list.
How can I do that?

your method didn't work because it would find the height with height: auto.
After a lot of fail and try, I came up with something that works, almost.
Do you have any comment on my code, I would really appreciate it.
And how would I do it, if I want the same link to collapse the list again
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.1/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
var list = $('ul#myList');
var original_height = list.height();
list.css({height:$('#myList li').height()*5});
$('a#myList-toggle').click(function() {
list.animate({height:original_height})
return false;
});
});
</script>
<style type="text/css">
ul#myList {
overflow: hidden;
}
</style>
</head>
<body>
Show the rest
<ul id="myList">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
<li>Item 6</li>
<li>Item 7</li>
<li>Item 8</li>
<li>Item 9</li>
<li>Item 10</li>
</ul>
</body>
</html>

Pretty clumsy solution IMHO, but if it works for you - it works for you...
For the list to collapse and expand by clicking on the same link:
$(document).ready(function() {
var list = $('ul#myList');
var original_height = list.height();
var new_height = $('#myList li').height()*5;
list.css({height:new_height});
$('a#myList-toggle').click(function() {
if( list.height() == original_height ) {
list.animate({height:new_height});
} else {
list.animate({height:original_height});
}
return false;
});
});

Quick & not-so-dirty way: wrap it with a div element and slideToggle('#myList div.wrapper').

You can give a height to UL tag with overflow:hidden. Then you use animation({height:auto}) to show all. Otherwise, you don't have any viable solution.

Whats the problem with simply toggeling the list instead of the elements?
$(function(){
var listheight = $("#mylist").height();
$("a#myList-toggle").toggle(function(){
$("#mylist").slideToggle();
},function(){$("#mylist").animate({height:listheight})});
});

JQuery. apply css to each element with a class using delay

I've just take a look on a lot of answer on stack but nothing seems can work on this.
I'me trying to apply a style to all element of a list li sequentially using delay. The script show just the last item of the list. What's the problem? thanks in advance for your help
$('ul li').each(function(i){
licont = this
setTimeout(function(){
$(licont).css('opacity','1')
},i * 10);
});
li{
opacity:0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>ITEM 1</li>
<li>ITEM 2</li>
<li>ITEM 3</li>
<li>ITEM 4</li>
</ul>
You can pass the current element as a jQuery object as a parameter to setTimeout to reference current jQuery object within .each() when function passed to setTimeout is called
$('ul li').each(function(i) {
setTimeout(function(el) {
el.css('opacity', '1')
}, i * 1000, $(this));
});
li {
opacity: 0;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
<li>ITEM 1</li>
<li>ITEM 2</li>
<li>ITEM 3</li>
<li>ITEM 4</li>
</ul>

JQuery mobile changing element between list

I have two lists and when clicked on one element I want to remove it from this list and add it to a second one.
<div id="ul1">
<ul id="selected">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
<hr />
<div id="ul2">
<ul id="list2">
<li>Item 10</li>
<li>Item 20</li>
<li>Item 30</li>
<li>Item 40</li>
</ul>
</div>
I am not a jQuery dev and I can't have this working properly.
$("#ul1 a").click(function(){
var para1 = this.dataset['para1'];
$(this).closest('li').remove();
add2(para1);
return false;
});
$("#ul2 a").click(function(){
var para1 = this.dataset['para1'];
$(this).closest('li').remove();
add(para1);
return false;
});
function add(p1){
$("#selected").append('<li><a href="" data-para1='+p1+'>'+p1+'</a></li>');
return false;
}
function add2(p1){
$("#list2").append('<li><a href="" data-para1='+p1+'>'+p1+'</a></li>');
return false;
}
I would really appreciate if someone could point out the correct solution to accomplish this.
Here is a demo.
Thanks
Just use appendTo method.
$("#ul1").on('click', 'a', function(){
$(this).closest('li').appendTo('#list2');
return false;
});
$("#ul2").on('click', 'a', function(){
$(this).closest('li').appendTo('#selected');
return false;
});
Have a look at this snippet. It checks the click() event of the anchor inside the li, looks for the li by matching the father of the element.
$(document).ready(function() {
$('#select li a').each(function(index, anchor) {
// Let's add a click listener
$(anchor).click(function(){
// Let's find the father li
$(this).closest('li').appendTo('#append');
});
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="ul1">
<ul id="select">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
<hr />
<div id="ul2">
<ul id="append">
<li>Item 10</li>
<li>Item 20</li>
<li>Item 30</li>
<li>Item 40</li>
</ul>
</div>
Try this way :
$("#ul1 a").click(function(){
var para1 = $(this).closest('li').html()
$(this).closest('li').remove();
add2(para1);
return false;
});
$("#ul2 a").click(function(){
var para1 = $(this).closest('li').html()
$(this).closest('li').remove();
add(para1);
return false;
});
function add(p1){
("#list2").append(p1);
return false;
}
function add2(p1){
$("#list2").append(p1);
return false;
}
try:
function move(ul1,ul2) {
$('body').on('click',ul1+" a", function(){
$(ul2).append($(this).parent('li'));
//$(this).parent('li').remove();
return false;
});
};
move('#selected','#list2');
move('#list2','#selected');

Having problems using $.each and wrapInner() in jQuery Mobile

I'm trying to iterate through a list of elements and wrap them in a link tag. However, my list displays differently than I want to.
Here is what it should look like: http://jsfiddle.net/eMexU/
HTML
<div id="list" data-role="listview">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</div>
Here is what it looks like when I use $.each and wrapInner(): http://jsfiddle.net/zpFDa/1/
HTML
<div id="list" data-role="listview">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</div>
JS
$("#list li").each(function () {
$(this).wrapInner('')
});
The only way to do this, is replacing existing li with new ones and then call .listview('refresh') to apply styles / enhance markup.
Demo
$("#list li").each(function () {
var text = $(this).text();
$(this).replaceWith('<li>' + text + '</li>')
});
$('#list').listview('refresh');

JQuery - How to move a li to another position in the ul? (exchange 2 li's)

What is a cool way to apply this? I need a script that exchange two < li>'s position in an < ul>.
It think that should be possible to achieve. Thanks for your response.
HTML
<div id="awesome">
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
<li>Item 5</li>
</ul>
</div>
Pseudo Javascript (JQuery)
$("#awesome ul li:eq(1)").exchangePostionWith("#awesome ul li:eq(3)");
HTML Result
<div id="awesome">
<ul>
<li>Item 1</li>
<li>Item 4</li>
<li>Item 3</li>
<li>Item 2</li>
<li>Item 5</li>
</ul>
</div>
You can use jQuery's .after() for moving elements around. I cloned one of them so the original can remain as a placeholder. It's like if you wanted to switch variables a and b, you'd need a third temporary variable.
$.fn.exchangePositionWith = function(selector) {
var other = $(selector);
this.after(other.clone());
other.after(this).remove();
};
Now your pseudocode $("#awesome ul li:eq(1)").exchangePositionWith("#awesome ul li:eq(3)"); isn't so pseudo :-)
$("ul li a").click(function () {
$(this).parent().insertBefore('ul li:eq(0)');
});
<ul>
<li><a>a</a></li>
<li><a>b</a></li>
<li><a>c</a></li>
<li><a>d</a></li>
<li><a>e</a></li>
<li><a>f</a></li>
</ul>

jQuery Expanding & Collapsing lists

The code expands and collapses a list in which list items can have sublists. Any ideas to refactor this code - especially the toggling part. Is it necessary to use closures here ?
$(function()
{
$('li:has(ul)')
.click(function(event){
if (this == event.target)
{
var that = this;
$('li:has(ul)').children().filter(':not(:hidden)').parent().each(function(x){
if(this != that)
toggleList(this);
});
toggleList(this);
}
})
.css({cursor:'pointer', 'list-style-image':'url(plus.gif)'})
.children().hide();
$('li:not(:has(ul))').css({cursor: 'default', 'list-style-image':'none'});
});
function toggleList(L)
{
$(L).css('list-style-image', (!$(L).children().is(':hidden')) ? 'url(plus.gif)' : 'url(minus.gif)');
$(L).children().toggle('fast');
}
EDIT:
The script works on the following HTML snippet (source: jQuery in Action). Actually I was trying to extend the script given in the book.
<ul>
<li>Item 1</li>
<li>Item 2</li>
<li>
Item 3
<ul>
<li>Item 3.1</li>
<li>
Item 3.2
<ul>
<li>Item 3.2.1</li>
<li>Item 3.2.2</li>
<li>Item 3.2.3</li>
</ul>
</li>
<li>Item 3.3</li>
</ul>
</li>
<li>
Item 4
<ul>
<li>Item 4.1</li>
<li>
Item 4.2
<ul>
<li>Item 4.2.1</li>
<li>Item 4.2.2</li>
</ul>
</li>
</ul>
</li>
<li>Item 5</li>
</ul>
Your code doesn't work for me in Safari. When I click on a sub-list, the top-list is toggled.
How about:
$(document).ready(function() {
$('li:has(ul)').click(function(event) {
$(this).css('list-style-image', $(this).children().is(':hidden') ? 'url(minus.gif)' : 'url(plus.gif)')
$(this).children().toggle('fast')
return false
})
.css({cursor:'pointer', 'list-style-image':'url(plus.gif)'})
.children().hide()
$('li:not(:has(ul))').click(function(event) { return false })
.css({cursor:'default', 'list-style-image':'none'})
})
