I have this HTML:
<ul class="parent">
<ul>
<li>
<ul></ul>
</li>
<li>
<ul>
<li>
<ul></ul>
</li>
</ul>
</li>
</ul>
</ul>
I need to add count classes for all nested lists in this markup, to reach this:
<ul class="parent">
<ul class="level-1">
<li>
<ul class="level-2"></ul>
</li>
<li>
<ul class="level-2">
<li>
<ul class="level-3"></ul>
</li>
</ul>
</li>
</ul>
<ul class="level-1">
<li>
<ul class="level-2"></ul>
</li>
<li>
<ul class="level-2">
<li>
<ul class="level-3"></ul>
</li>
</ul>
</li>
</ul>
</ul>
So i do this:
var parent_ul = $('.parent');
if (parent_ul.doesExist()){
var parent_ul_lists = parent_ul.find('ul');
parent_ul_lists.each(function(){
var i;
for (i = 0; i < parent_ul_lists.length; i++) {
$(this).eq(i).addClass('level-' + i);
}
})
}
But in output i have class test level-1
for all of parent list childrens. Can anybody help?
Try this
$('.parent ul').addClass(function(){
return "level-"+$(this).parents('ul').length;
});
Try this
var parent = $('.parent').children();
next = parent;
var i = 0;
while (next.length) {
parent = next;
parent.addClass("Level_" + i);
i++;
next = next.children();
}
You can use this;
var parent_ul = $('.parent');
var parent_ul_lists = parent_ul.find('ul');
parent_ul_lists.each(function(){
$(this).addClass('level-'+ ($(this).parents().length -1)/2);
});
See working demo here: http://jsfiddle.net/huseyinbabal/qmGcC/
Note: Inspect element in output to see class assigned
You need some good 'ole recursion!
Check out this JSFiddle UPDATE: corrected jsFiddle link
Here is the code:
function labelChildUL(element, count) {
element.children().each(function (index, value) {
var $me = $(value);
if ($me.is("ul")) {
$me.addClass("level-" + (count + 1));
labelChildUL($me, count + 1);
}
else
{
labelChildUL($me, count);
}
});
}
$(document).ready(function () {
var $parent = $('#parent');
labelChildUL($parent, 0);
});
I also updated your html to use id
instead of class
for "parent":
<ul id='parent'>
