I'd appreciate help on the following problem: Let's say I have a number of ul
elements on a page, each with a number of li
children, eg
<ul>
<li></li>
<li></li>
</ul>
<ul>
<li></li>
<li></li>
<li></li>
</ul>
What would be the best way to find the highest number of children across all ul parents (In the example above, it should return 3 )?
Many thanks, Ch
You just need this:
var high = Math.max.apply(null, $('ul').map(function () {
return $(this).children().length;
}).get());
alert(high);
You can easily check how many li
elements ul
containing by checking length
Try FIDDLE
var highest='0';
$('ul').each(function(){
var elem=$(this).find('li').length;
if(elem >= highest)
highest=elem;
});
alert("Highest no. of li elements is "+highest);
