jQuery if not first item

JavaScript
1

I have a collection of list items. I want to do something to all but the first one. The below code does not work… sadly…


if(!$('#numericGradesList li:first'))
{
          
}
2

try something like

$('#numericGradesList li:not(:first)').addClass('someclass');

or


$('#numericGradesList li:not(:first)').each(function(){
	$(this).addClass('someclass')
});

Obviously you’d need to change the “addClass” part with whatever you want to do

A jQuery object in a boolean context will always evaluate to true, because it’s an object. If you want to determine if it contains anything then you should check its length property. E.g.


if ( $('something').length > 0 ) {...}

// or:
if ( $('something').length ) {...}

// or:
if ( $('something')[0] ) {...}
