Question

I am having some trouble figuring out how to get the number of elements that match a value. Here is my rough code:

var $numElements = $('#casestudy-content article').length;
console.log($numElements);
$('#casestudy-content article').each(function() {
    var $leftElements = $(this).position().left;
    if ( $leftElements === 0 ) {
        console.log($leftElements);
    }
});

So I can count how many elements there are in total. I can find the elements that have a position left of 0… but I do not know how to count those elements that return 0. I need to find how many elements = left: 0; and multiply that by a number. Any suggestions?

Thanks,

You can use filter method.

var len = $('#casestudy-content article').filter(function() {
               return $(this).position().left === 0
          }).length
