Question

I am trying to create an array from a number of div id’s. Here is my code:

$(function(){
    $('#content > div[id^=post]').each(function(){
        var ele = Number($(this).attr('id').substr(5,4));
        var arr = $.makeArray(ele);
    });
});

I have a list of numbers in my ele variable and I want to join these numbers into one array. Any ideas?

Answer 1

var arr = $('#content > div[id^="post"]').map(function(){
    return Number($(this).attr('id').substr(5,4));
}).toArray();
