Create an array from id's from divs

On my page I've got many div elements which have the same class:

<div class="item" id="lorem">Asdf</div>
<div class="item" id="ipsum">Asdf</div>
<div class="item" id="dolor">Asdf</div>

Now I would like to save the id from every div to an array. It should then look like this:

$array = ["lorem", "ipsum", "dolor"];

How can I do this properly?

Here item is your class name

var x = $('.item').map(function () {
    return this.id;
}).get();
console.log(x);

jQuery.map() function

You can get id of div in array many ways

var IDs = [];
$(".item").each(function(){ IDs.push(this.id); });
console.log(IDs);

or 

var ids = $('.item').map(function(index) {
    return this.id; 
});
console.log(ids);

You can use the each() function of jQuery and iterate over each div to get the id and push it into an array.

var $array = [];
$('div').each(function(){
    var id = $(this).attr('id');
    $array.push(id);
});

Here is a jsFiddle: http://jsfiddle.net/3mokjL6b/2/
