An array of elements in jQuery

Markup code:

<div id="elements">
    <div>
        <a href="#">text</a>
        <a href="#">text</a>
        <a href="#">text</a>
    </div>
    <div>
        <a href="#">text</a>
        <a href="#">text</a>
        <a href="#">text</a>
    </div>
    <div>
        <a href="#">text</a>
        <a href="#">text</a>
    </div>
</div>

Please tell me how can I get an array of all elements of the div, so that later, it is p开发者_开发知识库ossible to address an array of options?

Such as:

divs[0]  
links[1] 

See https://api.jquery.com/toArray/

$( "li" ).toArray()

This works great in cases like

$( "li" ).toArray().each( function(li) {
  console.log('do something with this list item', li);
})

or if you really want

$( "li" ).toArray()[0]

Demo

var divs = $('#elements div');
var links = $('#elements div a');

1. If you want the DOM elements, then you can access them with the array style like divs[0] or links[2].
2. If you want to get the specific jQuery object, you can access them with divs.eq(0) or links.eq(1).

$('#elements div').eq(0) // first div

$('#elements div a').eq(1) // second anchor in group of divs

Without the .eq() you have a collection of elements, the .eq just singles the elements out.

wrapper = document.getElementById('elements');
divs = wrapper.getElementsByTagName('div');
links = [];
for (i = 0; i < divs.length; i++) {
    links[i] = divs[i].getElementsByTagName('a');
}

divs will now be an array of the divs inside of your "elements" div. Links is now a two dimensional array, where the first index refers to the div inside your "elements" div, and the second index refers to the "a" tags inside that div.

links[2][1]

will refer to the element denoted below:

<div id="elements">
    <div>
        <a href="#">text</a>
        <a href="#">text</a>
        <a href="#">text</a>
    </div>
    <div>
        <a href="#">text</a>
        <a href="#">text</a>
        <a href="#">text</a>
    </div>
    <div>
        <a href="#">text</a>
        <a href="#">text</a>  //this one
    </div>
</div>

Or also, and I believe this is more accurately what you asked for:

$("#elements div:eq(0) a:eq(1)")

$("#elements a")

$("div a")

or $("a")
