jQuery.makeArray()
Convert an array-like object into a true JavaScript array.
jQuery.makeArray(obj)🡢 Array
obj
| PlainObject | Any object to turn into a native Array. |
Many methods, both in jQuery and in JavaScript in general, return objects that are array-like. For example, the jQuery factory function $() returns a jQuery object that has many of the properties of an array (a length, the [] array access operator, etc.), but is not exactly the same as an array and lacks some of an array's built-in methods (such as .pop() and .reverse()).
Note that after the conversion, any special features the object had (such as the jQuery methods in our example) will no longer be present. The object is now a plain array.
Turn a collection of HTMLElements into an Array of them.
JS
<div>First</div>
<div>Second</div>
<div>Third</div>
<div>Fourth</div>
CSS
div {
color: red;
}
HTML
// Returns a NodeList
var elems = document.getElementsByTagName("div");
// Convert the NodeList to an Array
var arr = jQuery.makeArray(elems);
// Use an Array method on list of dom elements
arr.reverse();
$(arr).appendTo(document.body);
