jQuery.uniqueSort()
Sorts an array or an array-like object of DOM elements, in place, with the duplicates removed. Note that this only works on arrays/array-likes of DOM elements, not strings or numbers.
jQuery.uniqueSort(array)π‘’ Array
array
ArrayLikeObject The Array or an Array-like object of DOM elements.The $.uniqueSort() function searches through an array or an array-like object of DOM elements, sorting the array/array-like, and removing any duplicate nodes. A node is considered a duplicate if it is the exact same node as one already in the input; two different nodes with identical attributes are not considered to be duplicates. This function only works on plain JavaScript arrays/array-like objects of DOM elements, and is chiefly used internally by jQuery. You probably will never need to use it.
Prior to jQuery 3.0, this method was called jQuery.unique() .
As of jQuery 1.4 the results will always be returned in document order.
Removes any duplicate elements from the array of divs.
JS
<div>There are 6 divs in this document.</div>
<div></div>
<div class="dup"></div>
<div class="dup"></div>
<div class="dup"></div>
<div></div>
CSS
div {
color: blue;
}
HTML
// uniqueSort() must take a native array
var divs = $("div").get();
// Add 3 elements of class dup too (they are divs)
divs = divs.concat($(".dup").get());
$("div")
.eq(1)
.text("Pre-uniqueSort there are " + divs.length + " elements.");
divs = jQuery.uniqueSort(divs);
$("div")
.eq(2)
.text("Post-uniqueSort there are " + divs.length + " elements.")
.css("color", "red");
