Document this fact and also be clear about the fact that merge() is a generic function while unique() really works just with jQuery objects. --- diff --git a/src/jquery/jquery.js b/src/jquery/jquery.js index f40318b5d..5c9dcf3bd 100644 --- a/src/jquery/jquery.js +++ b/src/jquery/jquery.js @@ -1644,24 +1644,16 @@ jQuery.extend({ }, /** - * Merge two arrays together, removing all duplicates. - * - * The result is the altered first argument with - * the unique elements from the second array added. + * Merge two arrays together by concatenating them. * * @example $.merge( [0,1,2], [2,3,4] ) - * @result [0,1,2,3,4] - * @desc Merges two arrays, removing the duplicate 2 - * - * @example var array = [3,2,1]; - * $.merge( array, [4,3,2] ) - * @result array == [3,2,1,4] - * @desc Merges two arrays, removing the duplicates 3 and 2 + * @result [0,1,2,2,3,4] + * @desc Merges two arrays. * * @name $.merge * @type Array - * @param Array first The first array to merge, the unique elements of second added. - * @param Array second The second array to merge into the first, unaltered. + * @param Array first The first array to merge, the elements of second are added. + * @param Array second The second array to append to the first, unaltered. * @cat JavaScript */ merge: function(first, second) { @@ -1672,6 +1664,18 @@ jQuery.extend({ return first; }, + /** + * Reduce an array (of jQuery objects only) to its unique elements. + * + * @example $.unique( [x1, x2, x3, x2, x3] ) + * @result [x1, x2, x3] + * @desc Reduces the arrays of jQuery objects to unique elements by removing the duplicates of x2 and x3 + * + * @name $.unique + * @type Array + * @param Array array The array to reduce to its unique jQuery objects. + * @cat JavaScript + */ unique: function(first) { var r = [], num = jQuery.mergeNum++;
