Description: Merge the contents of two arrays together into the first array.
firstThe first array to merge, the elements of second added.
secondThe second array to merge into the first, unaltered.
$.merge() operation forms an array that contains all elements from the two arrays. The orders of items in the arrays are preserved, with items from the second array appended. The
$.merge() function is destructive. It alters the first parameter to add the items from the second.
If you need the original first array, make a copy of it before calling
$.merge() itself can be used for this duplication:
var newArray = $.merge(, oldArray);
This shortcut creates a new, empty array and merges the contents of oldArray into it, effectively cloning the array.
$.makeArray if they are not.
$.merge( [0,1,2], [2,3,4] )
$.merge( [3,2,1], [4,3,2] )
var first = ['a','b','c']; var second = ['d','e','f']; $.merge( $.merge(,first), second);
