Description

Doesn't work properly in 1.2.6:

var args = [1, 2, 3];

var appendArgs = ["A", false, 10];

$.merge(args, appendArgs);

should return:

[1, 2, 3, "A", false, 10]

returns:

[1, 2, 3, "A"]

This will probably not work in 1.3:

var args = [1, 2, 3];

var appendArgs = ["A", false, null, 10];

$.merge(args, appendArgs);

should return:

[1, 2, 3, "A", false, null, 10]

will probably return:

[1, 2, 3, "A", false]

Shouldn't it be better to use for loop instead while for merge function? Btw, array with null inside is still valid array.

jQuery.merge was mainly intended to merge arrays of DOM objects, although I agree the docs don't put any limits on what can be merged. The easiest "fix" might be to change the documentation. If you're really trying to combine two arrays, just use Array.concat.

I am seeing some problems with jQuery.merge() as well. I am using jQuery 1.3.1 and i use the merge() function to merge arrays of DOM objects. I am getting all the objects in the final result but the array length still reflects the original value prior to the merge.

jbeckton, are they really Javascript Array objects, or are they some sort of nodelist collection? The arguments to merge should be genuine arrays.

I think

jQuery.merge

is working as documented so I'll close this.
