help you fix your problem you need to revoke the native JS DOM Element Object out of the jQuery Object:
code :
alert( e[0].id );
alert( this.id );
alert( e.prop("id") ); /*    this one */
alert( e.get(0).id; ); /* or this one */
alert( e.attr("id") ); /* or this one */
$("#divPlayerActions").children("a").each(function (i, e) {
    alert(e.id); // Cripple // GroundSlam // HealingStar .....
});

PrimeFaces Mobile requests undefined/undefined.css and undefined/undefined.js, causing JSF1064 warning and 404 error

this one helps. This is a bug in PrimeFaces mobile. This was discovered and fleshed out in the following related answer: Why is my p:progressBar not displayed, only the number?
The workaround is, execute this script in end of head or begin of body, either inline or via a custom script file:
code :
var originalPrimeFacesCw = PrimeFaces.cw;
PrimeFaces.cw = function(name, id, options, resource) {
    resource = resource || name.toLowerCase();
    originalPrimeFacesCw.apply(this, [name, id, options, resource]);
};

Hope this helps The second two are the same (though the second one might cause issues on some browsers), but the first is different.
The first one
code :
var arr1 = [undefined, undefined, undefined];
[undefined, undefined, undefined].reduce(function(c) { return c + 1; }, 0);
// 3

[,,].reduce(function(c) { return c + 1; }, 0);
// 0

hope this fix your issue foo has two empty slots not filled with anything (which is resolved to undefined in console). bar is filled with the value of undefined.
So, for example Array.prototype.map is defined to only work when values are set:
code :
foo.map(() => console.log('test'))
// nothing

bar.map(() => console.log('test'))
// test
// test
