Q. How do I convert from a jQuery object to/from a native javaScript array?
A.
Converting from a jQuery object to a native javaScript array
------------------------------------------------------------
You may not even need to do this. You can use a jQuery object much
like an array. For example:
obj = $('p'); // Get all paragraphs into a jQuery object
for (i = 0; i < obj.length; i++) {
// Do something with obj[i]
}
As you can see, jQuery objects have .length and [].
But, .pop() and .reverse() are missing. And you may want to
pass the array to a function that expects a native array. So do this:
obj = $('p'); // Get all paragraphs
a = $.makeArray(obj); // One way to do it
a = obj.toArray(); // The other way

Converting from a native javaScript array to a jQuery object
------------------------------------------------------------
Just use the jQuery() function.
For example:
var a, obj;
// Make a regular javaScript array
a = new Array();
a.push('one');
a.push('two');
a.push('three');
obj = jQuery(a); // Now you have a jQuery object
