Is it possible to use a jQuery element object as an array/object key?
Example:
var el = jQuery(this);
var test = {};
test[el] = "something strange";
Doing a:
jQuery.each(test, function(k,v){
console.log(k);
});
just reports [object Object]
Is there a say that I could actually re-use the k as the original jQuery element object?

Answer: Use the jQuery $. map() Method You can simply use the $. map() method to convert a JavaScript object to an array of items.
The $. each() function can be used to iterate over any collection, whether it is an object or an array. In the case of an array, the callback is passed an array index and a corresponding array value each time.
Answer: Use the jQuery. each() function each() or $. each() can be used to seamlessly iterate over any collection, whether it is an object or an array. However, since the $. each() function internally retrieves and uses the length property of the passed array or object.
No, that is not possible.
ECMAscript only allows for strings as key-values for objects.
What you could do instead, is to use the id value from a single node instead. So it might look like
var el = jQuery(this);
var test = {};
test[this.id] = "something strange";
That of course requires the node to have an id value.
