elem as this in function

I have jquery function:

function handleSplittingPrices() {
    var customerId = $(this).val();
    loadSplittingPrices(customerId);
}

I want to execute it with elem as "this":

var elem=$('...');
handleSplittingPrices() <-- here elem will be this

How can I do it?

You're looking for the call method:

handleSplittingPrices.call(elem);

Note that elem is a jQuery object, not a DOM element, so you won't need to call $ inside the function.

Use call:

handleSplittingPrices.call(elem);

You can't. Obviously you don't know what "this" is for.

function handleSplittingPrices(elem) { var customerId = $(elem).val(); loadSplittingPrices(customerId); }

var elem=$('...'); handleSplittingPrices(elem);

Wow. Now wasn't that simpler than trying to define the whole concept of Object Oriented programming?
