How do you pass parameters to called function using ASP.Net Ajax $addHandler

Question

I am trying to use the $addHandler function to add a handler to a text box's click event

var o=$get('myTextBox');
var f = Type.parse('funcWithArgs');
$addHandler(o, 'click', f);

However I need to pass parameters to the called function. How do you do that?

TIA

Answer 1

Wrap your function with an anonymous function (aka lambda):

$addHandler(o, 'click', function() { f(my, arguments, go, here); });

Alternative solution:

If you had a function that created partials, you could do that as well - I use a toolkit that provides for that, and this is how it would be done:

$addHandler(o, 'click', partial(f, my, arguments, go, here));

I don't know (and actually doubt) that Microsoft's framework provides for that, but you could look into writing your own partial function.
