> let inline xSquared x = x*x;; val:Foo * y:Foo -> string end val a : Foo > xSquared a;; val it : string = "82"
Just open prim.
That works on floats, ints, etc., -- any type with a * operator .

You need.
The val() only works on HTML input elements ( input , select , textarea , button ).

I can implement a def with a val where the def takes no arguments:

I would like to know if I can use the following JQuery function on a item id located inside a JQuery Dialog.
$('#idofmyfield').val()
Didn't return anything.

($('#idofmyfield').val()); } });
You may need to adjust your selector id to the markup that is generated.</p> </div> </div>
maybe do this:
$('div.ui-widget-content > #idofmyfield').val.

I have seen conflicting advice on whether the following code is better
def function(): ret_val = 0 if some_condition(): ret_val = 2 else: ret_val = 3 return ret_val
or whether this is better:
def function(): if some_condition(): return 2 else: return ...

Your example often is rewritten as
....
Or use another a return statement in the middle of the function - in particular, if it is an early exit.
An accumulator variable and an explicit return ret_val at the end when coding in Python.

I have an object called ValueBox that I created like this:
function ValueBox(params) { ... $.extend(true, this, $('/* some HTML elements */')); ... var $inputBox = $('input[type=text]', this); ... this.val = function(newValue) { if(typeof newValue == ...

That way { return parseFloat(....
Then call val on that.
JQuery.fn.extend({ val: function(newValue) { if (newValue == null) { return $(this).attr("value"); } elseWhen you call $inputBox.change() , pass it the ValueBox object.

Use
$("textarea[name='desc[]']:eq(" + ....
It has not method val.
The jQuery object will have a val() methodBecause
$("textarea[name='desc[]']").get(index);
is DOM object, not jquery.
Of get(index) and it will return a jQuery object.

Is there a way to easily override jQuery's .val() function?
The reason I want to override it is that I want to add some processing each time a value is set for an element. And I don't want to make another custom value setter, such as .myVal()

Answer Snippets (Read the full thread at stackoverflow):
You can store a reference to the original val function') { // setter invoked, do processing....
Function (new_val) { alert("You set a val! How wonderful!"); this.value = new_val; };
Just make after after the regular jQuery library.
