static class functions

[html20009876]

Add 2 static functions in the class:

function ClassCommon()
{
	showNode = function(node,show)
	{
             ...
	}
	moveNode = function(node)
	{
             ...
	}
}

or:

function ClassCommon()
{
	ClassCommon.showNode = function(node,show)
	{
             ...
	}
	ClassCommon.moveNode = function(node)
	{
             ...
	}
}

Which one is correct? (static functions)

Actually, both are not working on my code.

Thanks for corrections.

BTW: use in this way
ClassCommon.showNode(node, true);

ClassCommon doesn't yet exist, as far as I can tell, until the interpretor is outside the definition block. Though not as pretty as in other languages, you can write it like so:

function ClassCommon()
{
}

ClassCommon.showNode = function(node,show)
{
  ...
}

ClassCommon.moveNode = function(node)
{
  ...
}

Hi svidgen,

Thanks, I will test.

But, I like format similar to java or c++.
May class static-function be written inside a class?

Not naturally, no. You'd have to use libraries that let you use a nicer syntax for defining classes. There's no one standardized library I can point you toward. Most of the major libraries -- such as YUI, Closure, and Dojo -- each have their own

Therein lies your problem. JavaScript doesn't have classical inheritance, it has prototypical inheritance, so if you are expecting things to work like Java or C++, you will be disappointed. Even the method described above is not fully equivalent to static methods, it's merely storing a few functions as members of the ClassCommon object, that is the Function object, which you can do for any object.
