hmmm my page works with firefox, but in internet explorer i always get an “Error: Object expcted” break…

and the script debugger highlights something like this…

<li onclick=”foo(); Element.hide(‘blarg’);> …

@lamdkauthorJan 25.2008 — hmm im kinda of a noob...

foo() is declared alone by itself in a file foo.js

i've never written a class in javascript! do i have to contain it withing something like


var Foo = {

function foo() {

}

}

or something? then i can use Foo.foo()? i think i tried yesterday and i could nt get it to work

?

@KorJan 26.2008 — Javascript [I]has no classes[/I]. javascript is a prototype language, that means it uses functions and methods applied upon objects. An event handler (as onclick) calls a [B]function[/B], not a variable, which is not quite the same.

A function is to be set as

[B]function [/B][COLOR="Navy"]foo()[/COLOR]{

[COLOR="DimGray"]... code inside ...[/COLOR]

}

The way you have written:

[B]var[/B] [COLOR="DarkGreen"]Foo=[/COLOR]{

...

}

you have set an [B]object[/B]. An object needs pairs [B]property:value[/B]

@KorJan 27.2008 — In javascript, as in all the OO (Object Oriented) languages, you must first do a OOA (OO Analysis) and later the OOD (OO Design).

In simple words, you must, first, clarify yourself [I]which[/I] is the nature of the problem and [I]what[/I] the system suppose to do (OOA), and only later you can start thinking [I]how[/I] that aim is to be accomplish (OOD) following the specific language's constrains.

Now, what is your OOA? What do you want to do, after all? Create a new property for an object using a function? What kind of object? Why?

In other words, a surgeon learns first [I]why[/I] he has to cut something and later [I]how[/I] to cut something...
