Accessors/mutators

Question

I'm trying to create an object like this:

var DadosUtente = true;
var DevolucaoModelo = {
get UtNome() { return (DadosUtente) ? $("#UT_Nome") : $("#Equipamento_Nome")}
};

If i change the DadosUtente the selector returned changes too.

This works properly in Chrome, but when i've tested it with Internet Explorer i get an error because the browsers is excepting :

In the rest of code i'm accessing the selectors like DevolucaoModelo.UtNome.val();

Can someone help me?

By the way, i've search a lot in google and tried others solutions but without success in IE.

Is it JavaScript? JavaScript doesn't have a `get` keyword. http://www.quackit.com/javascript/javascript_reserved_words.cfm — Sanghyun Lee, Jul 15 '11 at 18:15
JavaScript Getters and Setters are not supported in IE; see: http://stackoverflow.com/questions/1077106/javascript-getters-setters-in-ie — Justin Ethier, Jul 15 '11 at 18:16
@Justin Oh, I didn't know about JavaScript Getters and Setters. Thanks for the link. — Sanghyun Lee, Jul 15 '11 at 18:40

Why not try:

var DadosUtente = true;
var DevolucaoModelo = {
    getUtNome : function() { return (DadosUtente) ? $("#UT_Nome") : $("#Equipamento_Nome")}
};

If you don't want to call a function then do it like this:

var DadosUtente = true;
var DevolucaoModelo = {
    UtNome : (DadosUtente) ? $("#UT_Nome") : $("#Equipamento_Nome")
};

Then call it like DevolucaoModelo.UtNome.

Shef

Because i was looking for an alternative solution that doesn't involve to call an function – Gui Jul 15 '11 at 18:18
@guilhermeGeek: Accessors and mutators are functions. Just use a function. It'll save you grief, and there's no reason not to. – Lightness Races in Orbit Jul 15 '11 at 18:28
Shef that way doesn't work because if you change the "DadosUtente" to false, the object will keep returning the $("#UT_Nome") anyway. I'll use functions instead, thanks ;) – Gui Jul 15 '11 at 18:34
@guilhermeGeek: If it should change after the first execution, of course you need the functions. – Shef Jul 15 '11 at 18:36

Yes mate it changes after the first execution. I guess i'm too used to C#, i really need to know better JS. Thank you all the the replies ;) – Gui Jul 15 '11 at 18:39
