how can i tell if a javascript function works across browsers

How can I tell if a given javascript function will work across browsers? For instance, I want to use String.trim() and I see that it works in Firefox, but will it work in all the other major browsers? I imagine there is a good doc online somewhere, but I can't find it.

QuirksMode can give you information but mostly about CSS and DOM.

String.prototype.trim is a new method, from the ECMAScript 5th Edition Standard.

To check the availability of the new ES5 methods on various browsers, give a look to the following table:

Usually if you are checking which built-in standard methods are available and work propertly across browsers, you can run conformance tests:

The book Dynamic HTML The Definitive Reference by Danny Goodman is a huge help for this type of research.

For example, for the function String.replace(), it tells me it is supported by the following browsers and versions (since): IE 4, NN 4, Moz all, Saf all, Op 7, and has been included in ECMA 3.

Check out the W3Schools JavaScript site, especially the complete references for the various objects. As an example, here's the complete String reference.
