600155 - Let the authors override validation message with x-moz-errormessage attribute

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Mounir Lamouri (:mounir)]

The idea is simple, if an element is invalid and mozErrorMessage is set, the error message will be overwritten by the string in mozErrorMessage. In some way, it lets the authors setting an error message without making the element suffering from a custom validity.

Jonas, should we add an IDL attribute for that? That might be more convenient but that might be annoying for authors if they use it and then we remove it, right?

I would say we should not add an IDL method. Seems better to add minimum amount of code to support an experimental feature.

Why such a very unusual naming for the attribute? Why x- prefix?

It's what HTML5 calls for these days. See towards the end of

x-vendor is terrible. But I'll argue in the W3C bug.

But marking Target Milestone: beta7 because I realized this has been pushed accidentally with a big merge after a backout. I've no idea why :-/
I backed it out and pushed it again to have correct log.
