Asqatasun v4 - RGAA 3.2016 - Rule 6.1.3

Summary

This test consists in checking whether the context of each combined link is enough explicit to understand the purpose and the target

Business description

Criterion

6.1

Test

6.1.3

Description

Chaque lien composite vérifie-t-il une de ces conditions (hors cas particuliers) ?

Level

A

Technical description

Scope

Page

Decision level

Semi-Decidable

Algorithm

Selection

Set1

All the <a> tags with a "href" attribute, with children (a[href]:has(*) )

Set2

All the elements of Set1 with own text or with more than 1 child or with only one child not of type <img>, <canvas>, <svg>, <object> (where "img , object[type^=image], object[data^=data:image], object[data$=png], object[data$=jpeg], object[data$=jpg],object[data$=bmp], object[data$=gif], canvas, svg" returns empty)

Set3

All the elements of Set2 with a not empty text and without context (assuming the definition of a link context in Rgaa3.0)

Set4

All the elements of Set2 with a not empty text, with a context (assuming the definition of a link context in Rgaa3.0)

in other words :

size(Set2) = size(Set3) + size(Set4)

Process

Test1

For each element of Set3, we check whether the link content is not pertinent (see Notes about relevancy detection)

For each element returning true in Test1, raise a MessageA, raise a MessageB instead

Test2

For each element of Set4, we check whether the link content is not pertinent (see Notes about relevancy detection)

For each element returning true in Test2, raise a MessageC, raise a MessageD instead

MessageA : Unexplicit Link
MessageB : Check link without context pertinence
MessageC : Unexplicit Link With context
MessageD : Check link with context pertinence

Analysis

Not Applicable

The page has no combined link (Set2 is empty)

Failed

At least one combined link without context has a text content which is blacklisted or only composed of non-alphanumerical characters (Test1 returns false for at least one element)

Pre-qualified

In all other cases

Notes

All the links that have children different from <img>, <object>, <canvas>, or <svg> are considered as combined links.
