Description
Dans chaque page Web, pour chaque ouverture d'une nouvelle fenêtre effectuée via un lien (attribut target="_blank") ou une commande JavaScript, l'utilisateur est-il averti ?
Level
A
Technical description
Scope
page
Decision level
semidecidable
Algorithm
Selection
Set1
All the <a> tags with an "href" attribute AND a not empty
"target" attribute with a content different from "_self"
(a[href][target]:not([target=_self]):not([target~=^s*$]))
Process
Test1
If Set1 is not empty, raise a MessageA for each occurence.
Raise a MessageB instead.
MessageA : Check user is warned when a new window is opened
- code : CheckUserIsWarnedWhenNewWindowOpen
- status: Pre-Qualified
- parameter : text, title attribute, snippet
- present in source : yes
MessageB : Check whether js prompt eventually a new window
- code : CheckJavaScriptPromptANewWindow
- status: Pre-Qualified
- present in source : no
Analysis
Pre-Qualified
In all cases
Notes
We assume here that a not empty value different from "_self" for the
"target" attribute lead to the opening of the page in a new window. The
detection is not only done with the "_target" value.
On latest webdev data set (2013-10-30, 78,000 pages), the selection has been found on 62039 pages, i.e on 79% of the pages
