HTML - Evènement OnKeyPress, Key Press. « Partie précédente | Index | Partie suivante » L'évènement onkeypress est l'une des actions décrivant une frappe sur une touche.
Il est lié aux évènements onkeydown et onkeyup qui à eux trois décrivent complètement la frappe d'une touche du clavier. Taper par exemple la lettre "a" fait intervenir ces trois évènements de façon successive : - le premier évènement déclenché est onkeydown qui correspond à la pression sur la touche - vient ensuite l'évènement onkeypress qui coincide avec le fait d'avoir la touche enfoncée - enfin l'évènement onkeyup relatif au fait de relacher la touche Ces évènements sont régulièrement utilisés pour faire des contrôles sur les saisies des utilisateurs dans les champs textes car il est possible de vérifier les caractères saisis et d'effectuer des traitements en conséquence.
The W3C Markup Validation Service. XML Schema Validator. XML FAQ: Encoding. You will find here the answers to some of the frequently asked questions about character representation in XML and related technologies.
If you find any mistakes or have suggestions for additional useful information, please send an email. What is the default encoding of an XML document? If no encoding declaration is present in the XML document (and no external encoding declaration mechanism such as the HTTP header is available), the assumed encoding of an XML document depends on the presence of the Byte-Order-Mark (BOM). The BOM is a Unicode special marker placed at the top of the file that indicate its encoding.
The BOM is optional for UTF-8. Note that the encoding of an XML document is never iso-8859-1 by default. One of the most common mistake when editing an XML document is to add some extended characters and forget to set the encoding declaration at the top of the document. Which encodings XML parsers support?
