Element language refers to the language of the form widget ( ) or page ( ) as set by the page author.

UI language refers to the user interface language of the browser or operating system as set by the user. Using the page’s locale will ensure consistency with page-provided data.” Īdditionally, all browsers except Internet Explorer will strip any whitespace characters and thousand separators (space, comma, or period depending on locale - see below) from the value.įollowing this logic we can make a test and get the following web browser support comparison chart: Browser support “Browsers are encouraged to use user interfaces that present numbers according to the conventions of either the locale implied by the input element’s language or the user’s preferred locale. The specification doesn’t define how exactly this should be handled, but suggests the following: However, the value the user inputs or the value that’s displayed to the user doesn’t need to meet this technical requirement. The specification defines the decimal separator as a period regardless of the locale. The value of an must always be either a valid integer (number) or a valid decimal number. This is a big usability as well as a functional problem for web applications. The value presented to the user will still be whatever they typed, but the form will not submit any data. Inputting an invalid value into a will, as per the specification, set the value to an empty string. However, the stored value in memory is always represented with a period. In computing, decimal marks are usually presented in a way following the locale of the system. Roughly half the world uses a comma as their decimal mark, and the other (mainly former colonies of the British Empire) uses a period instead. The problem with these soft keyboards - and even with regular analog keyboards - is the decimal mark. These adaptive soft keyboards are a big convenience to users as they don’t have to manually change the views of their already-hard-to-use keyboard. If an email address is requested for a login, the soft keyboard can be made to include an at sign.įor numeric input, the keyboard can include larger numbers like on a dial-pad, a decimal mark, and a minus sign.

Touch-based software keyboards, or “soft keyboards”, can adapt to the input type that’s requested from the user. (In Latin scripts.) Does your web application take that into consideration? and do web browsers? Over half of the world uses a comma and the other half uses a period as their decimal mark. Not every user can input decimal numbers into the numeric input field without proper localization. An element will open a numeric software keyboard on modern mobile operating systems.
