http://www.w3.org/Bugs/Public/show_bug.cgi?id=12885 Summary: Add a new input type=numeric Product: HTML WG Version: unspecified Platform: All OS/Version: All Status: NEW Severity: normal Priority: P3 Component: HTML5 spec (editor: Ian Hickson) AssignedTo: ian@hixie.ch ReportedBy: adrianba@microsoft.com QAContact: public-html-bugzilla@w3.org CC: mike@w3.org, public-html-wg-issue-tracking@w3.org, public-html@w3.org HTML5 defines input type=number which allows developers to create an input element for collecting valid real numbers. Input type=number is insufficient for telephone numbers because telephone numbers may have special formatting or allow characters which are not numeric. For this there is a specific telephone input type. There are other cases when developers need to optimize for numeric input but they don't want to require a valid floating point number. A prime example of this is input elements for US zip codes which can have leading zeros and some non-numeric characters. Other use cases for numeric input which may not actually be a real number is a credit card number, passport ID number or product sku number. Webkit already attempts to solve this problem by displaying a numeric keyboard when the developer has set the pattern attribute to "[0-9]*" or "\d*". (Reference: http://developer.apple.com/library/ios/#documentation/StringsTextFonts/Conceptual/TextAndWebiPhoneOS/KeyboardManagement/KeyboardManagement.html#//apple_ref/doc/uid/TP40009542-CH5-SW1) This is a mainstream scenario and developers should have a declarative way to indicate that they want a text field optimized for numeric input. We propose a new input type for this scenario, input type=numeric. This type would be exactly the same as the text and search state (http://dev.w3.org/html5/spec/states-of-the-type-attribute.html#text-state-and-search-state). The difference between the Numeric state and the Text and Search states is that on platforms which support soft keyboards optimized for entering different data types, the Numeric state might result in a soft keyboard optimized for entering numeric digits. The difference between the Numeric state and the number state (http://dev.w3.org/html5/spec/number-state.html#number-state) is that the numeric state does not require that the value be a valid floating point number. It also does not support any of the methods/attributes which depend on the value being a valid number such as valueAsNumber, stepUp and stepDown. Developers can still use the pattern attribute if they want client side validation. -- Configure bugmail: http://www.w3.org/Bugs/Public/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
