Chromium HTML5 新的 Input 类型email对应c++
一、Input 类型: email
email 类型用于应该包含 e-mail 地址的输入域。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>test</title>
</head>
<body><form action="demo-form.php">E-mail: <input type="email" name="usremail"><input type="submit">
</form><p><b>注意:</b> Internet Explorer 9 及更早 IE 版本不支持 type="email" 。</p></body>
</html>二、c++定义：
third_party\blink\renderer\core\html\forms\email_input_type.h
third_party\blink\renderer\core\html\forms\email_input_type.cc
namespace blink {class EmailInputType final : public BaseTextInputType {public:explicit EmailInputType(HTMLInputElement&);// They are public for unit testing.CORE_EXPORT static String ConvertEmailAddressToASCII(const ScriptRegexp&,const String&);CORE_EXPORT static bool IsValidEmailAddress(const ScriptRegexp&,const String&);CORE_EXPORT static ScriptRegexp* CreateEmailRegexp(v8::Isolate* isolate);static Vector<String> ParseMultipleValues(const String& value);bool TypeMismatchFor(const String&) const;private:void CountUsage() override;bool TypeMismatch() const override;String TypeMismatchText() const override;bool SupportsSelectionAPI() const override;String SanitizeValue(const String&) const override;String ConvertFromVisibleValue(const String&) const override;String VisibleValue() const override;void MultipleAttributeChanged() override;String ConvertEmailAddressToUnicode(const String&) const;String FindInvalidAddress(const String&) const;
};template <>
struct DowncastTraits<EmailInputType> {static bool AllowFrom(const InputType& type) {return type.IsEmailInputType();}
};} // namespace blink
