    If you are not familiar with regular expressions, you may feel that description very strange. And matter of fact, it is a strange description for those unfamiliar with formal languages. If your regular expression can not interpret the intended syntax and semantics, you can use an online tester.

    Validate input data

    The pattern attribute of AutoConnectInput only determines the data consistency on the web browser based on the given regular expression. In order to guarantee the validity of input data, it is necessary to verify it before actually using it.

    +

    You can validate input data from AutoConnectInput using the isValid function before actually processing it. The isValid function determines whether the value currently stored in AutoConnectInput matches the pattern.

    Convert data to actually type

    The values in the AutoConnectElements field of the custom Web page are all typed as String. A sketch needs to be converted to an actual data type if the data type required for sketch processing is not a String type. For the typical data type conversion method, refer to section Tips for data conversion.

You can specify the direction to arrange the radio buttons as AutoConnectRadio vertically or horizontally. This basic layout depends on the CSS of the AutoConnect menu so you can not change drastically. Form and AutoConnectElements \u00b6 All AutoConnectElements placed on custom web pages will be contained into one form. Its form is fixed and created by AutoConnect. The form value (usually the text or checkbox you entered) is sent by AutoConnectSubmit using the POST method with HTTP. The post method sends the actual form data which is a query string whose contents are the name and value of AutoConnectElements. You can retrieve the value for the parameter with the sketch from the query string with ESP8266WebServer::arg function or PageArgument class of the AutoConnect::on handler when the form is submitted. AutoConnectElement - A basic class of elements \u00b6 AutoConnectElement is a base class for other element classes and has common attributes for all elements. It can also be used as a variant of each element. The following items are attributes that AutoConnectElement has and are common to other elements. Sample AutoConnectElement element(\"element\", \"
    \"); On the page: Constructor \u00b6 AutoConnectElement( const char * name, const char * value) name \u00b6 Each element has a name. The name is the String data type. You can identify each element by the name to access it with sketches. value \u00b6 The value is the string which is a source to generate an HTML code. Characteristics of Value vary depending on the element. The value of AutoConnectElement is native HTML code. A string of value is output as HTML as it is. type \u00b6 The type indicates the type of the element and represented as the ACElement_t enumeration type in the sketch. Since AutoConnectElement also acts as a variant of other elements, it can be applied to handle elements collectively. At that time, the type can be referred to by the typeOf() function. The following example changes the font color of all AutoConnectText elements of a custom Web page to gray. AutoConnectAux customPage; AutoConnectElementVT & elements = customPage.getElements(); for (AutoConnectElement & elm : elements) { if (elm.typeOf() == AC_Text) { AutoConnectText & text = reinterpret_cast < AutoConnectText &> (elm); text.style = \"color:gray;\" ; } } The enumerators for ACElement_t are as follows: AutoConnectButton: AC_Button AutoConnectCheckbox: AC_Checkbox AutoConnectElement: AC_Element AutoConnectInput: AC_Input AutoConnectRadio: AC_Radio AutoConnectSelect: AC_Select AutoConnectSubmit: AC_Submit AutoConnectText: AC_Text Uninitialized element: AC_Unknown Furthermore, to convert an entity that is not an AutoConnectElement to its native type, you must re-interpret that type with c++. AutoConnectButton \u00b6 AutoConnectButton generates an HTML < button type = \"button\" > tag and locates a clickable button to a custom Web page. Currently AutoConnectButton corresponds only to name, value, an onclick attribute of HTML button tag. An onclick attribute is generated from an action member variable of the AutoConnectButton, which is mostly used with a JavaScript to activate a script. Sample AutoConnectButton button(\"button\", \"OK\", \"myFunction()\"); On the page: Constructor \u00b6 AutoConnectButton( const char * name, const char * value, const String & action) name \u00b6 It is the name of the AutoConnectButton element and matches the name attribute of the button tag. It also becomes the parameter name of the query string when submitted. value \u00b6 It becomes a value of the value attribute of an HTML button tag. action \u00b6 action is String data type and is an onclick attribute fire on a mouse click on the element. It is mostly used with a JavaScript to activate a script. 1 For example, the following code defines a custom Web page that copies a content of Text1 to Text2 by clicking Button . const char * scCopyText = R\"( )\" ; ACInput(Text1, \"Text1\" ); ACInput(Text2, \"Text2\" ); ACButton(Button, \"COPY\" , \"CopyText()\" ); ACElement(TextCopy, scCopyText); AutoConnectCheckbox \u00b6 AutoConnectCheckbox generates an HTML < input type = \"checkbox\" > tag and a < label > tag. It places horizontally on a custom Web page by default. Sample AutoConnectCheckbox checkbox(\"checkbox\", \"uniqueapid\", \"Use APID unique\", false); On the page: Constructor \u00b6 AutoConnectCheckbox( const char * name, const char * value, const char * label, const bool checked) name \u00b6 It is the name of the AutoConnectCheckbox element and matches the name attribute of the input tag. It also becomes the parameter name of the query string when submitted. value \u00b6 It becomes a value of the value attribute of an HTML < input type = \"checkbox\" > tag. label \u00b6 A label is an optional string. A label is always arranged on the right side of the checkbox. Specification of a label will generate an HTML

AutoConnectButton : Labeled action button AutoConnectCheckbox : Labeled checkbox AutoConnectElement : General tag AutoConnectInput : Labeled text input box AutoConnectRadio : Labeled radio button AutoConnectSelect : Selection list AutoConnectSubmit : Submit button AutoConnectText : Style attributed text Layout on a custom Web page \u00b6 The elements of the page created by AutoConnectElements are aligned vertically exclude the AutoConnectRadio . You can specify the direction to arrange the radio buttons as AutoConnectRadio vertically or horizontally. This basic layout depends on the CSS of the AutoConnect menu so you can not change drastically. Form and AutoConnectElements \u00b6 All AutoConnectElements placed on custom web pages will be contained into one form. Its form is fixed and created by AutoConnect. The form value (usually the text or checkbox you entered) is sent by AutoConnectSubmit using the POST method with HTTP. The post method sends the actual form data which is a query string whose contents are the name and value of AutoConnectElements. You can retrieve the value for the parameter with the sketch from the query string with ESP8266WebServer::arg function or PageArgument class of the AutoConnect::on handler when the form is submitted. AutoConnectElement - A basic class of elements \u00b6 AutoConnectElement is a base class for other element classes and has common attributes for all elements. It can also be used as a variant of each element. The following items are attributes that AutoConnectElement has and are common to other elements. Sample AutoConnectElement element(\"element\", \"
    \"); On the page: Constructor \u00b6 AutoConnectElement( const char * name, const char * value) name \u00b6 Each element has a name. The name is the String data type. You can identify each element by the name to access it with sketches. value \u00b6 The value is the string which is a source to generate an HTML code. Characteristics of Value vary depending on the element. The value of AutoConnectElement is native HTML code. A string of value is output as HTML as it is. type \u00b6 The type indicates the type of the element and represented as the ACElement_t enumeration type in the sketch. Since AutoConnectElement also acts as a variant of other elements, it can be applied to handle elements collectively. At that time, the type can be referred to by the typeOf() function. The following example changes the font color of all AutoConnectText elements of a custom Web page to gray. AutoConnectAux customPage; AutoConnectElementVT & elements = customPage.getElements(); for (AutoConnectElement & elm : elements) { if (elm.typeOf() == AC_Text) { AutoConnectText & text = reinterpret_cast < AutoConnectText &> (elm); text.style = \"color:gray;\" ; } } The enumerators for ACElement_t are as follows: AutoConnectButton: AC_Button AutoConnectCheckbox: AC_Checkbox AutoConnectElement: AC_Element AutoConnectInput: AC_Input AutoConnectRadio: AC_Radio AutoConnectSelect: AC_Select AutoConnectSubmit: AC_Submit AutoConnectText: AC_Text Uninitialized element: AC_Unknown Furthermore, to convert an entity that is not an AutoConnectElement to its native type, you must re-interpret that type with c++. AutoConnectButton \u00b6 AutoConnectButton generates an HTML < button type = \"button\" > tag and locates a clickable button to a custom Web page. Currently AutoConnectButton corresponds only to name, value, an onclick attribute of HTML button tag. An onclick attribute is generated from an action member variable of the AutoConnectButton, which is mostly used with a JavaScript to activate a script. Sample AutoConnectButton button(\"button\", \"OK\", \"myFunction()\"); On the page: Constructor \u00b6 AutoConnectButton( const char * name, const char * value, const String & action) name \u00b6 It is the name of the AutoConnectButton element and matches the name attribute of the button tag. It also becomes the parameter name of the query string when submitted. value \u00b6 It becomes a value of the value attribute of an HTML button tag. action \u00b6 action is String data type and is an onclick attribute fire on a mouse click on the element. It is mostly used with a JavaScript to activate a script. 1 For example, the following code defines a custom Web page that copies a content of Text1 to Text2 by clicking Button . const char * scCopyText = R\"( )\" ; ACInput(Text1, \"Text1\" ); ACInput(Text2, \"Text2\" ); ACButton(Button, \"COPY\" , \"CopyText()\" ); ACElement(TextCopy, scCopyText); AutoConnectCheckbox \u00b6 AutoConnectCheckbox generates an HTML < input type = \"checkbox\" > tag and a < label > tag. It places horizontally on a custom Web page by default. Sample AutoConnectCheckbox checkbox(\"checkbox\", \"uniqueapid\", \"Use APID unique\", false); On the page: Constructor \u00b6 AutoConnectCheckbox( const char * name, const char * value, const char * label, const bool checked) name \u00b6 It is the name of the AutoConnectCheckbox element and matches the name attribute of the input tag. It also becomes the parameter name of the query string when submitted. value \u00b6 It becomes a value of the value attribute of an HTML < input type = \"checkbox\" > tag. label \u00b6 A label is an optional string. A label is always arranged on the right side of the checkbox. Specification of a label will generate an HTML
  • tag generated from the title and uri member variable of the AutoConnectAux object to the menu list of AutoConnect's built-in HTML. Therefore, the legacy sketches can invoke the web pages from the AutoConnect menu with just declaration the title and URI to AutoConnectAux. Place the item for the legacy sketches on the menu \u00b6 To implement this with your sketch, use only the AutoConnectAux constructed with the title and URI of that page. AutoConnectElements is not required. The AutoConnect library package contains an example sketch for ESP8266WebServer known as FSBrowser. Its example is a sample implementation that supports AutoConnect without changing the structure of the original FSBrowser and has the menu item for Edit and List . The changes I made to adapt the FSBrowser to the AutoConnect menu are slight as follows: Add AutoConnect declaration. Add the menu item named \" Edit \" and \" List \" of AutoConnectAux as each page. Replace the instance of ESP8266WebServer to AutoConnect. Change the menu title to FSBrowser using AutoConnectConfig::title . Join the legacy pages to AutoConnect declared at step #1 using AutoConnect::join . Joining multiple at one time with the list initialization for std::vector .
