React bootstrap custom form validation
Comentaris, suggeriments i peticions de tracci? s?n benvinguts! Exemple 1: la importaci? del formulari de registre simple Reacciona des de 'reaccionar'; importa { ButtonInput } des de 'react-bootstrap'; Importa el formulari i els components validats. Tingueu en compte que heu d' usar // aquest component ValidatedInput en comptes de l' original per tenir // validaci? i altres caracter?stiques que treballen import { Formulari, ValidatEdInput } des de 'react-bootstrap-validation'; Tamb? hi ha un embolcall per a entrades de r?dio que reaccionen-bootstrap // no (encara) tenen importaci? { R?dio, RadioGroup } de 'react-bootstrap-validation'; classe MyRegistrationForm s'est?n ponent { ... render() { retorn ( <Form supply= callbacks= to= both= valid= and= invalid= submit= attempts= onvalidsubmit={this._handleValidSubmit.bind(this)} oninvalidsubmit={this._handleInvalidSubmit.bind(this)}><ValidatedInput type='text' label='Email' each= input= that= you= need= validated= should= have= the= name= prop= name='email' validation= rules= separated= with= comma= validate='required,isEmail' error= messages= for= each= error= type= errorhelp={{ required:= 'please= enter= your= email',= isemail:= 'email= is= invalid'= }}=></ValidatedInput> <ValidatedInput type='password' name='password' label='Password' you= can= pass= params= to= validation= rules= validate='required,isLength:6:60' errorhelp={{ required:= 'please= specify= a= password',= islength:= 'password= must= be= at= least= 6= characters'= }}=></ValidatedInput> <ValidatedInput type='password' name='password-confirm' label='Confirm Password' validate= can= be= a= function= as= well= validate={(val , context)=>val === context.password} // Si errorAjuda la propietat ?s una cadena, llavors s'utilitza // per a tots els errors de validaci? possibles ErrorAjuda='Les contrasenyes no coincideixen' /> {/* Component personalitzat per subministrar un parell d'embolcalls d'arrencada al voltant d'entrades de r?dio per semblar bonic */} <RadioGroup name='radio' value='3' label='Which one is better?' supports= validation= as= well= validate={v ==>v === 'cola'} errorHelp='Pepsi? Seriosament?' // I accepta (gaireb?) tots els mateixos accessoris // com altres components de react-bootstrap labelClassName='col-xs-2' wrapperClassName='col-xs-10'> {/* R?dio <Radio value='cola' label='Cola'></Radio> <Radio value='pepsi' label='Pepsi'></Radio> ?s un embolcall simple al voltant del component d'entrada de react-bootstrap */}</RadioGroup> <ValidatedInput type='checkbox' name='agree' label='I agree to the terms and conditions' validation= rules= is= easily= extendable= to= fit= your= needs.= there= are= only= two= custom= rules,= 'ischecked'= and= 'required',= others= are= stock= validator.js= methods= validate='isChecked'></ValidatedInput> <ButtonInput type='submit' bssize='large' bsstyle='primary' </ValidatedInput></Form> ); } _handleValidSubmit(values) { // Values is an object that contains all the values // of the entries } _handleInvalidSubmit(errors, values) { // Errors is an array containing input names // that could not validate } ... } Example 2: Validating with the schema In case you have an external validation scheme, there are a couple of methods that allow you to use it. Note the following example revalidator: ... revalidator amount of 'revalidator'; Simple revalidation scheme with two fields allow schema = { properties: { email: { type: 'string', maxLength: 255, format: 'email', required: true, allowEmpty: false }, password: { type: 'string', minLength: 8, maxLength: 60, required: true, allowEmpty: false } }} } } Class MyLoginForm extends ponent { ... render() { return ( <Form provide= a= validation= method= for= the= whole= form= values= object.= this= way= inputs= will= only= be= validated= upon= submit.= validateall={this._validateForm.bind(this)} onvalidsubmit={this._onSubmit.bind(this)}><ValidatedInput type='text' label='Email' name='email' errorhelp='Email address is invalid'></ValidatedInput> <ValidatedInput type='password' name='password' label='Password' errorhelp='Password is invalid'></ValidatedInput> ... </Form> ); } _validateForm(values) { let res = revalidator.validate(values, schema); // If the values passed validation, let's return true if (res.valid) { return true; } // Otherwise we should return an object
containing errors // e.g. { email: true, password: true } return res.errors.reduce((errors, error) => { // Set each property in truth error description errors or // a string[error.property] = true; return errors; }, {}); Component Form is a wrapper around all entries. Properties aValidSubmit: Callback required function that receives value object, which is an input hash mapName => inputValue. <Form onvalidsubmit={values ==> alert('Hello ${values.name}!')} > <ValidatedInput name=name></ValidatedInput> ... </Form> onInvalidSubmit: Callback function called when there was form and form submission event did not pass validation. Receives two parameters: errors: Array and values: Object. <Form onvalidsubmit={values ==> alert('Hello ${values.name}!')} onInvalidSubmit={(errors, values) => { alert('The following fields are invalid: ${errors.join(', ')}'); }} > <ValidatedInput name=firstName validate=required></ValidatedInput> <ValidatedInput name=lastName validate=required></ValidatedInput> ... </Form> Model: The object accepts a hash map of the initial form values. <Form onvalidsubmit={values ==> alert('Hello ${values.name}}')} model={{ firstName: 'Jon', lastName: 'Snow' }}> <ValidatedInput name=firstName validate=required></ValidatedInput> <ValidatedInput name=lastName validate=required></ValidatedInput> ... </Form> validateOne: Function If present, this response is called when the field should be revalidated, either when the form is submitted or the entry onChange event is dismissed. Receives the following arguments: inputName: String, inputValue: String| Boolean| List of files and context: Object. The result is expected in the same format as in the validated response of Useful for validation with external schema. valideInput function(name, value, context) { yes (! SomeExternalSchema.validate(name, value, context)) { return ''; } return true; } ... <Form onvalidsubmit={this._onSubmit.bind(this)} validateone={validateInput}> ... </Form> Validate All: Function If present, this response is called instead of field by field Receives an argument: values: Object. It should become true if the data is validated correctly, otherwise fieldname map hash errors => errorText. If no specific error text is available, boolean truth is allowed instead of aText string error. <Form onvalidsubmit={this._onSubmit.bind(this)} validateall={values ==> { // Force validation error, returns the error object. returns the object of errors. returns { email: true, firstName: 'Invalid name' }; }} > ... </Form> errorHelp: String| Object When validation error is triggered and there is no errorHelp property specified for the validated entry, the error text is searched in the form error propertyHelp. validationEvent: String input event that activates field validation. It can be an onChange, onBlur or onFocus. The default value is in Change. ValidatedInput An extension of the react-bootstrap input component. It should be used instead of the original for all fields to validate. All validated returns must have the name property set. Property Name: Required String This property is inherited from the entry with only the difference required for ValidatedInput. validationEvent: Chain event that activates validation. It can be an onChange, onBlur or onFocus. The default value is in Change. Replaces the validation of the event's Sales form. <ValidatedInput name='email' validationevent='onBlur' validate='required,isEmail'></ValidatedInput> validate: Function| String Either a validation function or a string validation rule. The validation function receives two arguments, voucher and context. The first is the value of the entry, the second is an object, which contains values of all form fields. Having context is useful if you have a field, validation depends on other values on the form. <ValidatedInput name='passwordConfirm' validate={(val, context)=> { return val === context.password; }} /> The result of the function must be a Boolean or a string. Any returned value that !== true is considered an error. If the string is returned, the errorHelp property is used to render the error. The validation rule is a combination of .js methods separated with comma. <ValidatedInput name='email' validate='required,isEmail,isLength:5:60'></ValidatedInput> In the example above, the value of the entry will be validated with three methods. Reverse rules (such as !isNull) are supported, although by mistakeHelp object are searched without the exclamation mark. ErrorHelp: Object| String can be a string with error text or an object with map ruleName => errorText. <ValidatedInput name=email validate='required,isEmail' ,= errorhelp={{ required:= 'please= enter= your= email',= isemail:= 'invalid= email'= }}=></ValidatedInput> If the errorhelp property is omitted, the default messages are searched from errorHelp The component Radio is basically the same as ValidatedInput, except that it cannot be validated. Validation is performed on RadioGroup. RadioGroup wrapping component for Radio elements that performs validation and easy </ValidatedInput> </ValidatedInput> value settings. Following properties are inherited from original react-bootstrap entry: standalone, hasFeedback, bsSize, bsStyle, groupClassName, wrapperClassName, labelClassName <RadioGroup name='radio' set= the= initial= value= value='1' label='Some random options' labelclassname='col-xs-2' wrapperclassname='col-xs-10'> <Radio value='1' label='Option 1'></Radio> <Radio value='2' label='Option 2'></Radio> <Radio value='3' label='Option 3'> ;</Radio> </RadioGroup> And the following are from ValidatedInput: validate, errorHelp validationEvent: String This property is a little different from ValidatedInputs one - only accepts onChange (which is also default) and should not be used. Validator Validator A validator.js an extended object with the following custom validation methods: Validator.required(val: String) Returns true (if the value is not null. It can be used as aliases in the validation rule !isNull. Validator.isChecked(voucher: String) Used only for checkboxes, since their value is returned as Boolean by the Form component. Returns true if the value is equal to 'true'. This is because all the values that come to .js methods are treated as strings. Refer to .js validator documentation for more information on validation methods and how to expand it. FileValidator An object similar to the validator.js with the extend(name, func) method and full of file validation help. This validator is used for all [type=file] entries in the form. Each validation method accepts the FileList object as a file param. import { FileValidator } from 'react-bootstrap-validation'; ... <ValidatedInput ref=file name=file type='file' label='Attachments' multiple= validate={files ==> { if (FileValidator.isEmpty(files)) { return 'Please select a file'; } if (! FileValidator.isFilesCount(rows, 1, 3)) { return 'You cannot select more than 3 files'; } yes (! FileValidator.isTotalSize(files, 1048576)) { return 'Total size must be at least 1MB'; } yes (! FileValidator.isEachFileSize(files, 0, 1048576)) { return 'Each file must not be greater than 1MB'; } if (FileValidator.isExtension(files, [ 'exe', 'cmd', 'bat', 'com', 'vbs', 'vbe', 'js', 'jse', 'wsf', 'wsh', 'msc' ])) { return 'Executable files are not allowed'; } return true; }} /> Available methods: FileValidator.isEmpty(rows: FileList) Returns true (if there are no files in the file list). FileValidator.isSingle(rows: FileList) Returns true if the file count is equal to 1. FileValidator.isMultiple(rows: FileList) Returns true if the file count is greater than 1. FileValidator.isFilesCount(rows: FileList, min: Number, [max: Number]) Returns true if files count is within allowed range. If the maximum is not supplied, check if the file count is equal to min. FileList, min: Number, [max: Number]) Retorna true if total size of all files is within allowed range. FileValidator.isEachFileSize(files: FileList, min: Number, [max: Number]) Retorna true (si la mida de cada fitxer est? dins del rang perm?s. FileValidator.isExtension(fitxers: FileList, </ValidatedInput> </ValidatedInput> Array) Returns true if the extension of each file is in the extension array. FileValidator.isType(rows: FileList, types: Array) Returns true (fileValidator.isType) (files: File list, type: Array) Returns true (if the MIME type of each file is in the type array. The tests are written using the Jest unit's testing framework for Facebook. run the tests simply use the npm test command. All tests must be compiled and passed before accepting a traction request. For new features, add a new drive test specification to the test directory. Contributions for existing test specifications are welcome.
