Response structure

The response MUST be in JSON and match with this structure

The distinction of response type it's on the field data or view:

  • If you return a response with the data field, the response was processed as a feedback.
  • If you return a response with the view field, the response was processed as a view
  • If you return a response with the data and view, the response was process as a feedback
Type of response Example Infos
    "type": 	"success",
    "url": 		"yourUrl (optionally entry)",
    "data" : 	{
       "title": 	"yourTitle",
       "message": 	"yourMessage"
   "type": 	"success",
   "url": 	"yourUrl (optionally entry)",
   "view" : "A HTML response"


You have 3 themes available for the alert:

  • Bootstrap 3/4 ( theme-bs.css )
  • Custom ( theme-cust.css )
  • Flat ( theme-flat.css )

You can choose it by including corresponding CSS

Custom settings

Alert message

You can customise the default error message (Unexpected for example)

$( '#yourForm' ).formJS( {
	alerts: {
		unexpected: {
			title:   'Custom unexpected error title',
			message: 'Custom unexpected error message'
		failSend:   {
			title:   'Custom fail send data error title',
			message: 'Custom fail send data error message'
} );


The keys are suffix added after 'formjs' class into alertContainer. Its use for style customisation.

Note: If you change it, you MUST rebuild style with SCSS builder

$( '#yourForm' ).formJS( {
	keys: {
		success: 'success-custom',
		info:    'info-custom',
		warning: 'warning-custom',
		error:   'error-custom'
} );


You can change the icon, set html icon as you want and use icons pack as you want:

  • <i></i> balise
  • <span></span> balise
  • <img /> balise
  • Text also (You need to embrace the text with html balise)
$( '#yourForm' ).formJS( {
	icons: {
		loading: '<span class="fas fa-circle-notch fa-spin"></span>',
		success: '<i class="fas fa-check-square"></i>',
		info:    '<span class="ti-info"></span>',
		warning: '<img src="myIcon.svg" />',
		error:   '<span>ERR</span>'
} );


If you have a custom header request, you can pass into this setting. The url, method and data cannot be modified

Also, you can change the formJS container and submit button identifier.

Note: If you change container, you MUST rebuild style with correct container.

$( '#yourForm' ).formJS( {
	form: {
		ajaxSettings:   {
			async: 		false,
			beforeSend: function (xhr){ 
				xhr.setRequestHeader('Authorization', make_base_auth(username, password)); 
		alertContainer: '.customContainer',
		btnSubmit:      '.myCustomBtnID'
} );


You can redirect the user after an Ajax request. A message will be added after error title.

You can change this message and delay before the redirection

$( '#yourForm' ).formJS( {
	redirection: {
		message: 'Custom redirect message',
		delay:   2500
} );


At the end of precess, a callback is called. You can set. The current alert is passed to function parameter.

$( '#yourForm' ).formJS( {
	callback: function ( currentAlert ) {
		// Do something with currentAlert
} );


You have some event that you can handle:

Event name Params When ?
formjs:submit ajaxSettings: (JsonObject) Options pass to $.ajax() method
ajaxPending: (Boolean) If an ajax request is in progress
At the start of submitting the form and before sending the ajax request
formjs:ajax-success feedback: (JsonObject) Raw data returned by the successful $.ajax() request On the success ajax callback, after the parsing returned data
formjs:error place: (String) The origin of the error
message: (String) The message of the error
data: (Mixed) The additionnal data of the error
When an error occurred during the submit process
formjs:write-alert currentAlert: (JsonObject) The feedback data returned from the ajax request When an alert is rendered on the DOM

For the formjs:error, you can know the origin of the error:

  • AjaxSuccessCallback: An error during the ajax success callback
  • AjaxFailCallback: An error during the ajax fail callback
  • PreSubmit: An error during the submitting process
var $form = $( '#yourForm' ).formJS();
$form.on( 'formjs:write-alert', function ( e, currentAlert ) {
	// Do something with the current alert ...
} );


If you need to use this plugin from the outside of it, you can trigger some event

Event name Params Action
formjs:send-form Start the form sending processing
var $form = $( '#yourForm' ).formJS();
$( '#anotherSendingButton' ).click( function () {
	$form.trigger( 'formjs:send-form' );
} );

Custom style

You have SCSS files to allow you to create custom styles.

In formJSFolder/scss/, you can find _core*.scss files. Use it as the base structure of your custom style.

Create a folder named with theme name and add to file:

  • _variables.scss: Contain YOUR theme variable. It uses to override core variables
  • your-theme-name.scss: Contain all customisation for type of alert: Success, Info, Warning and Error. Use preset from one of existing templates

At the end of customisation, run npm run scss:dist to generate your style css file and minified too.

You must include node_module folder into you sass converter to build a new stylesheet.
