Usage

Since the bootstrapValidator plugin requires jQuery and Bootstrap 3, you have to include the required CSS and JS files to your page:

<link rel="stylesheet" href="/path/to/bootstrap/css/bootstrap.css"/>
<link rel="stylesheet" href="/path/to/bootstrapValidator.min.css"/>

<script type="text/javascript" src="/path/to/jquery/jquery-1.10.2.min.js"></script>
<script type="text/javascript" src="/path/to/bootstrap/js/bootstrap.min.js"></script>
<script type="text/javascript" src="/path/to/bootstrapValidator.min.js"></script>

Call the plugin to validate the form as following:

$(document).ready(function() {
    $(<form Selector>).bootstrapValidator({
        // The default error message for all fields
        // You can specify the error message for any fields
        message: ...,

        // The submit buttons selector
        // These buttons will be disabled when the form input are invalid
        submitButtons: ...,

        // Custom submit handler
        // The handler has two arguments
        // - validator is the instance of BootstrapValidator
        // - form is jQuery object representing the current form
        // By default, submitHandler is null
        submitHandler: function(validator, form) {
        },

        // Live validating. Can be one of 3 values:
        // - enabled: The plugin validates fields as soon as they are changed
        // - disabled: Disable the live validating. The error messages are only shown after the form is submitted
        // - submitted: The live validating is enabled after the form is submitted
        live: 'enabled',

        // The fields which need to be validated
        fields: {
            ...
            // The field name
            <fieldName>: {
                // The default error message for this field
                message: ...,

                // Array of validators
                validators: {
                    ...
                    <validatorName>: <validatorOptions>
                    ...
                }
            }
            ...
        }
    });
});

Build

BootstrapValidator uses grunt to simplify building process.

From the BootstrapValidator root directory, execute the following commands to install the dependent packages (the administrator permission might be required):

$ npm install grunt --save-dev
$ npm install grunt-contrib-concat --save-dev
$ npm install grunt-contrib-copy --save-dev
$ npm install grunt-contrib-cssmin --save-dev
$ npm install grunt-contrib-uglify --save-dev
$ npm install grunt-contrib-watch --save-dev

Then, uses grunt to build:

$ grunt

If you want grunt to generate scripts whenever the original scripts (located in src) change, use the following command:

$ grunt watch

The generated scripts (including source and compressed versions) are placed inside the dist directory.
