Examples

Using the number validator

// Just check if it's a number
jSuites.validations.number('10'); // Returns true

// Check if it is a number greater than 27
jSuites.validations.number(5, { // Returns false
    constraint: '>',
    reference: 27
});

// Check if the number is not between 11 and 40
jSuites.validations.number(9, { // Returns true
    constraint: 'not between',
    reference: [11, 40]
});

Using the date validator

// Just check if it's a date
jSuites.validations.date('02-14-2000'); // Returns true

// check if it is a date before 01-01-2000
jSuites.validations.date('01-01-2000', { // Returns false
    constraint: '<',
    reference: '01-01-2000'
});

// Check if the date is between 01-01-2010 and 12-31-2020
jSuites.validations.date('07-18-2017', { // Returns true
    constraint: 'between',
    reference: ['01-01-2010', '12-31-2020']
});

Using the text validator

// Just check if it's a text
jSuites.validations.text('it is a text'); // Returns true

// Check if the text contains another text
jSuites.validations.text('It contains?', { // Returns true
    constraint: 'contains',
    reference: 'It contains'
});

// Check if the text is a valid url
jSuites.validations.text('https://jsuites.net', { // Returns true
    constraint: 'url',
});

Using the item list validator

// Check if the item is on the list
jSuites.validations.itemList('8', [1, 2, 4, 8]); // Returns true

Using the general validator

// Check if the number is not between 11 and 40
jSuites.validations(9, { // Returns true
    constraint: 'not between',
    reference: [11, 40],
    type: 'number'
});

Write your own custom validations

It is possible you create and apply custom validation to your cells using JavaScript. The custom method will receive two information, the cell value and the defined configuration, and the method should return if the cell value is valid or not.
/**
 * @param {string} value - The current cell value
 * @param {object} config - The validation definetions
 */
var validation = function(value, config) {

    // Return true when the value is VALID or false when the value is INVALID
    return true;
}
