Simple Javascript Validator

This package aims to validate the input data in javascript using the most common validation rules.

This was made with the intention to be used by those who are just practicing using npm packages to their projects (students, beginners, hobbyist, etc.).

Installation

npm install simple-javascript-validator

Validation Rules

Validation	Rule
required	Value must be required
number	Value must be a number
email	Value must be an email
gtzero	Select tag must have a value

gtzero - Because select tag's initial value is zero as shown in the example below:

<select>
  <option value="0" selected="selected">- select -</option>
  <option value="1">Admin</option>
  <option value="2">Guest</option>
</select>

var full_name     = document.getElementById("name").value;
var age           = document.getElementById("age").value;
var email_address = document.getElementById("email_address").value;
