JSDValidator

Does for JavaScript what XSD does for XML

JSD stands for Javascript Schema Definition. It defines how a javascript object/variable should be formed. The JSD Validator takes a Javascript object and tests if it's valid according to the schema. It is basically a dimmed down version of what XSD does for XML.

To get started, check out http://www.jsdvalidator.com!

Quick start

• Download JSDValidator from the download-page
• Or Clone a repo: git clone git://github.com/markhomans/JSDValidator.git.
• Place it somewhere in your project and include it in the pages where you want to use it: <script src="JSDValidator-1.4.js"></script>
• Create a schema to validate with. See JSD Schema page for more info.
• Or generate a schema with the online JSD Generator
• Create a Javascript object to validate
• Create a validator instance and validate your object. See JSD Validator page for more info

Quick example

//define the schema to validate with
var jsd_schema =
{
    Type: "Object",
    Attributes: [
    {
      Name: "Name",
      Type: "String"
    },
    {
      Name: "Age",
      Type: "Number"
    },
    {
      Name: "Gender",
      Type: "String",
      Values: [
        "M",
        "F"
      ]
    }
  ]
};

//define the object to validate
var me =
{
    Name: "Mark",
    Age: 30,
    Gender: "M"
};

//instanciate a JSD Validator and set it's schema to the one we created
var jsd_validator = new JSDValidator({Schema: jsd_schema});

//test if the object we created is valid
if(jsd_validator.Validate(me))
{
    //our object is valid!
    console.log('Valid!');
}
else
{
    //our object is not valid :(
    console.log(jsd_validator.Error);
}
