Param.js

Validation system, that expects from you some rules (JSON-like-described) and if you want some custom data-type of input-param(s), a validation function for it and/or custom viewer function. If you need custom previewer for your form, you can create a custom template, but usually you can use theme-templates from us. Param.js:

• already supports a lot of data-types, and it's truly rare situation, when you need to add your own;
• works both at the client and at the server-side (node.js);
• was written in pure JavaScript, that makes it compatible with all libraries whatever you want;
• have special editor, that makes creation and modification of rules easy;
• supports params dependencies;
• supports custom data-types;
• supports custom data-properties;
• supports custom validation functions;
• supports theming.

Supported data-types

• integer
• float
• enum
• string
• custom (whatever you want)

All data-types support such limit-properties:

Supported data-properties

• maxlength
• minvalue
• maxvalue
• visibility
• regexp
• default
• dependencies
• required
• readonly
• type
• visibility
• alone
• etc (whatever you want)

Data-dependencies

All properties of params can be dependable on other params. So in pattern (rules for params) you can set them like this:

"param1": {
  "default": "valueOfParam1",
  "dependencies": {
    "dependableParam": [
      {
        "value": "valueOfParam1",
        "properties": [
          ["property", "dependableValue"]
        ]
      }
    ]
  }
}

So this mean that if "param1" have a value like "valueOfParam1", then "dependableParam" should have a value like "dependableValue".
