Clearance
Agnostic, asynchronous, and extensible JavaScript object validation.
Features
Clearance is a powerful, dependency-free validation library that:
- allows you to create and bind unlimited validation rules to an object.
- asynchronously validates your objects.
- works on both the client-side and server-side.
- gives you complete control over your objects during each state (valid/invalid/validated/unvalidated)
Getting Started
Usage
var schema = [
{ name: "username", rules: [ "required", "alpha" ] },
{ name: "password", rules: [ "required", "alphaNumeric" ] },
{ name: "email", rules: [ "required", "email" ] }
];
var clearance = new Clearance( schema );
clearance.validate({
data: [
{ name: "username", value: "jasonbellamy" },
{ name: "password", value: "unic0rn" },
{ name: "email", value: "[email protected]" }
],
// Executed if all of the objects are valid.
valid: function( objects ) {
// objects => [ {...} ]
},
// Executed if there are any invalid objects.
invalid: function( objects ) {
// objects => [ {...} ]
},
// Executed after the objects have been validated.
complete: function( objects ) {
// objects => [ {...} ]
}
});
Examples
- Create a validation rule.
Clearance.setRule( "minimumLength", function( object, set, collection ) {
// object.message - the current message associated with the object being validated.
// object.name - the name of the object being validated.
// object.valid - the current state of the object being validated.
// object.value - the value of the object being validated.
// set.invalid - the method to execute if the object is invalid (optional message).
// set.valid - the method to execute if the object is valid (optional message).
// collection - the collection of objects the object being validated belongs to.
if ( object.value.length < 4 ) {
set.invalid( "This objects value must be at least 4 characters long." );
} else {
set.valid( "Congratulations! This objects value is longer than 4 characters!" );
}
});
- Register a schema.
var schema = [
{
name: "username", // (required) the name of this object.
rules: [ "minimumLength" ], // (required) validation rules for this object.
message: "default message", // (optional) default message for this object.
valid: true // (optional) default state for this object.
value: "default value" // (optional) default value for this object.
}
];
- Validate objects against the schema.
clearance.validate({
data: [
{ name: "username", value: "jab" }
],
valid: function( objects ) {
// ...
},
invalid: function( objects ) {
// objects => [ { name: "username", value: "jab", message: "This objects value must be at least 4 characters long." } ]
},
complete: function( objects ) {
// objects => [ { name: "username", value: "jab", message: "This objects value must be at least 4 characters long." } ]
}
});
