FormValidator.js
Javascript data validation library, useful for complex form handling.
The library abstract from user interface aspect, but I write a jquery plugin wrapper to speed up common task.
Features
- Single or multiple rules per field
- Rules as regexp, function or async functions with callback
- No dependency from other framework
- Lightweight (< 2k minified)
- Fully tested (100% code coverage)
How works
The library validate data using rules.
var data = {
name: "Alberto",
age: "34"
}
var rules = {
name: {
rule: /^[a-zA-Z0-9 ,]+$/,
message: "Name must be alphanumeric"
},
age: {
rule: function(value) {
return value > 18;
},
message: "Age must be 18+"
}
}
FormValidator
.validate(data, rules)
.done(function() {
// success
})
.fail(function(errors) {
// fail
})Examples
Basic, wrapped as jquery plugin - /examples/basic.html
$('.form-to-validate').formValidator({
email: {
rule: /^([\w-]+(?:\.[\w-]+)*)@((?:[\w-]+\.)*\w[\w-]{0,66})\.([a-z]{2,6}(?:\.[a-z]{2})?)$/i,
message: "Mail must be valid"
},
age: {
rule: function(value) {
return value >= 18;
},
message: "Age must be 18+"
}
}, {
success: function(e) {
alert('ok!')
}
});Browser Compatibility
