# Validate
[](https://david-dm.org/chemzqm/validate)
[](http://travis-ci.org/chemzqm/validate)
Validate input elements in an easy way [demo](http://chemzqm.github.io/validate/)
* **Design friendly** write html by yourself, no generate html, className change only
* **locale friendly** write error messages in javascript
* **Smart** promise awareness, [invlid](https://github.com/chemzqm/invalid) fileds ignored on `isValid()` call
* **Cache** no validation fired when not changed
* **No harm** no magic, easy to understand
## Install
npm i validate-component
## Usage
``` js
var Validate = require('validate-component')
var validater = Validate(form, {
search: function (el) {
return el.parentNode.firstElementChild.lastElementChild
}
})
validater.on('blur', function (name, val, required, el) {
if (required && !val) return 'Please enter your ' + name
})
validater.on('blur name', function (val) {
if (!/^[\w_]+$/.test(val)) return 'Should only contain letters, numbers and _'
if (val.length < 6) return 'At least have 6 characters'
})
validater.on('blur email', function (val) {
if (!/.+\@.+\..+/.test(val)) return 'Please enter valid email address'
})
form.onsubmit = function(e) {
if (!validater.isValid()) e.preventDefault()
}
```
## API
### Validate.setDefault(opt)
Static method for set default options including:
* `search` Required function for find error element
* `errorClass` ['error'] className add to error element onerror, input element would be add `input-[errorClass]`
* `successClass` ['success'] className add to error element onsuccess, input element would be add `input-[successClass]`
* `successMsg` [''] Optional success message string add to error element, if it's a function, should return message according to input name
### Validate(form, [opt])
Create validate with form element and options (see above).
### .isValid()
Trigger all the blur events for valid fields, return true if all pass (promise results are ignored)
## Events
* `blur` emit with `name` `value` `required` and element, when return string, showed as error message
* `blur [name]` emit with `value` and `element`, when return string, showed as error message
