The jQuery Validation Plugin provides drop-in validation for your existing forms, while making all kinds of customizations to fit your application really easy.
## Getting Started
### Downloading the prebuilt files
Prebuilt files can be downloaded from https://jqueryvalidation.org/
### Downloading the latest changes
The unreleased development files can be obtained by:
1. [Downloading](https://github.com/jquery-validation/jquery-validation/archive/master.zip) or Forking this repository
2. [Setup the build](CONTRIBUTING.md#build-setup)
3. Run `grunt` to create the built files in the "dist" directory
### Including it on your page
Include jQuery and the plugin on a page. Then select a form to validate and call the `validate` method.
```html
```
Alternatively include jQuery and the plugin via requirejs in your module.
```js
define(["jquery", "jquery.validate"], function( $ ) {
$("form").validate();
});
```

## Reporting issues and contributing code
See the [Contributing Guidelines](CONTRIBUTING.md) for details.
**IMPORTANT NOTE ABOUT EMAIL VALIDATION**. As of version 1.12.0 this plugin is using the same regular expression that the [HTML5 specification suggests for browsers to use](https://html.spec.whatwg.org/multipage/forms.html#valid-e-mail-address). We will follow their lead and use the same check. If you think the specification is wrong, please report the issue to them. If you have different requirements, consider [using a custom method](https://jqueryvalidation.org/jQuery.validator.addMethod/).
In case you need to adjust the built-in validation regular expression patterns, please [follow the documentation](https://jqueryvalidation.org/jQuery.validator.methods/).
**IMPORTANT NOTE ABOUT REQUIRED METHOD**. As of version 1.14.0 this plugin stops trimming white spaces from the value of the attached element. If you want to achieve the same result, you can use the [`normalizer`](https://jqueryvalidation.org/normalizer/) that can be used to transform the value of an element before validation. This feature was available since `v1.15.0`. In other words, you can do something like this:
``` js
$("#myForm").validate({
rules: {
username: {
required: true,
// Using the normalizer to trim the value of the element
// before validating it.
//
// The value of `this` inside the `normalizer` is the corresponding
// DOMElement. In this example, `this` references the `username` element.
normalizer: function(value) {
return $.trim(value);
}
}
}
});
```
## Accessibility
For an invalid field, the default output for the jQuery Validation Plugin is an error message in a `
