Easy-input-validator NPM

Easy Validator

A jQuery module that validates form fields. You can create your own validations with validator functions, or you can use the ones that are built in.

You can install via npm, yarn, bower, etc.

npm install easy-input-validator

Clone this repository or simply download either js/easy-validator.js or js/easy-validator.min.js.
- Note: easy-validator.min.js is a minified version of js/easy-validator.js. This means that it is a smaller file. If you want to update the scripts contents, then copy js/easy-validator.js. Otherwise, download the minified version.
Include the file in your project

<script src="your/path/to/easy-validator.min.js"></script>

You must simply add the validation name to the class of the input you want to validate.

Custom Validation Demo

<script>
    EasyValidator.add("validate-selection", "That is impossible.", function(val) {
        return val !== "Other";
    })
</script>

You can create custom validations by using the easy-validator api.
