Introducing jQuery Gavel

A simple jQuery validation plugin.

I’ve always found it annoying how most javascript/jQuery validation plugins are either extremely hard to customize or extraordinarily bloated. Every time I needed to do something a little more complex than the norm I was faced with having to add clunky additions, switch to another plugin or in the worst cases switch to fully custom validation. As a result I decided to make an attempt at something a little more practical.

jQuery Gavel

Gavel was born from annoyance. I can’t say it is better than alternatives but it definitely was a worthwhile learning experience. It gets its job done with minimal hassle and when anything more complex is needed it has a simple set of easily extendable functions.

So, if at any point you in need a simple, very lightweight plugin give Gavel a try. It is quite easy:

<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="jquery.gavel.js"></script>
<form method="GET" name="example" id="example">
    <input name="example_input1" type="text" data-gavel="required|alphabetic"/>
    <input value="Submit" id="submit" type="submit"/>

Basically, you just need to indicate what fields are handled by Gavel by adding the ‘data-gavel’ attribute:

<input name="example_input1" type="text" data-gavel/>

Then you can add all the validation rules you require:

<input name="example_input1" type="text" data-gavel="required|alphabetic"/>

Finally, initiate the plugin on the form:


The following is a list of rules available to Gavel by default:
