Version 1.3

Bring your forms to life by adding a beautiful progress bar to your contact form, CV, feedback or any other HTML form. Inform your users about the amount of data entered or if you'd like, prevent them to submit the form if the defined percentage has not been reached

A) Description


FORMETER is a jQuery plugin that will allow you to add a fancy progress bar on your registration, contact, settings, CV, feedback or profile form, so the users will be able to see the percentage of form completion.

  • Works in all the major browsers
  • You can change the width and height of each progress bar
  • Generate beautiful progress bars for any form
  • Well documented

B) How to install


Step 1 - Include javascript and CSS files

Extract all files, upload formeter.1.3.js to your server and include it together with jQuery in your webpage head tag or before the closing tag of body.
Also include a link to the formeter CSS stylesheet in your webpage head tag.

<link type="text/css" rel="stylesheet" href="formeter.1.3.css" />
<script type="text/javascript" src=""></script>
<script type="text/javascript" src="formeter.1.3.js"></script>

Step 2 - Create the HTML

Add class required to each input that you want to recommend users to fill it.

<form action="" method="post">
    <input type="text" name="firstname" class="required" />
    <input type="text" name="lastname" />
    <select name="country" class="required">
        <option value="1">Brasil<option>
        <option value="2">Argentina<option>
        <option value="3">Italy<option>
    <input type="submit" name="submit_form" value="Submit">

.meter is the class of the HTML Object that will wrap and set the width of progress bar.

<div class="meter">
    <div id="percentage"></div>

Step 3 - Activate the plugin

Call the plugin on the html element in which you want to show the progress bar.

You can place this piece of code in the header of the site before the tag </head> or, in the bottom of the site before the tag </ body>. Remember that this code should always be placed after jQuery library and formeter.1.3.js was loaded.

<script type="text/javascript">
            speed : 500, // duration of the animation, expressed in milliseconds
            style : 'green', // CSS class assigned to the progress bar
            bubble : false, // Display percentage bubble under the progress bar
            minPercent : 45, // Prevents submitting if the user has not reached this percentage
            message : 'Please fill the required fields !', // The error message displayed to the user
            selector : '.required' // The class assigned to each "input", which we want to count

Our final plugin configuration - Basic setup

The code below will generate a simple HTML5 page, which will demonstrate the simplicity of implementation of the ForMeter plugin.

First, create an empty HTML file called index.html, copy and paste the code below into your HTML file, then copy the file "formeter.1.3.css" and "formeter.1.3.js" next to the HTML file. Open it in your awesome browser :) and ... voila.

Let’s take a quick look at an example:

<!DOCTYPE html>
<html lang="en">
        <meta charset="utf-8" />
        <title>Basic setup example</title>
        <link rel="stylesheet" href="formeter.1.3.css" />
        <!--[if IE]><script src=""></script><![endif]-->
        <script src=""></script>
        <script src="formeter.1.3.js"></script>
                    speed : 500,
                    style : 'red',
                    bubble : true,
                    minPercent : false,
                    message : 'Please fill the required fields !',
                    selector : '.required'

        <div class="meter">
            <div id="percentage"></div>

        <form action="index.html" method="post">
                <label>First name</label>
                <input type="text" name="first" value="John" class="required" />
                <label>Last name</label>
                <input type="text" name="last" />
                <input type="radio" name="gender" value="0" class="required" />
                <input type="radio" name="gender" value="1" class="required" />
                <label>Subscribe to our newsletter</label>
                <input type="checkbox" name="newsletter" value="1" class="required" />
