jQuery plugin dynamic character count for textareas and input fields

Overview

jQuery plugin Simplest Twitterlike dynamic character count for textareas and input fields.

About charCount

The first thing that this plugin do is create a sibling element (it adds is immediately AFTER the form element), the "counter", where the remaining character info is stored. On each key up event or text field value change the counting function is triggered and the contents of this "counter" element is changed accordingly. If the remaining character count reaches the "warning" zone (gets close to zero) the CSS class is added. We use this class to change the color of the character count info. If the count reaches zero and goes beyond it another class is added so we can use another style for exceeding the limit.

Just so you can find your way around it, this is the code that the plugin generates by default:

<span class="counter">140</span>

Plugin Options (and default values)

$("#message1").charCount();

$("#message2").charCount({
    allowed: 50,
    warning: 20,
    counterText: 'Characters left: '
});

form .counter{
    position:absolute;
    right:0;
    top:0;
    font-size:20px;
    font-weight:bold;
    color:#ccc;
}
form .warning{color:#600;}
form .exceeded{color:#e00;}

Installation

• When you're reading this you have probably already run easy_install collective.js.charcount. Find out how to install setuptools (and EasyInstall) here: http://peak.telecommunity.com/DevCenter/EasyInstall

• Get pythonproducts and install it via:

  python setup.py install --home /path/to/instance
  

  into your Zope instance.

• Create a file called collective.js.charcount-configure.zcml in the /path/to/instance/etc/package-includes directory. The file should only contain this:

  <include package="collective.js.charcount" />
  

Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

• Add collective.js.charcount to the list of eggs to install, e.g.:

  [buildout] ... eggs =

  System Message: ERROR/3 (<string>, line 151)

  Unexpected indentation.

  ... collective.js.charcount

• Tell the plone.recipe.zope2instance recipe to install a ZCML slug:

  [instance] recipe = plone.recipe.zope2instance ... zcml =

  System Message: ERROR/3 (<string>, line 160)

  Unexpected indentation.

  collective.js.charcount

• Re-run buildout, e.g. with:

  $ ./bin/buildout

You can skip the ZCML slug if you are going to explicitly include the package from another package's configure.zcml file.

After updating the configuration you need to run ''bin/buildout'', which will take care of updating your system.

Go to the 'Site Setup' page in a Plone site and click on the 'Add-ons' link.

Check the box next to collective.js.charcount and click the 'Activate' button.
