How to get value from the plugin?
<p>I'm trying to create a simple plug-in. </p>

<pre><code>jQuery.fn.mask = function(options) 
    {
        var mask = '#mask';

        var options = jQuery.extend
            ({
                maskWidth : 800,
                maskHeight : 600,
                maskBgcolor : 'silver',
            }, options);


        return this.each(function()
        {            
            jQuery(this).append('&lt;div id="mask"&gt;&lt;/div&gt;');

            jQuery(mask)                                                                    
                        .css('width', options.maskWidth)
                        .css('height', options.maskHeight)                                                                                 
                        .css('background-color', options.maskBgcolor) 
        });
    };
</code></pre>

<p>Calling plug-in </p>

<pre><code>$('body').mask(); 
</code></pre>

<p>How can I get, for example, the width of "#mask". </p>

<p>Something like this </p>

<pre><code>var w = $(this).mask('width') / / in the variable - 800
</code></pre>

<p>Or other way...</p>

<p>What code should write a plugin?</p>
