Modify javascript to let show previous years
<p>I have this javascript code, i guess this should be where the code has to be changed.</p>

<pre><code> if (this.options.showYear) {
            str += '&lt;select tabindex="'+this.tabIndex+'" class="' + this.options.yearClass + '"&gt;';
            if (this.options.yearOrder == 'desc'){
                for (var y = this.options.yearStart; y &gt; (this.options.yearStart - this.options.yearRange - 1); y--){
                    str += this.addOption(y,y,parseInt(this.calendarYear));
                }
            } else {
                for (var y = this.options.yearStart; y &lt; (this.options.yearStart + this.options.yearRange + 1); y++){
                    str += this.addOption(y,y,parseInt(this.calendarYear));
                }
            }
