JS showing field if dropdown selected

[desirockz]

I am wanting to show a hidden field but only when an option is selected in the dropdown. It does not matter which option is selected but I need one to be selected.Javascript:\[code\] <script type="text/javascript">function Select(sel,id,nu){document.getElementById(id).style.display=sel.selectedIndex==nu?'block':'none';}</script>\[/code\]Selection:\[code\] <select name="options[1]" id="select_1" class=" required-entry product-custom-option" title="" onchange="opConfig.reloadPrice();displayCondition();Select(this,divShow,1)"><option value="" >-- Please Select --</option><option value="http://stackoverflow.com/questions/15713374/1" price="0" >Perfect </option><option value="http://stackoverflow.com/questions/15713374/2" price="-35" >Excellent </option><option value="http://stackoverflow.com/questions/15713374/3" price="-105" >Good </option><option value="http://stackoverflow.com/questions/15713374/4" price="-140" >Poor </option><option value="http://stackoverflow.com/questions/15713374/5" price="-252" >Broken </option></select> \[/code\]The above onchange will only work if the first item is selected, so I am unsure how to make it work for any item selected. Also, I know the divShow should have some ' around it but I don't know how to write it into the following php:\[code\] $extraParams .= ' onchange="opConfig.reloadPrice();displayCondition();Select(this,'."divShow".',1)"';\[/code\]Div Box:\[code\] <div id="divShow" style="display:none;"><?php echo $this->getPriceHtml($_product) ?></div>\[/code\]
