如果你想在Magento客户端获取可配置产品里被选中的简单产品，你有很多种不同的方法。

这里有一种简单的方法，不用代码修改，不要新的模版甚至模。值需要一个Java脚本和布局更新。

Product.Config.prototype.getIdOfSelectedProduct = function()
{
     var existingProducts = new Object();
 
     for(var i=this.settings.length-1;i>=0;i--)
     {
         var selected = this.settings[i].options[this.settings[i].selectedIndex];
         if(selected.config)
         {
         	for(var iproducts=0;iproducts<selected.config.products.length;iproducts++)
         	{
         		var usedAsKey = selected.config.products[iproducts]+"";
         		if(existingProducts[usedAsKey]==undefined)
         		{
         			existingProducts[usedAsKey]=1;
         		}
         		else
         		{
         			existingProducts[usedAsKey]=existingProducts[usedAsKey]+1;
         		}
             }
         }
     }
 
     for (var keyValue in existingProducts)
     {
     	for ( var keyValueInner in existingProducts)
         {
         	if(Number(existingProducts[keyValueInner])<Number(existingProducts[keyValue]))
         	{
         		delete existingProducts[keyValueInner];
         	}
         }
     }
 
     var sizeOfExistingProducts=0;
     var currentSimpleProductId = "";
     for ( var keyValue in existingProducts)
     {
     	currentSimpleProductId = keyValue;
     	sizeOfExistingProducts=sizeOfExistingProducts+1
     }
 
     if(sizeOfExistingProducts==1)
     {
    	 alert("Selected product is: "+currentSimpleProductId)
     }
}
