Implementation of a SKU drop down on a Item detail page

[vossgeraldo]

Hi all,

I am trying to implement a drop down functionality for an item detail page for a web site.
However, I am having difficulties getting both the item attribute and
the sku details. I have a form that will populate the sku info and submit them.
At the same time, I want to display the item price , item description and so forth on the same page.
I am using the simpleformController but I'm trying to implement both the handleRequest() method and the onSubmit() method.

Is that doable?

Thanks in advance you for your reply.

If you are trying to show the detail of an item and also look it up on the same page, yes it can be done. If this is not what you meant can you elaborate more on your problem?

Hi Maverick,

Yes, what i'm trying to do is to show the item detail and also have the possibility to pick the item sku from a drop down and show them in my shopping cart on a left nav like most ecommerce sites do.

I will greatly appreciate if you can show me how to do that.

Thanks,

I would do something like this.

In the SimpleFormController subclass

override the referenceData method as follows

Map<String, Object> referenceDataMap = new HashMap<String, Object>();
        referenceDataMap.put("itemSkuList", itemSkuList);
        return referenceDataMap;

bean definition would be something like this for the command assuming sku is a property in Item object

<bean id="someController" class="pathToYourControllerClass">
	<property name="commandClass" value="com.??.Item"/>
	....................
	....................
</bean>

override onSubmit(Object command) method as

ModelAndView modelAndView = super.onSubmit(command);
Item item = (Item) command;
modelAndView.getModel().put("item", retrieveItem(item.getSku()));
return modelAndView;

And your jsp would be something like this

<form:form>
<form:select path="sku">
	<form:options items="${requestScope.itemSkuList}"/> <!-- Matches what you populated into model -->
</form:select>
<input type="submit" ..../>
<form:form/>

<c:if test="${!empty requestScope.item}"> <!-- Matches what you populated into model -->
	// display your item here
</c:if>
