Trigger onchange event for a selectbox inside DCT

I have a category and subcateory DCR. I need to populate subcategory based on category selected.

I am able to populate category selectbox using inline-callout and parsing DCR in an .ipl file.

But i couldn't attach a onchange event to that category selectbox.

I want to attach a onchange event to that category selectbox, call a jquery ajax to call a .ipl file to parse DCR file and populate subcategory selectbox.

Can anyone give me a sample ?

Have you looked at the FormAPI guide? What have you tried so far that didn't work?

Pls state your platform version and OS details.

Beyond Rick's response - please define "selectbox":

checkbox (most likely assumption)
single-item select list
multi-item select list (that appears within a "box")
radio buttons (least likely assumption)
Other??

And question number 3, why are you making this so complex ?

There is no need for jquery here, It is simple FormAPI, with a callserver.

Thankyou for the input..

I am new to teamsite, i tried with jquery perviously but now i came to know that there is a seperate FormAPI guide to write scripts in DCT.

Now i am able to populate sub-category based on category.

But when i am placing category and sucategory select box's inside <container> i couldn't populate subcategory response from callserver because of dynamic position.

ex: /categories/maincategory[X-POSITION]/SubCategory

Let me know how i can get the position of category select box while "onItemChange"

The onItemChange event handler function is passed an IWItem object as an argument - implicitly.

Assuming that the replicant instance contains both the "Category" and "SubCategory" items - you should be able to use relative pathing - e.g. (note: this is off the top-of-my-head, untested, and intentionally incomplete):

function init() {
  ...
  IWEventRegistry.addItemHandler("/categories/maincategory/Category", "onItemChange", adjustSubCategory);
  /* Note: the address above is generic, it will work for any instance of 'maincategory' */
  ...
}

function adjustSubCategory(item) {
  /* item points to the explicit '/categories/maincategory[XX]/Category' that was just 'changed' */
  var subItem = IWDatacapture.getItem(item.getName() + "/../SubCategory");
  var subItemOptions = /*...*/;
  subItem.setOptions(subItemOptions);
  return true;
}

Take a look at this sample. It shows some FormAPI techniques to deal with replicant Container changes.

Might be useful...
