Replicant question

Hi,

I am wondering if someone can give me a little guidance. I am very new to formAPI and TeamSite. I have a small request to update a DCT. My requirement is as follows.

"If the user enters text into the Image Text area, the ALT Tag text area should be a required field".

The problem I am facing is these text area's are within a "replicant". The code is as follows:

"
"
.
.
.
.
.
.

The maximum number of characters for the folder path of the image is 250. The maximum image size is 150 x 150 pixels.

The maximum number of characters for the alt tag is 500.

.
.
.

I know to set the field to be required I use the following:

IWDatacapture.getItem("Section[??]/ALT Tag").setRequired(true);

But what I am confused about is how to "loop" through the replicant items where the [??] is the value of the replicant.

Can someone please shed some light.

Greatly appreciated!

For some reason the code did not attach:

replicant default="1" min="1" max="18

item name="Image
description> The maximum number of characters for the folder path of the image is 250. The maximum image size is 150 x 150 pixels.
item name="ALT Tag
description> The maximum number of characters for the alt tag is 500.

You can loop through with GetChildren.

However for this application you should not need to.

you will have a onChange event trigger (Section.Image) something like:



IWEventRegistry.addItemHandler("/Root/Section/Image", "onItemChange", makeRO);

function makeRO(item)
{  var path = item.getName();
 var altpath = path + "/../Alt"

go from there.

Welcome to the forums - the forum software will interpret html / xml tags unless you wrap them in [html]...[/html] tags (or [code]...[/code] tags - but you still have to do some finessing work)
Also - learn to use the Preview Post option ...

Please find and read the FormAPI Developer's Guide and look at the documentation for getChildren - that will show you how to loop - though in this case - I think an event handler function for onItemChange of the Image item might be a better choice - the handler function will be passed the item that changed, and you can use javascript to create an "ALT Tag" item using the name of the current item and replacing "Image" with "ALT Tag" -- NOTE: you'll be better off if you name the items without spaces (e.g.: "alt_tag") and use the

to get a friendly name for the item in the DCT form.
