Using "/../" for addressing the Parent and Sibling

gururaj

How to address siblings?

if(IWDatacapture.getItem(Caption.getName()+"/../Item_Image").value == "");
{
Caption.setValue=" ";
alert("Add the Image first");
}
There was similar code in FormApi html.

This is in addressing Addressing Parents and Siblings.
They have used "/../" to access the fields.
Please send if there are alternate solutions


Addressing Parents and Siblings
For this custom DTD:

<!ELEMENT b (e, f)>
<!ELEMENT e (#PCDATA)>
<!ELEMENT f (#PCDATA)>

That generates DCRs like this:
<b>
<e>This is e</e>
<f>This is f</f>
</b>

Then the following userscript code returns the item object that corresponds to the element e:

item = IWDatacapture.getItem("/b/e");

To get the parent item that corresponds to the element b, use the `..' notation:

parent = IWDatacapture.getItem(item.getName() + "/..");

To get the sibling item that corresponds to the element f:

siblingItem = IWDatacapture.getItem(item.getName() + "/../f");

Are you saying that this (the "/../" addressing) isn't working for you?

Another way to do it is by string manipulation of the address:

item_addr = new String(item.getName());
re = /\/.*$/;
parent_addr = item_addr.replace(re, "");
sibling_addr = parent_addr + "/sibling_name";
