valued not getting printed using formAPI

curious_sam

Hello,

I'm facing a problem with the attached DCT.there is a function named validate which is getting called on onSaveValid.There just for testing purpose,i am printing the values from two items.for the val1, it is getting printed(container/item).But for val2(container/container/item),it is giving arrayoutofbound exception.

The DCR type is iwov and TeamSite version is 6.5 SP3.

Can anyone kindly throw some light on what I am doing wrong here.

Thanx in advance

Sam

try something like


var val2=IWDatacapture.getItem("/column1[0]/heading1/text").getValue();
alert("Value 2"+val2);

column1 being a replicant, you must specify which instance of the replicant you're asking for.
in this case /column1[0] ... just make sure you have at least one replicant instance!

Hi,

I tried yr suggestion.But the problem still persists.

any help?

[left]Heading 1 is also a container.
Try this instead.

var val2=IWDatacapture.getItem("/column1[0]/heading1[0]/text").getValue();
alert("Value 2"+val2);

Hi,

I tried that option too, but no result.Same error "ArrayIndexOutOfBound" is showing

Close - the actual answer I believe is:

var val2 = IWDatacapture.getItem("/column1[1]/heading1/text").getValue();

they would start an array at index 1?
Just to be different from everybody else in the programming world?

Is Interwoven the microsoft of content managment systems?

You are too fast to jump into religious wars. Alan **** bashing Microsoft is one thing, he actually delivered some
alternatives to the IT Community. You bashing Microsoft and IWOV - well, forgive my scepticism...

As to your note, the element in question is NOT an Array. It is XPath syntax. You know, part of W3C XSLT standard.
In XPath peer nodes are numbered from 1. If you do not like it, go participate in W3C work, it's open Project.

Didn't mean to offend anyone my apologies. It was more a joke than a debate.

I didn't know xpath peer nodes started at 1, it still seems a bit odd to me as anything else array like in the programming community starts at 0.
Anyway that's a good thing to know.

As to your note, the element in question is NOT an Array. It is XPath syntax. You know, part of W3C XSLT standard.

Actually, the FormAPI guide says that "The notation of FormAPI item addressing is similar to the W3C XPath Recommendation (http://www.w3.org/TR/xpath). The similarity to XPath is limited to the simple notation for node names. Other features of XPath such as wildcard characters, functions, and relative paths are not part of FormAPI item addresses."

So Interwoven modeled their Item Addresses after XPath, but it isn't XPath.

oh, and about Microsoft...

from http://www.w3schools.com/xpath/xpath_syntax.asp
/bookstore/book[0] Selects the first book element that is the child of the bookstore element. Note: IE5 and later has implemented that [0] should be the first node, but according to the W3C standard it should have been [1]!!

cheers ;-)

Thanks Frederik, duly noted Smiley Happy

. Couple comments:

Admittedly partial, FormAPI XPath usage is standard-compliant. It starts with 1 regardless of what browser you use.

Your MS note is somewaht incomplete. For whatever reason Microsoft (IE5+) actually implemented it both ways. Default starts with 0 (!?),
magic setting is xmlDoc.setProperty "SelectionLanguage", "XPath". Use it and all starts with one. As is often the case in our industry
frustrated "but why!?" is a rhetorical question.

I think you can try something like this:

var items = IWDatacapture.getItem("/column1").getChildren();
//Loop through the items
for (var i=0;
i<IWDatacapture.getItem("/column1").getChildren().length;
i++)
{
//Add a check for each of the or containers
if (items.getChildByName('heading1') != null)
{
//Do the processing
alert (items.getChildByName('heading1'));
} else if (items.getChildByName('heading2') != null)
{
//Do the processing
alert (items.getChildByName('heading2'));
}
//Add cases for each of the or containers
}

Thanks,
Josh
