ResolveNode/Find node?

Say for example the field is called MyTestField, you can use resolveNode() to search for it like so:



xfa.resolveNode("MyTestField");



This is much less efficient than drilling down a bit and looking in a specific section, but if you have no idea where the node could be then you don't have much choice. This will start from the top and search the DOM node by node until it finds MyTestField.

I have a question to go along with this. I'm still not clear on how to get to a certain field in one of the instances of a subform. For example



There are four instances of a subform called mySubForm. In each of the subforms there are three fields: Field1, Field2, Field3. How do I get or set the value for "Field2" in the second instance of the subform?



The occurances of the subform is defined in the Repeat Subform for each Data Item > Initial Count = 4.

So there are a few ways you can do this:



In JavaScript:



form.somToParentSubForm.resolveNode("mySubForm[1]").Field2.rawValue = "test";



or



var nodeList = form.somToParentSubForm.resolveNodes("mySubForm[*]");

nodeList.item(1).Field2.rawValue = "test";



In FormCalc you could go direct:



form.somToParentSubForm.mySubForm[1].Field2.rawValue = "test";



Basically, '[' and ']' can't be used in a JavaScript expression so you use resolveNode in JavaScript to access the specific instance of the subform you want.

I got the first two JavaScript examples to work. Thanks.



I held down the control key then clicked on the field I wanted to access to get the following path.



xfa.resolveNode("form1.mainPage.mySubForm.Field2")



Then I made some changes to some of this line as in,



xfa.resolveNode("form1.mainPage.mySubForm[1].Field2");



I couldn't understand why it wasn't working when I put in the instance number (mySubForm[1]). It seemed logical to me. It looks like I have to isolate the instance inside the parenthesis first then access the field outside the parenthesis.

Chris,



Despite it seems simple, I can´t see xfa.resolveNode("MyTestField"); working... I always get a null object/value. I´m using Acrobat Professional 7.0.5. Can it be a version problem?



Thank you

Shouldn't be a version problem. It seems to work here for me. Can you put your form online somewhere that I can take a quick look at it?

Hi,



Sorry, I just work inside an Intranet...

The form where I tested is very simple: two subforms with a text field in the second one. Then I use this code at doc ready event of the main form:



var c = xfa.resolveNode("TextField1");

app.alert(c); //Gets null ....



Thank you!

Ok, try this form then. Does it work for you? It does for me. What's different between my form and yours?

Hi,



It works... However, if I had a subform from my Designer... it will not work again. I´m using designer 7.0. However, I tried in Designer 7,1 and the problem persist...



When I place a new subform at the form the subform gets call SubForm1 and not (untitled Subform). Can be this a clue for the error?



Thank you

Ok,



I got it. If you rename the subForm where the text field is, you get the null value. How come?
