Accessing form array objects through javascript

[Marty_Lampard]

I have what I hope is an easy question that I've been beating my head on for days....

Say I have a form with multiple fields of the same name - let's call the fields recordedHours.

Adobe assigns an index to each instance of the field, so we'll have recordedHours[0], recordedHours[1]... recordedHours[30]

Now I need to set and get the values using Javascript, so something like:

for (i=0; i<=30; i++)

{

  var hrs = this.recordedHours[i].rawValue;

}

This doesn't work. Neither does a full reference: form1.timeform.recordedHours[i].rawValue

or getElement: this.getElement("recordedHours",i)

or dot notation: form1.timeform["recordedHours"].i.rawValue (syntax error, as i, when converted to numeric gives an illegal object/element identifier)

I have tried every way I can possibly think of to get and set the values through Javascript and I've searched high and low on the web but can't find anything - I know I'm probably suffering from SUS (Stupid User Syndrome), but can anyone help me out here?

Cheers,

Marty.

The issue is that you have to resolve the expression to be able to get the right index so you can use the xfa.resolveNode syntax. This allows you to pass in a string and that gets interpretted for you . So the syntax woudl be:

for (i=0;i<=30;i++){

     var hrs = xfa.resolveNode("form1.Page1.recordedHours[" + i + "]").rawValue

}

Hope that helps
