remerge(), reset(), resetData()

[jglitch]

Can you reset the elements of a subform? Just a subform! Just like when it was first loaded? If so, how?

Subform contents are Textfields, DropDowns, DateFields, RadioButtons, etc?

Thanks in advance.

The resetData method allows you to pass a string representing a list of fields separated by commas (in the form of a SomExpression). You can try a subform and see if the child nodes get reset as I am not sure if it will only accept a field.

Similar to Paul's suggestion, I built a script to build a string containing all the names of the objects in a subform node of className 'field'. The string of field names is then passed to xfa.host.resetData().

Since the fields have to be comma-delimited, I concatenate the subform name, the field name, and a comma into a string called 'fieldStr'. The value of 'fieldStr' is then concatenated to a variable called 'fieldNames'. When I am done iterating over the subform node I then strip the last comma from the 'fieldName' string.

// form1.page1.subform1.resetBtn::click - (JavaScript, client)

var fieldNames = "";

for (var i=0; i < subform1.nodes.length; i++) {

     if (subform1.nodes.item(i).className == "field") {

          var fieldStr = "subform1." + subform1.nodes.item(i).name + ",";

          fieldNames = fieldNames + fieldStr;

     }

}

fieldNames = fieldNames.substring(0,fieldNames.length - 1);

xfa.host.resetData(fieldNames);

Hi Steve, I was just playing with your script as I have a similar problem in needing to reset fields in a subform, but when I try it it resets all data no matter what subform it's in.

I took your supplied sample and added another subform (not inside the existing subform) and it gets reset as well.

I've tried passing the fields as full strings for resetData("...") in a form I'm working on as well and seem to get the same results.

Any idea what's going on?

No. My script is definitely not much good.

1) I just realized radio button lists do not expose their 'name' attribute in 'field' so the script will never find radio buttons

2) I cannot get resetData() to recognize any programmiatic construction of a string of field names

On the other hand, when you build the resetData() as

xfa.host.resetData("form1.page1.subform1.TextField1,form1.page1.subform1.RadioButtonList");

it behaves a advertised.

The resetData is expecting a string that represents the object name. Are you passing in th entire object or the string of the name. You could use resetData(object.name)

Yeah, actually I've found there's a couple of different ways to pass the fields in...It doesn't need the full path, it just has to know where the field is.

xfa.host.resetData("form1.sMain.SubRegularSurplus.SubPositioned.Vote");

xfa.host.resetData("Vote");

It will reset the data in subforms:

xfa.host.resetData("form1.sMain.SubRegularSurplus.SubPositioned");

xfa.host.resetData(SubPositioned.somExpression);

Some of the weirdness I was getting was that it ws also resetting the visibility of the subform - Think I've got it figured out now. It behaves differently with subforms depending on the expression used.

If I use xfa.host.resetData("SubPositioned"); it resets everything on the form (needs the full path). If I use xfa.host.resetData("form1.sMain.SubRegularSurplus.SubPositioned"); it works ok. And if I use xfa.host.resetData(SubPositioned.somExpression); it works ok.

I found the "somExpression" version in a sample somewhere - not sure how it works...

Quite an old discussion this but thought I'd share my findings.

By re-using the lock fields script provided by pguerret, I've been able to reset data in particulare subforms as follows:

Call to the script object -

clearData.resetAllData(xfa.resolveNode("form1.subform1.subformIWantToReset"));

Then my script object looks like this:

function

resetAllData(myParentObject)

{

     var allChildElements;

     var intNumElements;

     var currentElement;

     var j;

     var temp;

     // get all the child nodes of the parent element

     allChildElements

= myParentObject.nodes;

     // total number of element in the object

     intNumElements

= allChildElements.length;

     // loop through all the child elements

     for(j=0; j<intNumElements; j++)

     {

          currentElement

= allChildElements.item(j);

          // if the element is another subform we'll recusively call the function again

          if(allChildElements.item(j).className == "subform")

          {resetAllData(currentElement);}

          // if the objects are fields

          else if(currentElement.className == "field")

          {

               temp = currentElement.name;

               if ((temp.substring(0,3) != "btn"))

               {xfa.host.resetData(currentElement.somExpression);}

          }

     }

}

My initial testing seems to suggest this has worked.
