Dynamic Table Index Number

[john_lee7]

I am trying to add/delete row from Adobe form.

There is no direct way to add/delete row dynamically and communicate between adobe form and Web Dynpro, I am trying to figure out differnt way...

Does anyone know how I can figure out index number of current row user clicked add/delete button from adobe form.

I tried several different ways to get index value, but all of them return blank, -1, or 1.

Thanks for any help you can give.

Hi John,

Create a table with the binding "Repeat Table for each data item" with min count as 1. similarly write this binding for the row with min count as 1. Also create only one row. And for header row make min count as 1 and max count as 1, in pagination make check the "Include header row in initial page" and also "include header row in subsequent pages".

Now include create one button in "Header Row" make this as "Add" and one button in "Row" make this as "delete".

Now in the JavaScript editor for

ADD Button: Click event

// nTableLength stores the number of XML elements contained in TableName.

var nTableLength = TableName.nodes.length;

// nNumRow is used to calculate the number of rows contained in TableName.

var nNumRow = 0;

// This script uses a For loop to cycle through all of the XML elements

// contained in TableName.

for (var nCount = 0; nCount < nTableLength; nCount ++) {

// If the current XML element in Table2 is of type subform and it

// is not a header row, then increment the variable nNumRow by one.

// If the table included a footer row, this script would have to

// account for it.

//

// Note: In the Adobe XML Form Object Model, all table rows are

// considered subform objects.

if ((TableName.nodes.item(nCount).className == "subform") & (TableName.nodes.item(nCount).name !== "HeaderRow")) {

nNumRow = nNumRow + 1;

}

}

// An if-else statement is used to prevent form fillers from adding

// more than the maximum number of seven rows to a table.

if (nNumRow == 7) {

xfa.host.messageBox("The maximum allowable number of rows is 7. You cannot add any more rows.", "Warning", 3);

}

else {

// This script uses the addInstance() method to add a new instance

// of the RowName object contained in TableName.

subformname.TableName.RowName.instanceManager.addInstance(1);

}

DELETE button: Click Event

// nNumRow is used to calculate the number of rows contained in TableName.

var nNumRow = 0;

// nTableLength stores the number of XML elements contained in TableName.

var nTableLength = TableName.nodes.length;

// This script uses a For loop to cycle through all of the XML elements

// contained in TableName.

for (var nCount = 0; nCount < nTableLength; nCount ++) {

// If the current XML element in TableName is of type subform, and it

// is not a header row, then increment the variable nNumRow by one.

// If the table included a footer row, this script would have to

// account for that.

//

// Note: In the Adobe XML Form Object Model, all table rows are

// considered subform objects.

if ((TableName.nodes.item(nCount).className == "subform") & (TableName.nodes.item(nCount).name !== "HeaderRow")) {

nNumRow = nNumRow + 1;

}

}

// The Adobe XML Form Object Model uses a zero-based indexing system

// for referencing objects. In this script, the variable nNumRow represents

// the exact number of rows contained in Table1. To convert this to a usable

// index value, the script subtracts one.

nNumRow = nNumRow - 1;

// An if-else statement is used to prevent form fillers from removing

// the single remaining row from a table.

if (nNumRow < 1) {

xfa.host.messageBox("The minimum allowable number of rows is 1. You cannot remove any more rows.", "Warning", 3);

}

else

{

// This script uses the removeInstance() method to remove the last

// instance of the Row1 object (represented by nNumRow) contained

// in TableName.

//subform.TableName.Row1.instanceManager.removeInstance(nNumRow);

_RowName.removeInstance(this.parent.index);

}

NOTE:

1. TableName is Name of your Table

2. RowName is the Name of Row in the Table it is like for eg. Row1

3. subformname is the subform name where the table is present

With the above code you can dynamically add or delete rows
