Calculating the field sums

This example demonstrates how to calculate the sums of fields located at different levels of the form hierarchy when the form filler opens the form in a client application, such as Acrobat Professional, Adobe Reader, or HTML client.

Scripting for calculating the sum of repeating fields in a form

To calculate the sum of repeating fields in a form, you add a calculate event to the Sum field:

var fields = xfa.resolveNodes(“NumericField1[*]“);

 

var total = 0;

for (var i=0; i <= fields.length-1; i++) {

total = total + fields.item(i).rawValue;

}

 

this.rawValue = total;

Scripting for calculating the sum of repeating fields

Similarly, to calculate the sum of repeating fields, you add a calculate event to the Sum field:

var fields = xfa.resolveNodes(“detail[*].NumericField1″);

 

var total = 0;

for (var i=0; i <= fields.length-1; i++) {

total = total + fields.item(i).rawValue;

}

 

this.rawValue = total;

Scripting to calculate the sum of the fields on the page

To calculate the sum of the fields on the page, you add a calculate event to the Sum field:

var fields = xfa.layout.pageContent(0 , “field”, 0);

 

var total = 0;

for (var i=0; i <= fields.length-1; i++) {

if (fields.item(i).name ==”NumericField1″) {

total = total + fields.item(i).rawValue;

}

}

 

this.rawValue = total;
