How to Create your own JavaScript for PDF Forms

JavaScript is crucial to form workflows for companies who want to boast the latest and greatest in document technologies. The article below demonstrates how to add JavaScript to PDF forms with Foxit PDF SDK.

Platform: Windows, Mac, Linux

Programming Language: C++, Java, C#, Objective-C, C

License Key requirement: Standard

SDK Version: Foxit PDF SDK 8.3


Below we will detail six simple demos.

Step 1

AFSimple_Calculate: We will add two text field whose values will be used to add together. The third text field will contain the value of the sum of the first two form fields.

C++:

//AFSimple_Calculate JavaScript for text fields.
void AddInteractiveFormsForSimpleCalculate(PDFPage & page, interform::Form &form) {
//Add the first text field.
Control control = form.AddControl(page, L"Text Field Addend", Field::e_TypeTextField, RectF(50, 600, 90, 640));
control.GetField().SetValue(L"3");
// Update text field's appearance.
control.GetWidget().ResetAppearanceStream();
//Add the second text field.
Control control1 = form.AddControl(page, L"Text Field Augend", Field::e_TypeTextField, RectF(100, 600, 140, 640));
control1.GetField().SetValue(L"23");
// Update text field's appearance.
control1.GetWidget().ResetAppearanceStream();
Control control2 = form.AddControl(page, L"Text Field Sum", Field::e_TypeTextField, RectF(150, 600, 190, 640));//Add the third text field.
//Create a new JavaScript action.
actions::JavaScriptAction javascipt_action = (actions::JavaScriptAction)Action::Create(form.GetDocument(), Action::e_TypeJavaScript);
//Set Javascript
javascipt_action.SetScript(L"AFSimple_Calculate(\"SUM\", new Array (\"Text Field Addend\", \"Text Field Augend\"));");
Field field2 = control2.GetField();
AdditionalAction additional_act(field2);
//Set the JS action to the Additional action of the form field.
additional_act.SetAction(AdditionalAction::e_TriggerFieldRecalculateValue, javascipt_action);
//Trigger this action. Although the set value is 333333, the actual value is 26 by adding 3 to 23.
field2.SetValue(L"333333");
// Update text field's appearance.
control2.GetWidget().ResetAppearanceStream();
}

C#.Net and .Net Core:

static void AddInteractiveFormsForSimpleCalculate(PDFPage page, Form form) {
//Add the first text field.
using (Control control = form.AddControl(page, "Text Field Addend", Field.Type.e_TypeTextField, new RectF(50, 600, 90, 640)))

Add a submit action to a push button: We will now add a push button to trigger the “submit action” to submit data to “http://www.foxit.com“.
