Referencing objects

These examples illustrate several means to reference an object.

When accessing a specific case of an object, be aware of the occurrence number of the object where the script resides. The script volition return the object with the same occurrence number as the object where the script resides. For example, there are three buttons with the same name (Button1[0], Button1[1] and Button1[2]) and three text fields with the same name (TF1[0], TF1[1] and TF1[two]). If the script on Button1[two] is xfa.host.messageBox(TF1.rawValue), the event will be TF1[2].rawValue , and not TF1[0].rawValue.

Manipulating instances of a subform

These examples illustrate several ways to add or remove instances of a subform at run time.

Use the instance manager to manipulate the pages of a class that has a fixed layout. Each page is a subform; therefore, adding or removing a subform will wait similar adding or removing a page. All the same, at run fourth dimension, you cannot change the layout of a form that has a stock-still layout. Y'all can add and delete instances at the form:ready event; however, if the script is on a run-time event, such equally click, nothing will happen.

Removing an instance

// Remove an case of a subform. Set the min occur value simply if removing an  // instance volition violate it. For example, fix the min occur to 0 if you lot desire to  // remove the last, or the only, instance of a subform.   // Forms rendered in a web browser do non support the underscore syntax.  // Nonetheless, the underscore syntax is supported if the script runs at the  // server.   Subform2.occur.min = "0";  _Subform2.removeInstance(0);

Removing the parent subform

// Remove the parent subform.  parent.occur.min = "0";  parent.instanceManager.removeInstance(parent.index);

Setting the number of instances

// Gear up the number of instances of a subform.  var oSubform = xfa.resolveNode("Subform2");  oSubform.instanceManager.setInstances(5);

Working with folio numbers and page counts

These examples illustrate several ways to use the host and layout models to work with page numbers and page counts.

The host and layout models accept several different backdrop and methods for working with page numbers and page counts. The properties and methods that you should use depend on what the script does and when it executes.

Many of the host backdrop and methods are unavailable on the server. Use the host properties and methods to set or get page numbers at run time.

None of the layout methods gear up the page number. Use the layout methods to get the current page at layout:ready or to display the page numbers at the bottom of the folio and run across the folio number when you lot open up a grade on a client.

Formatting the pagination

// Use the layout page and pageCount methods to format the pagination.  TextField1.rawValue = "Page " + xfa.layout.folio(this) + " of " + xfa.layout.pageCount();

Getting and setting the current page number

// Employ the host currentPage property to get and set the current page number at // run time.  // This script cannot exist used during a layout:ready, form:set up, or initialize // event. Even so, it will work if the script is on a button.  xfa.host.currentPage = ane; // Go to page 2 (0-based).
