Formcalc examples adobe

FormCalc formats the result to the specified width and rounds to the specified number of decimal places. Returns the number of periods required to reach a given future value from periodic constant payments into an interest-bearing account. Returns the units of a unitspan. A unitspan is a string consisting of a number followed by a unit name.

Returns the numeric value of a measurement with its associated unitspan after an optional unit conversion. Scripting with FormCalc and JavaScript. FormCalc function Description JavaScript method equivalent Abs n1 Returns the absolute value of a numeric value or expression.

None At s1, s2 Locates the starting character position of a string within another string. None Ceil n1 Returns the whole number greater than or equal to a given number. None Concat s1 [, s None CTerm n1, n2, n3 Returns the number of periods needed for an investment earning a fixed, but compounded, interest rate to grow to a future value. None Date Returns the current system date as the number of days since the epoch. Date2Num d1 [, f1 [, k1 ] ] Returns the number of days since the epoch, given a date string.

The JavaScript Date object does not use the epoch as a reference point. DateFmt [ n1 [, k1 ] ] Returns a date format string, given a date format style. None Decode s1 [, s2 ] Returns the decoded version of a given string.

Encode s1 [, s2 ] Returns the encoded version of a given string. Eval Returns the value of a given form calculation. None Floor n1 Returns the largest whole number that is less than or equal to the given value. None FV n1, n2, n3 Returns the future value of consistent payment amounts made at regular intervals at a constant interest rate. None HasValue v1 Determines whether the given parameter is a valid reference syntax with a non-null, non-empty, or non-blank value.

None IPmt n1, n2, n3, n4, n5 Returns the amount of interest paid on a loan over a set time. None IsoDate2Num d1 Returns the number of days since the epoch, given a valid date string. None IsoTime2Num d1 Returns the number of milliseconds since the epoch, given a valid time string. None Left s1, n1 Extracts a specified number of characters from a string, starting with the first character on the left. None LocalTimeFmt [ n1 [, k1 ] ] Returns a localized time format string, given a time format style.

None Lower s1 [, k1 ] Converts all uppercase characters within a specified string to lowercase characters. None You can use JavaScript regular expressions to perform this operation. Max n1 [, n NPV n1, n2 [, None Num2Date n1[, f1 [, k1 ] ] Returns a date string given a number of days since the epoch. None Num2Time n1 [,f1 [, k1 ] ] Returns a time string given a number of milliseconds from the epoch. None Oneof s1, s2 [, s None This function is similar to the String. Parse s1, s2 Analyzes the given data according to the given picture format.

None Pmt n1, n2, n3 Returns the payment for a loan based on constant payments and a constant interest rate. None PPmt n1, n2, n3, n4, n5 Returns the amount of principal paid on a loan over a period of time. For example, the following expression selects all objects named item on a form:. You can use two dots at any point in your reference syntax to search for objects that are a part of any subcontainer of the current container object, such as a subform.

As a second example,. The number sign notation is used to denote one of the following items in a reference syntax:. The following reference syntax accesses the name property of a subform if the subform also contains a field named name :. The square bracket [ ] notation denotes the occurrence value of an object. In language-specific forms for Arabic, Hebrew, Thai, and Vietnamese, the reference syntax is always on the right even for right-to-left languages.

To construct an occurrence value reference, place square brackets [ ] after an object name, and enclose within the brackets one of the following values:. An occurrence number that is out of range does not return a value. For example,. Positive values yield higher occurrence numbers, and negative values yield lower occurrence numbers. This reference yields the occurrence of Quantity whose occurrence number is two more than the occurrence number of the container making the reference.

For example, if this reference was attached to the Quantity[2]object , the reference would be the same as. The most common use of this syntax is for locating the previous or next occurrence of a particular object. For example, every occurrence of the Quantity object except the first might use Quantity[-1] to get the value of the previous Quantity object.

Click on Layout. Select the Script Editor. Select an Object in the Layout. The Script editor will be displayed as shown below.

Objects are used to display the data in PDF Forms. Based on the data type we have to select Object from object library and add it to layout. We can divide the objects into two categories. FormCalc is the default scripting language in Designer. It is an easy-to-use calculation language.

FormCalc is the best choice to work on functions like date and time, financial, arithmetic , logical etc. FormCalc usually provides better performance than JavaScript because it executes calculations and validations more quickly. FormCalc can be the best choice in many situations, regardless of programming experience. This scripting language is very useful for Non Programmers who need to add calculations for their forms.

Go to SFP. Enter the Name of the Form and click on Create. A pop will be displayed as shown below. Assign Interface for your form. Interface is the place where we add code to fetch data from Data base tables. We can display the database. Context is the place where the connection is established between Interface and Form.

Example 1 :. Select the Field. Go to Script Editor. In Script editor select the event form ready. We can see the Header line which represents the path of the form. NumericFieldready:form — FormCalc, client. Although FormCalc is default scripting language in designer, Java script is more ideal for creating sophisticated interactive and dynamic forms. JavaScript is a scripting standard that many programmers and designers already know. We can create JavaScript objects and custom functions, and use them through out Form.

However, it is the script that calls the subform's instance manager with the directive to create a new instance. This script runs on the button's click event. Figure 4. Another practical script is found in the Grand Total text field numGrandTotal. This script automatically calculates the grand total for the purchase order every time a financial event on the purchase order occurs.

When a new item is entered or when a new tax is applied, the grand total is automatically recalculated. This is a very useful script for form fillers because they can see how all of their changes and additions to the purchase order affect the bottom line.

Unlike the previous script, which ran on the click event, this script runs on the text field's calculate event. You'll learn how these different events affect your form's performance in the "Events" section later in this chapter. Although you don't absolutely need scripting in your forms, a small investment in scripting will yield all of the following benefits to you and your form fillers:.

You can create calculations and scripts that impact all form design objects. However, you can only add calculations and scripts to the form events of a particular object. The following table provides a quick reference of scripting support for objects available in the Standard category of the Library palette.
