As part of the form design process, a form developer can use calculations and scripts to provide a richer user experience. You can add calculations and scripts to most form fields and objects. For example, the following JavaScript script multiplies the values of two numeric fields together and displays the result in a third numeric field:At a more advanced level, you can create your own functions tailored towards your own custom form processing needs.LiveCycle Designer ES supports two scripting languages, each geared towards the needs of a particular type of form developer. FormCalc is a straightforward, easy-to-use calculation language that is modelled on common spreadsheet functionality. It includes a variety of built-in functions designed to reduce the amount of time you need to spend developing your form design. JavaScript, a powerful scripting language, provides you with a great deal of flexibility when creating your scripts and allows you to leverage any existing knowledge of the language.Remember that scripting on a form is entirely optional. You can choose to take advantage of scripting to provide a richer user experience, but many of the most powerful features available during form creation are available in LiveCycle Designer ES without the use of scripts. However, through scripting, you can manipulate and control almost all aspects of your form design.
