Four color spaces are supported: transparent, gray, RGB, and CMYK. The first member of the array is a string that indicates the color space. In AcroForm JavaScript, colors are represented with an array of values. OFld.fillColor = oFld.borderColor = oFld.textColor = First acquire the field to be disabled Function to disable form fields function Var oNmlFld = this.getField("NormalColorsFld") Next acquire the hidden field with the normal colors

Create a new Document Script (the name of the script is unimportant) and enter this code: // Function to enable form fields function In an AcroForm, the Enable and Disable functions are placed in a Document Script. The example file, “ DisableFields_AcroForm.pdf”, shows these more complex methods. Or you may want to use the fancier method of lightening and darkening existing colors. In this case, you will need one hidden field for each color scheme. Of course, your form may have several different color schemes for different kinds of form fields. To keep things simple, we’ll use shades of gray to disable a field and assume all fields on the form have the same coloring scheme, i.e., we have a single hidden field that acts as our color standard. In order to handle enabling and disabling any form field on the document, we’ll need two generalized functions, one for enabling fields and one for disabling fields. Using fields is simpler to set up and maintain than hard coding values, since the color palette is used for color selection and you can immediately see how the field will look. However, the easiest method is to place hidden fields on the form that use the normal colors.

One method to accomplish this is to hard code the field colors into a document script. To handle all of these situations, the original field colors need to be permanently stored somewhere in the document. The document may be opened and saved many times, as well as passed around to different computers and platforms. This restoration could happen at any time. Whichever graying method is used, at some point the original field colors will have to be restored. It has to be grayed- out for the user to know the field is disabled. But, it still looks identical to a usable field. The user can’t enter data into a read-only field and the field is taken out of the tabbing order. The first requirement is handled by making the form field ready-only, a feature available in both forms technologies. The gray color should not obscure the form-field contents, but make them less obvious than enabled fields.

The basic ideaĪ disabled form field has two main properties: This article will present specific code for each forms technology. While the implementation details differ between both LiveCycle and Acrobat forms, the methodology for graying-out fields is exactly the same in both. But again, disabling the employee section makes it obvious which sections are to be filled out, and which ones aren’t. It may be helpful, or even necessary, for a manager to see entries filled by an employee. Another example is a form with sections intended for more than one person, such as manager and employee sections. If the spousal information is not necessary, then the flow of filling out the form can be vastly improved by graying it out, thus making it obvious to users they can skip this section. For example, a form may have entry areas for both applicant and spouse. Each of these is useful in its own way, but neither is satisfactory for the situation where the user needs to see options only available under certain circumstances. About the closest you can get with built-in features is either hiding a field or setting it to read-only.

Prerequisites: LiveCycle Forms and JavaScript familiarityĭisabling, or graying-out, form fields is a common feature in software applications, but is somehow missing from Acrobat and LiveCycle forms.
