Acro Javascript: Placement Text in PDF Form Fields

In addition to the post: Acro Javascript: Question Icons / Buttons an additional way to include instruction to users who may have questions when filling out more complex forms is to use placement text within the form fields.

Here’s how the PDF could function:

To do this, start by opening a PDF form. Select the Prepare Form tool to edit the PDF form fields.

Right-click on the form field to put the placement text on and select Properties. Click on the Options tab and enter the Default Value for the form field.

Select the Actions tab, this is where the code gets placed for both On Focus and On Blur.

Here’s the Acro-JavaScript used:
On Focus

if (event.target.value==event.target.defaultValue) {
event.target.value = "";
event.target.textColor = color.black;
}

OnBlur

if (event.target.value=="") {
event.target.value = event.target.defaultValue;
event.target.textColor = color.ltGray;
}
