I have a few forms that are fillable and are utilized in their digital format and as a printable copy to utilize while out in the field. Instead of having an underscore on the base document, is there a way to make the form field box act like the underline? So basically if the form field is blank underline the lower portion of the entire blank box, but if there is text only underline the portion of the box that contains text.
It's easier to implement on the print event, I think, although it's also possible to do it on the screen, but that might cause some delays in the file. If you want to try it out apply the following code as the custom Calculation script of any text field in the file:
for (var i=0; i<this.numFields; i++) {
var fname = this.getNthFieldName(i);
var f = this.getField(fname);
if (f==null) continue;
if (f.type=="text") {
if (f.valueAsString=="") {
f.borderStyle = border.u;
f.lineWidth = 1;
f.strokeColor = color.black;
} else {
f.borderStyle = border.s;
f.lineWidth = 0;
f.strokeColor = color.transparent;
}
}
