I have a question about Adobe Acrobat Pro DC if anyone can help.
I don't think it's too advanced, but I'm a bit out of the loop. I have a form that I want people to be able to fill out, and I want there to be default text displayed that they can click the field and input their own.
Using simple Java for the "click and it disappears" part
if (event.target.value == event.target.defaultValue){
event.target.value = "";
}
And the inverse for clicking off of it if the field is blank.
My problem is that I want the default text there so that people can know what they should input, but not all fields are required to be filled in if not needed. Is there a way to check for a print event or something or to make a field switch from "Visible" to "visible but doesn't print" if the default text is left in the field?

Ok guys no need to argue,here is updated script: for ( var i = 0; i < this.numFields; i++) { var fname = this.getNthFieldName(i); if (this.getField(fname).type == "text" && this.getField(fname).value == this.getField(fname).defaultValue) this.getField(fname).display = display.noPrint; else this.getField(fname).display = display.visible;}

Yes you can use "Will print" event.

While in 'Prepare form' tool, click on 'More'->'Document Actions'-> and select 'Document Will Print', now click on 'Edit' and paste script inside (replace "Default text goes here" with your text):

for ( var i = 0; i < this.numFields; i++) {
var fname = this.getNthFieldName(i);
if ( this.getField(fname).value == "Default text goes here")
this.getField(fname).display = display.noPrint;

else this.getField(fname).display = display.visible;}

- Since not all fields have the same default value necessarily it's better to use the defaultValue property then a hard-coded string.

- You need to add a condition to turn the field's display back to visible, or it will never print once you try to do it with an empty field, even if you fill it in later on.

I added line to make it back to visible but I'm not so sure about defaultValue.

Wouldn't set it to defaultValue also make other text fields that doesn't have set default value and buttons...etc to noPrint?

Well, you have to skip buttons entirely, as they don't have a value property and trying to access it will result in an error.

No. As I said, you have to skip them in the loop, so their display property is not changed.

Sorry, but this code is not quite good. It will skip all non-text fields (including drop-downs, check-boxes, etc.), and will make all buttons visible, even if the author of the form originally set them up as not printable.

I would use this code, instead:

 

for ( var i = 0; i < this.numFields; i++) {
	var fname = this.getNthFieldName(i);
	var f = this.getField(fname);
	if (f.type=="button") continue;
	if (f.valueAsString == f.defaultValue)
		f.display = display.noPrint;
	else f.display = display.visible;
}

They never wrote that. They wrote about the "default text" in the field. That can be a drop-down, too. For example, it can have the default value as "SELECT" and you don't necessarily want to print that.

Anyway, it's not nit-picking because that code will also have other unintended results, such as editing the visibility of all non-text fields.

My point is you will always find a way to improve script but that just nitpicking.

I can also say your code is wrong too, OP can also have list box fields and your code will change it to not printable.

Correct, if the default value is selected in it, it won't print. I don't think that's necessarily against their wishes, but we'll let them decide.

Awesome, thanks Nesa!  That works like a charm!

And to the debate, it's a scanned form for a bid sheet for my union, but with fillable text fields so people can save copies from the website I'm putting together to send out.  I'm constantly reworking it (want to get rid of those darn highlights so bad lol but I know that's a lost cause) and making it more user-friendly as kind of my prototype for how I'll do all the other forms, but I think it's nearly done.  I used a slightly modified version of Mz. Nurani's script (which worked fine out of the box) and it works beautifully.  I'd like to thank everyone here, and that business about buttons and drop-down boxes is an interesting point, and something I may have to consider for other forms.
