Script that list form feilds

Hello all, I would like to list all the fillable fields in a PDF in an array for each page. I found a page that seems to say its script will do just that. I cannot get it to work. Could someone take a look and tell me what is wrong. In the function that is created should I be inserting my document name? If anyone has a better way to do this I will appreciate that as well.

 

The page that offers a script: Page at Acrobat Library 

 

function getPageFields(doc, p) {
var fields = [];
for (var i=0; i<doc.numFields; i++) {
var f = doc.getField(doc.getNthFieldName(i));
if ((typeof f.page=="number" && f.page==p) || (typeof f.page!="number" && f.page.indexOf(p)>-1)) fields.push(f.name);
}
return fields;
}

 If my results are listed in the console it is fine. I want the listing to refer to them elsewhere. Thanks for any help.

How many form fields are you expecting to see listed?


I see now... I did not know I had to adjust the function for the page number. I thought it would loop through every page. I get it, and this is very helpful.  I am new to Acrobat scripting so I want to learn more because I see how powerful it is. Thank you so much.

I definitely need to learn more about how this all works. I see simple programming constructs that I know something about are different here. For example, if I stack up the functions that return the fields but manually, they return what I want.

console.println("Page 2: " + getPageFields(this, 1)  + "Page 5: " + getPageFields(this, 6)  + "Page 11: " + getPageFields(this, 12)  + "Page 20: " + getPageFields(this, 19) );
// This returns the fields from page 2, 5, 11, and 21

However, if I do this with a loop it seems to need different syntax than I am used to.

var intTotalPages = this.numPages ;
for ( var i = 1; i < intTotalPages; i++ ) {
console.println( "Page " + (i + 1) + ":" + getPageFields(this, i));
}
This returns undefined every time.

Could someone explain what is different here about using a loop? Thanks

The syntax is the same. "undefined" doesn't mean there was an error, just the opposite. It means that the code completed running without errors and without returning any values. The issue is you're not seeing any output in the console, but in order to debug that we'll need to see the actual file with the full code.

Here you go... this is an example of a document that is so lengthy it is good to have a list of fields so you do not miss anything. I would like to loop through and print all of them to the console. Optimally I would like to have them listed (organized) by page that they reside on. I have already inserted the JavaScript the way it was taught to me in the messages above. Thanks for any help/ideas.

This is a document level script.

 

The first part of the script is declaring a function, which is  what you currently posted from that link.

 

The second part of the script has to call this function. You need to call the function using this other script:

 

getPageFields(this, 0);

 

In my example slides below I  used the JavaScript tool --->> Document Scripts to create the function. 

 

 

 

 

Then I added a button with a Mouse-up event to call the function and report back to the console with this line:

 

console.println(getPageFields(this, 0));

 

The results look like shown below when I call the function from the button and open the console:

Hi, thanks for the reply. I think I did the first part correctly. However, as for creating a button I used the tools on the right and searched for button. I then set the button up, I choose All Properties and then Run a JavaScript -> Add I put the

console.println(getPageFields(this, 0));

there. When I press it with the console open I just get the default button name in the console. In my case "Button1". I think I am not setting up the button correctly.
