Checking Blank Fields in Specific Pages of a Multi-Page Document

Question

Hi everyone,Please, I would like your help to figure out how this can be done. Following one of the discussions here, I found the following code to check blank fields, which works amazingly.var emptyFields = [];for (var i = 0; i < this.numFields; i++) {var f = this.getField(this.getNthFieldName(i));if (f.type !== "button" && f.required) {if (f.valueAsString === f.defaultValue) {emptyFields.push(f.name);}}}if (emptyFields.length > 0) {app.alert("Please complete the following fields:
" + emptyFields.join("
"));} else {app.execMenuItem("SaveAs");}However, since my document has 5 pages, I would like to check only the blank fields on the first 2 pages (Not all the document). How can this be specified within this code, please?Thanks alot

I was going to mention the -1 page number for templates but figured it was a long shot you've have this issue. Assumptions always bite 😉

Another assumption I made is that the lexical sort won't matter because you're only interested in single digit pages.

But if you want to be totally correct, I think this code is more compact.

// This code filters the page list for pages (inclusively) between 0 and 1

var aPages = ((typeof(f.page)=="object")?f.page:[f.page]).filter(a=>a>-1 && a<2);

//if the list is not empty, then the field fits the requirement

if (f.type !== "button" && f.required && aPages.length) {

Thank you @Thom Parker much appreacited 🙂
I will go ahead with this being compact and bellow I will leave the full code for who would like to follow:

var emptyFields = [];

for (var i = 0; i < this.numFields; i++) {
var f = this.getField(this.getNthFieldName(i));

var aPages = (typeof(f.page) == "object") ? f.page : [f.page];
aPages = aPages.filter(a => a > -1 && a < 2);

// If the list is not empty, then the field fits the requirement
if (f.type !== "button" && f.required && aPages.length && f.required) {
if (f.valueAsString === f.defaultValue) {
emptyFields.push(f.name);
}
}
}

// Move the alert outside the loop
if (emptyFields.length > 0) {
app.alert("Please complete the following fields:\n" + emptyFields.join("\n"));
} else {
app.execMenuItem("SaveAs");
}

Add code to check the page number of the field. This is more difficult than you would think, because if a field appears on more than one page the field.page property is an array of page numbers.

var nLowestPage = f.page;

if(typeof(f.page)=="object")

nLowestPage = f.page.sort().shift();

if (f.type !== "button" && f.required && (nLowestPage < 2)) {
