Is it possible to ONLY make one page read-only in a document?

[jlehane]

Hi

I have a button on my test document that makes all fields read only when the salesrep has finished editing.

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

    var fname = this.getNthFieldName(i);

    this.getField(fname).readonly = true; // makes all fields readonly

}

I​t works perfectly, but I've realised that when I add the rest of the pages back into the document, there are fillable fields on pages 2 and 3 that a customer might need to complete once they've received the document.

So, is it possible to make only page 1 read only and leave pages 2 and 3 editable?

Thank you

Sure. You can use this code to do it:

for (var i = 0; i < this.numFields; i++) {
    var fname = this.getNthFieldName(i);
    var f = this.getField(fname);
    if (f.page==0) f.readonly = true; // makes only fields on page 1 readonly
}

I thought that had worked, but it seems to have left all the radio buttons on page 1 editible?

Yeah, fields with more than one "widget" are a bit more tricky... Try this:

if ((typeof f.page=="number" && f.page==0) || (typeof f.page=="object" && f.page.indexOf(0)!=-1)) f.readonly = true;

That's perfect - thank you!

If you don't need the information on the first page to remain in form fields, you can also flatten that page using the Doc.flattenPages() command: Acrobat DC SDK Documentation - Doc.flattenPages()

This will however only work if you have Adobe Acrobat (and not in the free Reader). The JavaScript code to flatten just the first line is this:

this.flattenPages(0);

Thanks for this Karl, I will keep a note of the code a I'm sure it will come into use soon
