JavaScript to determine if the last page of the document you are working on is left or right

[cafefatbear]

Help me!

I want to know the JavaScript that shows whether the last page of the document I am working on is left or right.

For example..

var a = 8;

if (a === 8) {

 Load the aaa.txt file into the last page on the right.

} else (a ===7) {

 Load the bbb.txt file to the last page on the left.

}

For example..

var a = 8;

if (a === 8) {

 Load the aaa.txt file into the last page on the right.

} else  {

 Load the bbb.txt file to the last page on the left.

}

if (app.activeDocument.pages.lastItem().documentOffset % 2 == 0) { 
    //page is odd (usually right)
} else {
    //page is even (usually left)
}

Use the page's side property:

if (app.documents[0].pages[-1].side === PageSideOptions.LEFT_HAND) {
   // Load bbb.txt
} else {
   // Load aaa.txt
}

This works in left-to-right and in right-to-left documents. The last page's document offset is the same in both types of document.
