Script to tell me if I have more than one frame in the page

Hello,

Please see post below....

https://community.adobe.com/t5/indesign/comment-automatiser-la-recherche-du-nombrede-blocs-par-page-dans-un-grand-nombre-de-pages/td-p/11503172?page=1

var pageFinds = [];
var thePages = app.documents[0].pages.everyItem().getElements();
var tfs;
for (var i = 0; i < thePages.length; i++) {
    tfs = thePages[i].textFrames;
    if (tfs.length > 1) {
        pageFinds.push(thePages[i].name);
    }
}
alert("Pages with more than 1 text frames:\n" + pageFinds.join("\n"));

I made a couple of minor changes to meet your requested needs.

Regards,

Mike
