Script for skipping to next page (of imported pdf/ai/ind)?

Hi Jan,

years ago John Hawkinson did a script that would invoke the place options on an already placed PDF, InDesign page or AI file, I think. Hope, I can find the old thread or the ExtendScript code. You could build on this. But be warned: Not all PDFs would show how many pages are inside. At least you cannot see this by scripting.

Ah. Found the extended script I did, based on John's original one:

// PlaceAgain-PlaceOptionsShowing-SELECTION.jsx
// Uwe Laubender

//DESCRIPTION:Select a placed image, PDF or InDesign document to replace it with itself getting options

/**
* @@@BUILDINFO@@@ PlaceAgain-PlaceOptionsShowing-SELECTION.jsx !Version! Fri Sep 09 2016 14:09:53 GMT+0200
*/

	You can either select the placed file directly or its container frame.
	Or, if its part of a group, the group itself.
	Or, if the container frame is pasted inside another object, that object.

placeAgainSelection();

function placeAgainSelection()
{
	if(app.documents.length == 0){alert("ERROR"+"\r"+"No document is open."); return};
	if(app.selection.length != 1){alert("ERROR"+"\r"+"Select one single item containing a placed file."); return};

	// The placed object is selected:
	if
	(
		app.selection[0].constructor.name == "ImportedPage" || 
		app.selection[0].constructor.name == "PDF" ||
		app.selection[0].constructor.name == "EPS" ||
		app.selection[0].constructor.name == "Image" ||
		app.selection[0].constructor.name == "PICT" ||
		app.selection[0].constructor.name == "WMF"
	)
	{	
		var graphic = app.selection[0];
	};
	
	else if(app.selection[0].allGraphics.length == 0){return};
	
	// The container of the placed object is selected:
	else{var graphic = app.selection[0].allGraphics[0]};

	// Two important checks:
	// Case 1: Graphic was pasted on the page from e.g. PhotoShop:
	if(graphic.itemLink == null){alert("ERROR"+"\r"+"The graphic was pasted on the page. The original file cannot be found.");return};
	// Case 2: Link is not available, because placed graphic was renamed, removed or otherwise is not available:
	var file = File(graphic.itemLink.filePath);
	if(!file.exists){alert("ERROR"+"\r"+"\""+file.name+"\""+"\r"+"File cannot be found."); return};
	
	// If you cancel the place options dialog, no error will be thrown:
	try{
	graphic.place(file,true);
	}catch(e){};
};

Important Note:

The original thread from 2016 where I posted the script code did not make it to the new InDesign forum.

Because of that this thread where I mentioned my script is rendered useless:

This one as well, but there is also a link to a script by Roland Dreger that could be useful:
