I had create a sample data test at.

https://drive.google.com/file/d/1sTILHTJAtqSZwc4PmCifKmf0GznoZuxp/view?usp=sharing

 

This is my script ( run script from console window of Acrobat): 

 

var link_info = "";
var ckWord ;	
var iPageGoto;
for (var p = 0; p < 200; p++)
{
    var numWords = this.getPageNumWords(p);

	var st=new Date();
	console.println(p + st);

		for (var i=0; i<numWords; i++)
		{       
			 ckWord = this.getPageNthWord(p, i, false); 
			if (ckWord.search("P\\.")>=0)
						{
				iPageGoto =this.getPageNthWord(p, i+1, true);
				
				if(iPageGoto>0)
				{
				   link_info +=iPageGoto;
				}
				iPageGoto=null;
			}
			ckWord=null;			
				
		}	

}
event.value = link_info;

 

 

This is result of Acrobat Pro 2023 64 bit: Time is 1h 11' 

It hang at Page 137

 

var link_info = "";
var ckWord ;	
var iPageGoto;
for (var p = 0; p < 200; p++)
{

    var numWords = this.getPageNumWords(p);

	var st=new Date();
	console.println(p + st);
	


		for (var i=0; i<numWords; i++)
		{       
			 ckWord = this.getPageNthWord(p, i, false); 
			if (ckWord.search("P\\.")>=0)
						{
				iPageGoto =this.getPageNthWord(p, i+1, true);
				
				if(iPageGoto>0)
				{
				   link_info +=iPageGoto;
				}
				iPageGoto=null;
			}
			ckWord=null;
			
				
		}
	

}

event.value = link_info;

I modified your code to print link_info to the console, and only print out the start and end times, and ran it on the file you shared in Acrobat XI. Runtime was ~15 seconds.

Yes, Acrobat XI is Ver 32bit. 

 it only occur with Ver 64bit (Pro DC 2022 64bit, Pro DC 2023 64bit)

@Amal. 

@S. S 

Is there any solution for this problem?

Is this script being run from inside a field? or from the console window?

 

There are a couple of issues with the code, but nothing that would cause the problemw you've described. Text extraction has gotten slower and more buggy with each new version.  In Acrobat 9 it was blazing fast and has gone down hill quickly since then. 

 

Why is the number of pages hard coded?  

Use this instead:

for (var p = 0; p < this.numPages; p++)

 

This line is a possible problem because the next word might not exist:

			iPageGoto =this.getPageNthWord(p, i+1, true);

 

Use this instead

   			if(++1 < numWords)
   			   iPageGoto =this.getPageNthWord(p, i, true);
   			else
   			   continue;

 

However, the most likely issue causing Acrobat to crash is that the JS engine is running out of resources. Text extraction is memory intensive. You might try freeing up memory by deleting the word variables. I doubt this will help much. 

 

delete ckWord;

delete iPageGoto;

I run script  from the console window.

I'm testing , so setting 200 pages to limit time.

I had try add, but it still not ok.

delete ckWord;

delete iPageGoto;

 

And I confirmed, it only happens with Version 64bit .

Ver: Pro X,  Pro DC 2015, Pro DC 2023 32 bit => It is ok.

Ver: Pro DC 2022 64bit, Pro DC 2023 64bit => It hang very long.

I think this is a problem with Acrobat that you might not be able to get past.

I would try limiting the run to 100 pages at a time. See if just doing it in batches works.
