Copied

In pdf ,

 

I want to Create hyperlink on all numbers with dot (.) (1. , 2. , etc..)

 

This number will be in the starting of paragraph which has destination with same number with #

 

Note destination number with # can be on different page 

 

+++++++

 

Below is the code..

 

// Iterate through all pages of the PDF

 

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

 

  var page = this.getPageNum(pageNum);

 

  var pageText = page.extractText();

 

  // Use a regular expression to find numbers with dots at the beginning of paragraphs

 

  var numberRegex = /^\d+\./gm;

 

  var match;

 

  while ((match = numberRegex.exec(pageText)) !== null) {

 

    // Extract the matched number with dot

 

    var numberWithDot = match[0];

 

   /////////// Hyperlink and hyperlink destination code will come here .....

 

  }

 

}

 

 

++++++

Error

 

this.getPageNum(pageNum) is not a function

 

tried alternative, 

 

this.getNthPage(pageNum)

 

this.getNthPage(pageNum) is not a function

 

How do I exactly get the content of the page and match it with regex. Please help.

 

In the indesign script there is a doc.findGrep() function which makes life easier. How do I achieve this in PDF?

 

Thanks for the support.

Thanks @APK33396881raev .

 

As already mentioned in the post,

It throws me an error as below 

 

this.getPageNum(pageNum) is not a function

Also tried,

this.getNthPage(pageNum) is not a function

 

Is there any alternative to get exact content which matches regex from page..

 

I want content from whole file which matches regex, which I can loop through and not necessarily from page by page.

 

Please suggest.

You must create loops over all words in the file.

Read the documentation in the Acrobat Javascript Reference.

Also tried the getPageNthWord() function. so that I can iterate through all the words and match each word with regex. but getPageNthWord() omits the special character like (.) dot, # etc. 

 

Is there any alternative with this logic.? Please suggest

 

// Iterate through all pages of the PDF

 

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

 

    var numwords = this.getPageNumWords(pg);

 

    for (var i=0; i < numwords; i++)

    {

        console.println(this.getPageNthWord(pg,i));

    }

 

}
