[HELP JAVASCRIPT] Delete in a table the texts containing a "Yy" prefix

[Muzan5EC8]

Hello,

Is it possible to help me with a program?

I would like to delete in a table all the texts containing a "Yy" prefix like the words "Yycar", "Yytravel", etc...

I developped a code but it doesn't seem to work at runtime, if you have a track I will be totally grateful to you 🙂

Here is my code:

// recovery. of all <td> 
const oCells = document.querySelectorAll("table td");
const search = "Yy";
// the search loop
for (let cell of oCells) {
  const text = cell.textContent;      // reading raw content
  if (text.startsWith(search)) {      // occurrence found
    cell.textContent = " ";       // we replace the content with nothing
  }
}

This JavaScript code will be used on a PDF document containing a table with data and I would like to delete in this table all the texts containing the prefix "Yy". 

Thanks in advance for your reply and have a nice day!

Do you have a solution in this case?

[Test Screen Name]

Not sure what case this is...

- you have a question about browsers but you are in the wrong place?

- you want to work in Acrobat but have the wrong JavaScript?

Please let us know.

I will explain my case.
I first on Word generate a table pre-filled with data using a macro. Following this I exported my table as a PDF file.
And I have a javascript function which allows to remove all the fields from my table which do not contain the "Yy" prefix.

Now what I will need is to remove the texts containing the prefix "Yy" which are placed in front of the fields so that they only have the text. And when I say delete the texts, it means replacing the text with "".

Here is my table :

 I used field recognition to make all fields appear in the table. Then with a javascript function I deleted all the fields not containing the "Yy" prefix as you can see.
And now I would like to delete the texts in front of the fields.

Here is the code to delete all the fields not containing the "Yy" prefix :

for (var i=this.numFields-1; i>=0; i--) { 
    var f = this.getField(this.getNthFieldName(i)); 
    if (f==null) continue; 
    if (/^Yy/.test(f.name)) continue;
    this.removeField(f.name); 
}

Acrobat Javascript can't change the text in PDF files. Can't you change the text in the Word document?

[Muzan5EC8]

Unfortunately not because as I say on word I created a pre-filled table with data in some cells starting with "Yy". And the cells contain names for that when I export my file to PDF. The fields automatically take the name of the cell data with the field recognition tool.

If Acrobat Javascript can't change texts in a PDF document, can it at least hide / hide them?

[Muzan5EC8]

I forgot to specify I am on Foxit PhantomPDF and I can modify the texts of a PDF on it.

Like this :

But I would like to automate this action with JavaScript ...

Try a forum for Foxit PhantomPDF.

Ok thanks for your answer, I will do that.
