[CS3 JS] Finding paragraph containing table

[frameexpert]

I have a table object and want to find the paragraph that contains the table. Then I want to return the contents of the paragraph previous to the table anchor. I am using this, but when I attempt to display the contents of the paragraph, I get "Object is invalid". Thanks for any help you can provide.

// Get the paragraph inside the table.

var oPgf = app.selection[0].paragraphs[0];

// Make sure the paragraph is in a cell.

if (oPgf.parent.constructor.name === "Cell") {

  // Get the parent cell and table objects.

  var oCell = oPgf.parent;

  var oTbl = oCell.parent;



  // Get the paragraph containing the table.

  var oPgf2 = oTbl.storyOffset.paragraphs[0];

  // Get the story object of the paragraph.

  var oStory = oPgf.parentStory;

  // Get the paragraph's index.

  var iPos = oPgf2.index;



  // Display the contents of the paragraph before the table anchor.

  alert (oStory.paragraphs[iPos-1].contents);

}

That's because the index is a count of the characters in the story. You need:

alert(oStory.characters[iPos-1].paragraphs[0].contents);

OK, I think I get it. How do I get the index of the paragraph so I can loop through the paragraph's previous to the table? Thanks.

I found a previous post that is helping me with this.

// Paragraph inside of table.

var oPgf = app.selection[0].paragraphs[0];

// Make sure the paragraph is inside a table

if (oPgf.parent.constructor.name === "Cell") {

  var oCell = oPgf.parent;

  var oTbl = oCell.parent;

  // Get the paragraph containing the table anchor.

  var oPgf2 = oTbl.storyOffset.paragraphs[0];

  // Loop from the table anchor to the top of the story.

  while (oPgf2) {

    $.writeln(oPgf2.constructor.name);

    oPgf2 = oPgf2.parentStory.paragraphs.previousItem(oPgf2);

  }

}

This basically works, except this line gives an "Object is invalid" error when it gets to the beginning of the story:

oPgf2 = oPgf2.parentStory.paragraphs.previousItem(oPgf2);

I can use a try statement, but I am wondering why the loop doesn't exit gracefully without an error. Thanks.
