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.
