How to modify this script to target the current textbox or selection

Question

This script fills empty cells of a table with a certain character (e.g. -).It now affects the entire document.Would anyone like to help modify it by adding the options: whole document, current article, current selection?Thanks a lot. var myDocument = app.documents.item(0);
var myStory = myDocument.stories;
for (var s=0; s<myStory.length;s++){
var myTable = myStory.item(s).tables;
for (var t=0; t<myTable.length;t++)
for (var i=0; i<myTable[t].columns.length; i++){
for (var j=0; j<myTable[t].columns.item(i).cells.length; j++){
if (myTable[t].columns.item(i).cells.item(j).contents == ""){
myTable[t].columns.item(i).cells.item(j).contents ="—"; //The character you want to fill
}
}
}
}

The internal two loops - as you are going through all cells anyway - you can just loop through the cells of the Table:

for (var j=0; j<myTable[t].cells.length; j++)
{
  if (myTable[t].cells.item(j).contents == "")
  {
    myTable[t].cells.item(j).contents ="—"; //The character you want to fill
  }
}
