[Muhammad_eloc]

Hi all,

i need to change Left cell inset value with Right cell inset on all tables with all cells

Thanks in Advance

Show your code. What have you tried so far?

hey Vamitul,

i tried this code

app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().rightInset = "3mm"

app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().leftInset = "4mm"

but in case i have many tables with different values then i can't unify same values to all tables, i need to read left inset and reverse it to right inset

Thanks

This ought to get you up and running:

As you may already know, these properties are called 'leftInset' and 'rightInset'; exchanging them should be easy (but take care to use a temporary variable in between).

Thanks Jongware for this link it helps me a lot for another things , but this

[Vamitul]

(function(){
  try {
  var cells=app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().getElements();
  for (var i=0; i<cells.length;i++){
  var l=cells.leftInset;
  cells.leftInset=cells.rightInset;
  cells.rightInset=l;
  }catch(e){

  }
  }
}())

sorry, mistyped a bracket there:

(function() {
        try {
            var cells = app.activeDocument.stories.everyItem().tables.everyItem().cells.everyItem().getElements();
            for (var i = 0; i < cells.length; i++) {
                var l = cells.leftInset;
                cells.leftInset = cells.rightInset;
                cells.rightInset = l;
            }
        } catch (e) {


        }
}())

Fine! Thanks Vamitul!

Vamitul,

I've 2 questions:

• Why do you place the "function" between two parenthesis?

• Is the "try … catch …" truly useful here?

Thanks in advance!

the (function(){}())  pattern is called and self-executing anonymous function. Because javascript has function-based scope, it is used to isolate the variables in the script as not to pollute the global namespace. While in this, and many other simple scripts is not really needed, since the engine in which the script runs is not persistent, it does not hurt and it's a good habit to get into for when you start to write much larger scripts. There are quite a few resources about this online, for example: http://stackoverflow.com/questions/14322708/what-is-self-executing-anonymous-function-or-what-is-thi...

The try-catch here is very useful here:

consider what happens if a document has no tables:

app.activeDocument.stories.everyItem().tables.everyItem() returns and empty specifier, that has no "cells" object, so you would get an error. Or, taking things to a bit more extreme, what if there is no document opened? I agree it's not the nicest, most elegant or expressive way of doing it, but it works in a pinch (to be read as: don't do as i do).

Thanks a lot for these explanations!
