Can't delete all section

Hi guys,

Why does ID not allow you to delete all sections.

for ( i = allSections.length; i > 0; i-- ) {

    allSections.remove();

    }

This says undefined is not an object but I have 2 sections in my document.

allSections = doc.sections.everyItem().getElements();

A document must have at least one section with at least one page.

While Peter is right (naturally), it's not the reason why you get that error.

If you have 2 sections, the count is '2' but since counting starts at 0, their indexes are 0 and 1.

You try to remove a section with index 2, which does not exist. So you get that error.

    I read the first sentence and thought that I had seen enough. Clearly not!

      Hi,

      Are these 3 codes equivalent?

      Thanks in advance!

      app.activeDocument.sections.itemByRange(1, app.activeDocument.sections.length-1).remove();
      allSections = app.activeDocument.sections.everyItem().getElements();
      S = allSections.length;
      for ( var s = 1 ; s < S ; s++)  allSections.remove();
      allSections = app.activeDocument.sections.everyItem().getElements();
      for ( s = allSections.length-1 ; s > 0 ; s-- )  allSections.remove();

      Well, Michel, they have the same result so in that sense they're equivalent. The approaches are slightly different. So it depends on what you understand by 'equivalent'.
