Assigning a paragraph-style in a loop

[cmoke73]

Hi everybody.

I have a simple task: select some items in a document and assign to the penultimate paragraph a style in a for-loop.

var doc = app.documents;  
var Auswahl = app.selection[0];
var eineAuswahl = app.selection;
var Anzahl = Auswahl.paragraphs.count();
var Durchgaenge = eineAuswahl.length;
for (var x=0; x<Durchgaenge; x++) {
    //alert (eineAuswahl.paragraphs.count());
        var FormGrup_SF_Artikel = app.activeDocument.paragraphStyleGroups.itemByName('SF_Artikel');
        var AbsForm_SF_Art_Tx_2_Abst = FormGrup_SF_Artikel.paragraphStyles.itemByName('SF_Artikel_Text_2_Artikel_mehr Abstand');
        var letztArt = Auswahl.paragraphs.item(-2);        
        letztArt.appliedParagraphStyle = AbsForm_SF_Art_Tx_2_Abst;  
}

After running the script it stops. The error-message ist: "Object does not support the property or method '0'". What does it mean?

When it runs without a loop (assign only to one object), it works:

 var FormGrup_SF_Artikel = app.activeDocument.paragraphStyleGroups.itemByName('SF_Artikel');
        var AbsForm_SF_Art_Tx_2_Abst = FormGrup_SF_Artikel.paragraphStyles.itemByName('SF_Artikel_Text_2_Artikel_mehr Abstand');
        var letztArt = Auswahl.paragraphs.item(-2);        
        letztArt.appliedParagraphStyle = AbsForm_SF_Art_Tx_2_Abst;

In the first script, you have

letztArt = Auswahl

but

Auswhal = app.selection[0];

so what do you mean by

app.selection[0][0]

when x == 0 ??

Try it without the !

I need the var x to change the paragraph in EACH of the selected text frames. If I try without it changes only the first of the selected objects. x stands for "next selected object".

Again: In line 11 of the first script you have

     var letztArt = Auswahl.paragraphs.item(-2);         

The first time the loop is entered, x = 0.

So you're trying to access this property:

app.selection[0][0]

That property does not exist. Hence the error message.

Okay. Sorry, now I´ve got it: I have to use

var letztArt = eineAuswahl.paragraphs.item(-2);

Thank you! Now it works.

Hi,

So....:

var letztArt = eineAuswahl.paragraphs.item(-2);
