CS3 Javascript - finding the paragraph which contain the index page reference

Yes, it work's very well with the backslashes, thank you very much for your very efficient help.

Br Scubilion,

It is true that JavaScript doesn't know about lookbehind, but as you're using InDesign's GREP, not JavaScript's, that's not the problem: InDesign does know lookbehind. The problem in your code is probably that you forgot to escape the backslashes. Please try the following:

"(?<=~b)\\u{1,2} \\d{1,2}"

I just assume that this should be done in VB: I know it should in JS, but as I don't know much about VB I'm guessing here.

Sorry, I'm not sufficiently familiar with VBScript to help you on that one. I have seen it mentioned here before (now that you bring it up). A search of this forum might help, or a VB-knowledgeable person might drop by.

Dear Sir,

I realize that the response to my snd question was in your first response, excuze me, I long to understand. In javascript, your code works very well. But in vbscript, there is a problem :
myStory.characters.itemByRange(0,myLine.index) don't give a text but a collection of characters, and I can't ask for ".texts(0).lines.length", it give me an error.

if I select the collection, like thereafter, I get an error because myselection isn't a text object !

myselection = myStory.characters.itemByRange(0,myLine.index).select
myselection.texts(0).lines.length.

And I can't use javascript, because my Grep search text "(?<=~b)\u{1,2} \d{1,2}" contains a lookbehind option that javascript doesn't understand !
Do you have another solution ?
Br. Scubilion

The index property of a text object is the index within the story. So, if you want the offset of a text object within some other entity, you have to do it by comparing the values of the indexes of the two entities (although, in the case of a text frame, you want the index of the first character of the frame, not the frame itself).

Dave

Thank you, Mr Dave Saunders, for your prompt response.
Just another question :
How could I get the index of the line of a grep search result, in his parent story, textframe, paragraphe, or text.
thanks
Br Scubilion

What you're getting is correct. All text objects return as their index property the index of the first insertion point within the text object relative to the start of the story. If you want the count of lines in the story up to and including the first line of result(1) use (JS):

myStory = result(1).parent;

myLine = result(1).lines[0];

lineCount = myStory.characters.itemByRange(0,myLine.index).texts[0].lines.length;

Hello,
I'm French user of Indesign CS3. Please, be forgiving for my poor English.
'b I've a problem when I try to get the index of a line in a Story.
Dim myindesign As InDesign.Application

Dim maselection As InDesign.Story
Dim mydocument As InDesign.Document
Set myindesign = CreateObject("InDesign.Application.CS3")
Set mydocument = myindesign.ActiveDocument
Set maselection = myindesign.Selection(1).ParentStory
myindesign.FindGrepPreferences = idNothingEnum.idNothing
myindesign.ChangeGrepPreferences = idNothingEnum.idNothing
myindesign.FindGrepPreferences.FindWhat = "(?<=~b)\u{1,2} \d{1,2}"
Set result = maselection.FindGrep(False)

If I try to get the line index of the first result like that :
myline = result(1).lines(1).index
myline is the index of the insertion point of the first characters of the result !
I can understand Vbscript and javascript code.
Thank you for your help.

If you want get the paragraph n-th

//1st:
story_ix_para_obj = {};
story_para_ix_obj = {};

//2nd:
story = myText.parentStory;
id = story.id;
if(!story_para_obj[id]){
story_para_obj[id] = {};
paras = story.paragraphs;
paras_len = paras.length;
for(i = 0; i< lim; i++){
story_para_obj[id] = paras;
story_para_ix_obj[paras.toSource()] = i;
}
}

//third:
this_para_start = myText.paragraphs[0];
this_para_end = myText.paragraphs[-1];

//fourth:
this_page_start = -1, this_page_end = -1;
if(this_para_start == this_para_end){
//do some thing, get para_ix/get ix_para
}else{
//do some thing, get para_ix/get ix_para
}

//fifth: combine 1-4 into index's function
