change filename into link

i want change filename of link indesign. example: existing filename table_ex.jpg , want change table_cz.jpg

 

i wrote script, seems change 1 link. can me?

 

 

 

#target indesign

// relink file filename.js

  

if (app.documents.length == 0) {

     err("no open document. please open document , try again.", true);

}

 

var mydoc = app.activedocument;

var mylinks = mydoc.links;

var mycounter = 0;

 

if (mylinks.length == 0) {

     err("this document doesn't contain links.", true);

}

    

for (i = mylinks.length-1; >= 0 ; i--) {

     var mylink = mylinks[i];

     var myoldfilename = mylink.name;

     var mynewfilename = myoldfilename.replace("_ex", "_cz");

     var mynewfile = new file(mynewfilename);

     if (mynewfile.exists) {

          mylink.relink(mynewfile);

          mycounter++;

     }

}    

 

document.save()

document.close()

probably relinking messes mylinks collection saved earlier.

 

a quick fix might to place line inside for..loop:

 

mylinks = mydoc.links;

 

.. it's kind of dirty trick. suppose loop keep working. if not, you'll have use infinite loop , keep on checking start, until made no change.
