Dear Professionals ..

I wrote very simple code to search for any numbers and put them into brackets and the GREP code is working in Find/Change but not in javascript at all and no errors

app.findGrepPreferences=app.changeGrepPreferences=null;
app.findGrepPreferences.findWhat="(\d+)";
app.changeGrepPreferences.changeTo="($1)";
app.activeDocument.changeGrep();

So Whats Wrong i  do? 

Best Regards

Hi medos20,

Obviously your grep will not find digit because in JavaScript String "(\d+)" will act like "(d+)" because first slace will act like escape character, So you can change your grep to "(\\d+)".

Try this code sample:

 

app.findGrepPreferences=app.changeGrepPreferences=null;
app.findGrepPreferences.findWhat="(\\d+)";
app.changeGrepPreferences.changeTo="($1)";
app.activeDocument.changeGrep();

Hi Mohammad,

there is a simple way to debug your GREP expression. Just run e.g. this code on InDesign:

app.findGrepPreferences.findWhat="(\d+)";

Then go to InDesign and open the GREP Find/Change panel in the GUI.

You'll see that in the find field there is just d+ visible and not the pattern you want: \d+.
