Indesign script to insert new master on every other page

[dsomrz]

I have an indesign document that I have to insert a blank or Master page everyother page. 

Any help is appreciated. Thank you!!

Hello @dsomrz,

Can you try using the following script to see if it helps with your workflow:

// Create a new master spread
var myDocument = app.activeDocument;
var myMasterSpread = myDocument.masterSpreads.add();
var myMasterPage = myMasterSpread.pages.item(0);

// Loop through the pages and apply the master spread to every other page
for (var i = 1; i < myDocument.pages.length; i += 2) {
    myDocument.pages.item(i).appliedMaster = myMasterSpread;
}

Looking forward to hearing from you.

would i copy and paste into script editor or text edit.

Use a plain text editor (not RTF), save as .jsx file then save jsx to script folder in panel.

I don't think this will work since it's not injecting new pages. Try this instead: 

var d = app.activeDocument; 

var ps = d.pages;

var i = ps.length: 

while(i--) { 

     var p = d.pages.add(LocationOptions.AFTER, ps[i]; 

    p.appliedMaster = null;

}

I used the text editor for mac but it doesn't work, changed the extension to .jsx or do i have to use another plain text editor

If you're using TextEdit, then make sure to use the plain text mode. Cmd-Shift-T toggles between plain text and RTF, you'll see right away which mode you're in.

the first one is useful if i want to make everyother page a different master. The second one I get this error. see screen shot.

[brian_p_dts]

Sorry the colon after ps.length should be a semicolon. Coding on phones is hard.

Found a script here that seems to do it

Might be what's here already , haven't checked. 

[dsomrz]

thanks. I saw that but when I click on the link it says safari can not open the page. I tried in Chrome and same thing.

[dsomrz]

thanks I still get an error

var d = app.activeDocument;
var ps = d.pages;
var i = ps.length;
while(i--) {
var p = d.pages.add(LocationOptions.AFTER, ps[i];
p.appliedMaster = null;
}

[brian_p_dts]

Ack, a missing paren too. More coffee before posting and not on mobile : ). This should do it. 

var d = app.activeDocument;
var ps = d.pages;
var i = ps.length;
while(i--) {
var p = d.pages.add(LocationOptions.AFTER, ps[i]);
p.appliedMaster = null;
}

[dsomrz]

AWESOME!. Thanks that work, really appreciate it. Have a good day

Why do you want to do that? If you want to  print left and right, why do you not set up the document with facing pages? This would be the correct way.

[dsomrz]

it was a supplied Indesign document from a customer. I didn't set it up originally.

[Willi Adelberger]

What hinders you to change the setup to facing pages?

[brian_p_dts]

Because they need the facing page to be blank?

[dsomrz]

nothing hinders me from changing it to facing pages. I just want to be able to add a blank page after each page without having to change their file. I can do this in Acrobat, but wanted to know if there was a way to do it in Indesign

[Willi Adelberger]

THe correct way is to set up as facing pages. Inserting pages will also change the document. Set up the facing master, one side empty, the other with text frame and let the text run in.

[dsomrz]

ok, it is a customer supplied indesign file.
