Retrieve all content before split

I am trying to forward an email and add a paragraph after the 6th paragraph in the original message which looks like this:

p1
p2 
p3
p4
p5
p6
p7
p8
p9

I have this script (only part of it is shown below):

var body = messages[j].getPlainBody();
var firstpart = body.split("\n")[7,8,9]);
var secondpart = body.split("\n")[1,2,3,4,5,6]);
GmailApp.sendEmail(recipient,subject, '', {htmlBody: "blabla" + body});

Instead of this, I would like to have something like that:

var body = messages[j].getPlainBody();
var firstpart = body.split("\n")[7,8,9]);
var secondpart = body.split("\n")[1,2,3,4,5,6]);
GmailApp.sendEmail(recipient,subject, '', {htmlBody: firstpart + "blabla" + secondpart});

This does not work, as the split returns only one paragraph. Is there a way to include all first 6 paragraphs and all last paragraphs in variables?

Many thanks in advance!

You could do a regex replacement here:

var input = "p1\np2\np3\np4\np5\np6\np7\np8\np9";
var output = input.replace(/^((?:[\s\S]*?\n){6})/, "$1blabla\n");
console.log(output);

I believe your goal is as follows.

  • You want to insert a value of "blabla" in the text of body.

  • From your script of Instead of this, I would like to have something like that:, you want to achieve the following result.

      p7
  p8
  p9
  blabla
  p1
  p2
  p3
  p4
  p5
  p6

In your situation, how about the following modification?

Modified script:

var body = messages[j].getPlainBody();
var p = body.split("\n");
var res = [...p.slice(6, 9), "blabla", ...p.slice(0, 6)].join("\n");
GmailApp.sendEmail(recipient, subject, '', { htmlBody: res });

  • When this script is run, the above result is obtained.

  • If you want to retrieve the following result,

      p1
  p2
  p3
  p4
  p5
  p6
  blabla
  p7
  p8
  p9

    • Please modify var res = [...p.slice(6, 9), "blabla", ...p.slice(0, 6)].join("\n"); as follows.

        var res = [...p.slice(0, 6), "blabla", ...p.slice(6, 9)].join("\n");

Note:

  • In your script, htmlBody is used. If you want to use the result value as HTML body, please modify join("\n") to join("<br>").

  • As an additional information, if your value of body is more than 9 paragraphs and you want to include all paragraphs, how about modifying var res = [...p.slice(6, 9), "blabla", ...p.slice(0, 6)].join("\n"); and var res = [...p.slice(0, 6), "blabla", ...p.slice(6, 9)].join("\n"); as follows?

    • var res = [...p.slice(6), "blabla", ...p.slice(0, 6)].join("\n");
    • var res = [...p.slice(0, 6), "blabla", ...p.slice(6)].join("\n");

Added:

From your following reply,

Input: <br>p1<br>p2<br>p3<br>p4 Output at goal: <br>p1<br>p2<br>blabla<br>p3<br>p4 Output I actually get: p1 p2 blabla p3 p4 I miss the <br> in my output, but I WANT them.

In this case, how about the following sample script?

Sample script:

var body = "<br>p1<br>p2<br>p3<br>p4";
var p = body.split("<br>");
p.splice(3, 0, "blabla");
var res = p.join("<br>");
console.log(res) // <br>p1<br>p2<br>blabla<br>p3<br>p4

  • When this script is run to your sample input of <br>p1<br>p2<br>p3<br>p4, you can see the sample output value of <br>p1<br>p2<br>blabla<br>p3<br>p4 you expect.
