Line break in a message

Question

With Google Apps Script, how to make a line break in a variable to send mail?

Answer 1

You should use the <br> tag when sending the HTML portion of the email .

Below is a sample on how I compose the same email body, but formatted differently for HTML & plain text. (Not the best code but hopefully it illustrates the point)

function onFormSubmit(e) {
  var subject = "Subject";

  // Collect user data
  var name = e.values[0];
  var email = e.values[1];   // Where user enters his/her email address

  // Generate content - Replace this with what you're composing
  var content = [];
  content.push("Hi " + name);
  content.push("Thanks for submitting the survey!___LINE_BREAK___");
  content.push("Survey Team");

  // Combine content into a single string
  var preFormatContent = content.join('___LINE_BREAK___');

  // Replace text with \n for plain text
  var plainTextContent = preFormatContent.replace('___LINE_BREAK___', '\n');
  // Replace text with <br /> for HTML
  var htmlContent = preFormatContent.replace('___LINE_BREAK___', '<br />');

  MailApp.sendEmail(email , 
                    subject, 
                    plainTextContent ,                    
                    { 
                      name: "Survey Team", 
                      html: htmlContent 
                    });  
}

Answer 2

If you're not sending an HTML formatted message, use "\n". I personally despise HTML formatted e-mail.

Answer 3

Newline in msgBox:

Browser.msgBox('line 1 \\n line 2');

Please note you need to escape '\n' with additional backslash.

Answer 4

I usually use table in my mail but I think <br /> should work
