javascript - Copy to clipboard with break line

Question

I want to copy a text to clipboard but in a new line.

Problem:

If you click the button in the snippet and paste in the notepad this is what you gonna get:

Name: testSurname: testEmail: [email protected]: testCity: testCountry: nullAd Category: testPlan: nullWebsite: Company name: testΜ?νυμα: test

What I want:

I want, if possible, to copy text in a newline. The same as it is when you copy it:

Name: test
Surname: test
Email: [email protected]
...

function copyToClipboard(element) {
  var $temp = $("<input>");
  $("body").append($temp);
  $temp.val($(element).text()).select();
  document.execCommand("copy");
  $temp.remove();
}

$( "#FailCopy" ).click(function() {
  alert("Well done! div #error-details has been copy to your clipboard, now paste it in the notepad or email!");
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>

<!--text that i want to copy-->
    <h2>Div #error-details: the text I want to copy to clipboard:</h2>
    <er id="error-details">Name: test<br>Surname: test<br>Email: [email protected]<br>Address: test<br>City: test<br>Country: null<br>Ad Category: test<br>Plan: null<br>Website: <br>Company name: test<br>Μ?νυμα: test</er>

    <br><br>
    
    <button id="FailCopy" type="button"  
     onclick="copyToClipboard('er#error-details')">Copy div to clipboard</button>

Answer 1

You have a few problems with the code.

First problem in your code is the $(element).text()jquery text() strips your code from html including the <br> tags. So there is no newlines in the clipboard text since all html newlines are stripped away.. so nothing to replace.

If you want to keep <br> as newlines you need to use .html() and parse your text more manually.

Second problem is that you use <input> tag. <input> tag is only single lines so u cant have any newline in there. you need to use <textarea> for the conversion.

The last problem is as above that you also should use for windows users.

I updated your snippet with a working version.

function copyToClipboard(element) {
  var $temp = $("<textarea>");
  var brRegex = /<brs*[/]?>/gi;
  $("body").append($temp);
  $temp.val($(element).html().replace(brRegex, "
")).select();
  document.execCommand("copy");
  $temp.remove();
}

$( "#FailCopy" ).click(function() {
  alert("Well done! div #error-details has been copy to your clipboard, now paste it in the notepad or email!");
});

<!--text that i want to copy-->
    <h2>Div #error-details: the text I want to copy to clipboard:</h2>
    <er id="error-details">Name: test<br>Surname: test<br>Email: [email protected]<br>Address: test<br>City: test<br>Country: null<br>Ad Category: test<br>Plan: null<br>Website: <br>Company name: test<br>Μ?νυμα: test</er>

    <button id="FailCopy" type="button"  
     onclick="copyToClipboard('er#error-details')">Copy div to clipboard</button>
