I want a break line in Subject. The output I need is:

Answer 1

Add %0D%0A to any place you want to encode a line break on the URL.

• %0D is a carriage return character
• %0A is a line break character

This is the new line sequence on windows machines, though not the same on linux and macs, should work in both.

If you want a linebreak in actual javascript, use the \\n escape sequence.

Answer 2

Here you are ;-)

<script type="text/javascript">
    alert("Hello there.\nI am on a second line ;-)")
</script>

Answer 3

I was facing the same problem. For my solution, I added br enclosed between 2 brackets < > enclosed in double quotation marks, and preceded and followed by the + sign:

+"<br>"+

Try this in your browser and see, it certainly works in my Internet Explorer.

Answer 4

alert("I will get back to you soon\nThanks and Regards\nSaurav Kumar");

或url中的％0D％0A

Answer 5

Using + "<br>" + between each point you want to break may work for you.

eg

 var numberTimes = 5; for(var times = 0; times < numberTimes; times++) { document.write("Number of times executed: " + times + " " + "<br>"); } document.write("It's over.")
