SyntaxError: unterminated string literal javascript console

Question

I am creating a Javasript object:

var obj= new Object();
obj.Message = $(".textarea").val();

and posting this object via JSON stringify:

$.ajax({
    type: "POST",
    contentType: "application/json",
    dataType: "json",
    url: 'xx/yy',
    data: JSON.stringify(obj),
    success: function (html) {
        // ...
    },
    error: function (request, status, error) {
        // ...           
    }
});

I am getting:

SyntaxError: unterminated string literal in console

What should I replace?

EDIT:

This issue is specific to data the user enters in plain text area (not rich text area)

You can click the error and it will lead you to the error source line. — Jai

not your issue, but: dataType: "json", with data: JSON.stringify(obj), is wrong ... dataType: "json", data:obj, and you're golden — Jaromanda X

This may be your value of have some line breaks or some invalid string literals. You can replaces line breaks of your textarea's value like this.

var str = $('#textarea1').val();
str = str.replace(/(?:\r\n|\r|\n)/g, '');

This is full code snippet, so that u can check. Hopefully you can escape from "SyntaxError: unterminated string literal" when executing JSON.stringify(obj).

<!DOCTYPE html>
<html>
	<head>
		<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
	</head>
	<body>
		<textarea id="textarea1" rows="4" cols="50">
		</textarea>
		<input type="button" value="Check" id="btnCheck"/>
		
		<script>
			$(document).ready(function(){
			
				$('#btnCheck').on('click',function(){
				
					var str = $('#textarea1').val();
					str = str.replace(/(?:\r\n|\r|\n)/g, ''); 
					var obj= new Object();
					obj.Message = str;
					
					console.log(JSON.stringify(obj));
					
				});
			});
		</script>
	</body>
	
	
</html>
