Question

I am having “SyntaxError: Unexpected token ILLEGAL” error on chrome.

<?
$data = "this is description
         new line";
?>

$(".gantt").gantt({
  desc: "<? echo $data; ?>"
});

the error is between “this is description” and “new line”. Why I cant use enter there? Is there a way to awoid this?

Answer 1

You can’t have (unescaped) new lines in JavaScript strings.

You are outputting:

$(".gantt").gantt({
  desc: "this is description
         new line"
});

The new line after description isn’t valid.

You need to json_encode your value (yes, json_encode works on plain strings too).

$(".gantt").gantt({
  desc: <? echo json_encode($data); ?>
});

Note that I removed the quotes. json_encode will add quotes for you.
