Forgive me if this is a simple problem but I can't seem to find why this code:

function create_content(c)
        {
            var html = "<div id='header'>"+c+"</div>";
            if(c == "links")
            {
                var ul = "<ul><li><a href=''>My Link 1</a></li>
<li><a href=''>My Link 2</a></li></ul>";
                html = html + ul;
            }
            return(html);
        }

Is giving me this error in Chrome (win):

Uncaught SyntaxError: Unexpected token ILLEGAL

On the line that starts with "var ul = "

Any advice would help thanks!

• This question is similar to: How can I assign a multiline string literal to a variable?. If you believe it’s different, please edit the question, make it clear how it’s different and/or how the answers on that question are not helpful for your problem. – dumbass Commented Jan 22 at 7:01

You are inserting a line break in your ul string, between the closing </li> and the opening <li>. JavaScript string literals cannot span multiple lines like this by themselves, unless you

• Trail a \ at each line but the last (as Ivo Wetzel says):

  var ul = "<ul><li><a href='http://www.mylink.'>My Link 1</a></li>\
  <li><a href='http://www.mylink2.co.uk'>My Link 2</a></li></ul>";
  

• Break them and concatenate the parts, like this:

  var ul = "<ul><li><a href='http://www.mylink.'>My Link 1</a></li>";
  ul += "<li><a href='http://www.mylink2.co.uk'>My Link 2</a></li></ul>";
  

  (To keep the newline there you would place a \n somewhere, but in HTML it won't matter.)

I found I needed to escape the forward slashes in my closing tags. ie;

<\/script>

or

<\/form>

Then the "Uncaught SyntaxError: Unexpected token ILLEGAL" Error went away and my code processed fine.
