Uncaught SyntaxError: Unexpected token ILLEGAL in jQuery

Question

Running Splunk examples and I get an error in this function.

var injectCode = function(code) { var sTag = document.createElement("script"); sTag.type = "text/javascript"; sTag.text = code; $(head).append(sTag); return sTag; }

The exact error is in $(head).append(sTag); . This is placed inside a Jade file and it's running on Node. What am I doing wrong here?

EDIT - Sorry, head is defined as var head = $("head");right above the function.

And code comes from this function

var getCode = function(id) { var code = ""; $(id + " pre li").each(function(index, line) { var lineCode = ""; $("span" ,line).each(function(index, span) { if ($(span).hasClass("com")) { lineCode += " "; } else { lineCode += $(span).text(); } }); lineCode += "\\n"; code += lineCode; }); return code; }

Are you sure head exists? Maybe it should be document.head? — gen_Eric

Shouldn't there be quotes around head, like $("head").append(sTag); — tymeJV

head is a tag, use that:

$('head').append(sTag);

EDIT:

I would say remove this:

lineCode += "\\n";

This is placed inside a Jade file and it's running on Node. - is there something in Node/Jade that defines head that would let this work before your change? And you wouldn't get the exception that the OP is reporting if you used $(head) and head wasn't defined

@Ian ya true but i don't know what kind of error OP is talking about. Oops sorry, Ian, i saw the title now... Unexpected token ILLEGAL in jQuery

Try to exchange lineCode += "\\n"; for

lineCode += "\n";

I assume you're dealing with a code string (to which you want to add a newline), not a string literal string (to which you want to add the \n literal).
