Even if you don't have jQuery loaded, the function $() is now defined by Google Chrome as something similar to querySelectorAll(). This function only accepts a CSS selector as parameter and not arbitrary HTML like jQuery's $(). From the docs: SYNTAX_ERR code 12 In invalid or illegal string has been specified; for example setting the selectorText property of a CSSStyleRule with an invalid CSS value. The function is expecting a CSS selector and you gave it HTML so it gave a syntax error. See this fiddle, it works just fine: http://jsfi(more…) IE7 FF1.5+ SA1.3+ OP9+ None Full Full Full Examplevar node = document.getElementsByTagName('h1').item(0); var refnode = node.nextSibling; var newnode = document.createTextNode('That is why you fail.'); node.insertBefore(newnode, refnode); The example above shows safari syntaxerror: dom exception 12: an invalid or illegal string was specified. an insertBefore operation that will fail, because refnode is not a child of syntaxerror: dom exception 12 setrequestheader node.

NOT_FOUND_ERR DescriptionThe DOMException interface represents a processing error, for example when trying to create an invalid DOM, or passing a non-existent node as an argument to node manipulation methods. An exception is http://stackoverflow.com/questions/15714601/error-syntaxerror-dom-exception-12-on-tag-creation-using-jquery raised when an operation is impossible to perform, ie. in "exceptional" circumstances. The DOM does not define an exception for every possible error that might occur, for example syntax errors in arguments are not included, and in such cases an implementation will use its own error reporting mechanism to deal with them. : How DOM Exceptions are implemented in modern browsers In practise, what we find http://reference.sitepoint.com/javascript/DOMException is that most browsers implement DOM exceptions as part of their native mechanism, passing the exception code and message as the details of the error, along with any additional information the browser is able to provide (such as line number or stacktrace). Exceptions in JavaScript can be handled using the try...catch...finally construct.

In XML a more informative description will be given — for this example, Insert position Node must be a Child of the Node to insert under. : Caveat for Safari Safari 1.3 and 2 do not report the error name, only the error code. However this is not documented as a bug because the specification does not define error names as properties of the DOMException object. ConstantsThe interface defines ExceptionCode integers — exposed through the code property — to refer to each type of error; these are defined by the following constants:
