I use AJAX to get the content of a script, and then use the following code: var scr = document.createElement('script'); scr.appendChild(document.createTextNode(script)); // *** document.getElementsByTagName('head')[0].appendChild(scr); Where `script` is astring populated from AJAX. This works fine in IE9, Chrome and Firefox. However, in IE6 and 7 I get an error: > Unexpected call to method or property access IE gives the number of the the line indicated with the `// ***`. Although there are multiple other questions about this, none of the appear to address this precise issue.
