I am using this code to embed Google Analytics in the document head from a javascript widget, users will be embedding on their page. But is Google Analytics is not receiving data.

Answer 1

Use script2.text = "..." or script2.innerHTML = "..." instead of script2.value = "...".

Here’s a jsfiddle that tests using all three assignments with the following code: http://jsfiddle.net/7nsGp/

var script2 = document.createElement( 'script' );
script2.value = 'alert("assign value worked");';
$('head').prepend(script2);

var script1 = document.createElement( 'script' );
script1.text = 'alert("assign text worked");';
$('head').prepend(script1); 

var script0 = document.createElement( 'script' );
script0.innerHTML = 'alert("assign innerHTML worked");';
$('head').prepend(script0); 

On both Chrome and Firefox, assigned either .text or .innerHTML, but not .value.

Suggestion: Verify that your script snippet is executing by appending an alert('script ran') to the end of your script text during testing.

script2.value = "var _gaq = _gaq || []; ... ; alert('script ran');";
