How to include external source in js files in siebel open ui

Hi,

I want to include the external source file path/url in postload.js file. What is the syntax ? We are using 8.1.1.14

I want the below src file for the div id piechart

"https://www.google.com/jsapi?autoload={%27modules%27:[{%27name%27:%27visualization%27,%27version%27:%271.1%27,%27packages%27:[%27corechart%27]}]}"

  $("#s_S_A5_div").after('<div id="piechart" style="width: 900px; height: 500px;"></div>')

Thanks.
