then, run the loaded function and gives the function undefined error. The files are loaded and added to head section in chrome console. The reference said dynamic loading functions are relied on the browser. I tried $.getScript() and DOM to add elements but it does not work.
var head= document.getElementsByTagName('head');
var script= document.createElement('script');
Please tell me how to fix the errors. Or how to call function properly, for misplacement.
