Aways getting '$' not defined, 'CheckIfBrowserHasPopupBlock'

It is mandatory to add Jquery reference to your page if want to use anything with jquery. You can do this by adding link of CDN directly or can download that js file and save that in your project locally, than add refernce of that.

 

For other errors, please show your code here for html file and jquery function so that I can check that.
