Getting dynamic value from 3rd party page and passing to a function on another page

I'm trying to figure out how to grab the PDV_n9559649 value when a sample 3rd party URL is hit:

https://polldaddy.com/n/413dd20f300b3fe5532c4c3b08bf9684/9559649?1477900000003

and renders the following:

PDV_n9559649='c3312b14d3|945';PD_vote9559649(0);

But trying to read into a JS function on my page somehow? Is that even possible with some type of callback function? If not what other alternatives do I have?

No it's not possible to do this on the client (possible security risk and so it is outlawed).  You will need to do this on the server.  As that URL does not return JSON it's not possible to use jsonp (a cross site scripting workaround)

XMLHttpRequest cannot load https://polldaddy.com/n/413dd20f300b3fe5532c4c3b08bf9684/9559649?1477900000003. No 'Access-Control-Allow-Origin' header is present on the requested resource.

Therefore you should use a server side language (such as PHP) to request that URL via cURL or file_get_contents and return that to your page.

You can return that to your page using AJAX
