卷曲调用不执行javascript代码

Question

I have one php page with javascript code socket code to connect to noje.js Server.
That page is called by sms service provider(smsgupshup) through curl.
Now because of this scenario javascript code to connect to node.js server is not working.

My question is simple how can I execute that javascript code when curl call is made to that page.

Thanks in Advance
