Answer 1

There are some JavaScript SOAP client libraries out there:

• jQuery SOAP Client
• JavaScript SOAP Client

Those libraries will allow you to easily make a SOAP Request and handle the results.

Answer 2

I strongly suggest that you implement the SOAP client on your web domain. Let the JS call your server, which in turn calls the ASMX. The response of the web service should then be converted to a suitable JSON on your server before sending it down to the client.

This way, you get rid of your cross-domain problems, you don't load a SOAP client in the browser, you transmit less wordy data to the client, and you have the option of caching web service calls at your server to speed things up if you want to.
