How to consume webservice in javascript

Question

please tell me how to consume webservice (.net) using javascript.

its SOAP.

Thanks

Answer 1

You use AJAX.

In particular the XMLHttpRequest object.

Look at the jQuery ajax API - it makes AJAX easier to use.

Answer 2

I don't think there is a Javascript library that consumes SOAP out of the box. Dojo offers a lot of functionality in that direction, RPC-calls for example, and is probably the one that comes closest. IBM did some work there that you might want to check out.

This (including Dojo) is a lot of non-trivial stuff to learn but SOAP is a nasty beast, if you really need to interface to a SOAP service with JS you will have to invest some time.

See:

Answer 3

Both .asmx and .svc (wcf) expose javascript enabled bindings - this is easy to find on the internet.

Example:

Normally you just append /js to the url of the endpoint and javascript providing a proxy is returned.

This proxy code relies on the ASP.NET AJAX framework, but you can easily use it with any other ajax-enabling framework by using this shim .
