Hi Eric,

Here is a solution to change service URL in accordance to selected select item:

1. Open "Storage and model" interface.

2. Add "currentRSSUrl" storage with type "string" and storage - "local storage".

3. Add "value change" event handler for needed select. And populate it with following JS code:

   pre

   //Hardcoded value for test.
   var url = "http://cvunews.wordpress.com/?tag=nordic&feed=rss2";

   //Get url from select. Uncoment this line of code when you populated select with URL values.
   //url = jQuery(this).val();

   localStorage.setItem("currentRSSUrl", url);

   /pre

4. open your service.
   4.1. In settings tab use "{currentURL}" in URL field.

   4.2. Navigate to request tab. Open "Query String" sub tab. And add "currentURL" parameter.

5. Open service datasource "before send" mapping.

6. In datasource make link from "currentRSSUrl" storage to "currentURL" request parameter.

7. Invoke service without any parameters(like you did above) when you need.

   That's all.

   Regards.

Thanks very much for the detailed response. I'm pretty sure I have everything set up correctly but it's still not working. Since the selectbox does not allow URL values, I changed the js code slightly and url value alerts correctly.

Is this the proper way to invoke the service?

var url = "https://cvunews.wordpress.com/" + jQuery(this).val() + "/feed/";

localStorage.setItem("currentRSSUrl", url);

CVUNewsService.execute();

Hi Eric,

Please debug this implementation with console.log(); code.

For example to see what actually you have in you your URL processing you can use following JS code:

pre

var url = "https://cvunews.wordpress.com/" + jQuery(this).val() + "/feed/";

localStorage.setItem("currentRSSUrl", url);

console.log("url = " + url);

CVUNewsService.execute();

/pre

Then you can open browser debugger on network tab and take a look what URL requested with service.

Regards.

How did you add the "URL", "Method" and "Response Data Type" fields in the appery service?
