How to change url in jsonp proxy?

[hebr3]

I define a jsonp proxy to read data out of iTunes, the url is
http://itunes.apple.com/search?entity=album&term=... (... is the search string)
It works for a given search string.

How can I set the url dynamically. I tried to use the beforeload event with store.setProxy, but I do not manage to replace the url in the network call.
Is there an automatic way of passing parameters to the store/proxy so that the proxy handles the url extension?

Best regards

Have you tried using the setUrl method on the proxy?

I don't find the setUrl-method, does it really exist?

I did now

...
    var p=this.getProxy().getInitialConfig();
    p.url = 'http://itunes.apple.com/search?entity=album&attribute=allArtistTerm&term='+searchValue;
    this.setProxy(p);
...

I've searched the docs and haven't found a method named setUrl for proxies (or getUrl for the matter). If one does exist that'd be great.

All properties in the config object in all classes get a setter and getter created. If you look at Ext.data.proxy.Server url is in the config object so it has a setUrl and getUrl method created for it. Ajax and JsonP proxy extends Server proxy, in buildRequest (where the url is used) it executes the getUrl which simply returns the _url propery that the setUrl will change so it should always update to use the new url.

I understand assuming config options have mutators and accessors; I'm just saying that if there were documentation included for those getters and setters, and a majority does, then some questions like these could be prevented, at least for those users who turn to the docs before the forum.

I was having the same problem and after few hours of try and errors and found a solution:

//get the store
var store =Ext.getStore('myLittleStore');

//get the store proxy
var proxy=store .getProxy();

//change the url
proxy.setUrl('new url go here');

//re-load the store with new data
store .load();
