Question

I have a grid loaded, I want to get the current stores URL which loaded the json data to it , and pass an extra param to it, and load this URL as a pdf, or xls. But how can I get the url?

Answer 1

Get the proxy and ExtraParams:

var url = grid.getStore().getProxy().url;
var params = grid.getStore().getProxy().extraParams;

Then, build the url:

var newUrl = url + '?' + Ext.Object.toQueryString (params);

And the newUrl will be something like this:

your_url_data.json?param1=value1&param2=value2

I don’t think that exists a proxy method that do this but you can extend an existing proxy, as follows:

Ext.define ('MyProxy', {
    extend: 'Ext.data.proxy.Ajax' ,
    buildInternalUrl: function () {
        return this.url + '?' + Ext.Object.toQueryString (this.extraParams);
    }       
});

And then:

var newUrl = grid.getStore().getProxy().buildInternalUrl ();

Result is the same 😉

Here’s you can find the doc of proxies: Ajax Proxy
