Question

I have the following querystring (where kvks is dynamic):

http://api.openkvk.nl/json/SELECT bedrijfsnaam FROM kvk WHERE kvks = 27312152 LIMIT 1;

If you execute this querystring, it will return json data.
What is the best approach to handle this? I tried it in this way, but nothing alerts

url.append("http://api.openkvk.nl/json/SELECT bedrijfsnaam FROM kvk WHERE kvks = ");
url.append(Dossierno);
url.append(" LIMIT 1");

$.get(url, function (data) {
            alert(data); });

Or should I handle this in a separate aspx page?

$.get('getaddress.aspx', { sDossierno : Dossierno} function (data) {
            alert(data); });

If yes, how can I send a querystring and return the json object on the getaddress aspx page?

Answer 1

That’s not query string that you have. It’s part of the uri and ASP.NET won’t probably allow it. You may try the following:

$.get( 
    'http://api.openkvk.nl/json', 
    { q: 'SELECT bedrijfsnaam FROM kvk WHERE kvks = ' + Dossierno + ' LIMIT 1' }, 
    function (data) {
        alert(data); 
    }
);

where the corresponding server side script will read the q query string parameter.

Also I hope you are aware of the implications in terms of security of having a server side script which accepts what seems to be a SQL query and executes it against a relational database. And last but not least don’t forget about the same origin policy restriction and make sure that this script is hosted on http://api.openkvk.nl if you intend to send AJAX requests to it.
