prototype+json ajax应用
Using JSON with AjaxUsing JSON with Ajax is very straightforward, simply invoke String#evalJSON on the transport’s responseText property:
new Ajax.Request('/some_url', { method:'get', onSuccess: function(transport){ var json = transport.responseText.evalJSON(); } });
If your data comes from an untrusted source, be sure to sanitize it:
new Ajax.Request('/some_url', { method:'get', requestHeaders: {Accept: 'application/json'}, onSuccess: function(transport){ var json = transport.responseText.evalJSON(true); } });
