No need to destroy the dataset - just leave it for when you next want to make a
new request.
//first request
var tempData = new LzDataset();
tempData.setSrc(data.getSrc());
tempData.setQueryString(p);
tempData.doRequest();
//subsequent requests
tempData.setSrc(data.getSrc());
tempData.setQueryString(p);
tempData.doRequest();
A better way to do this might be to use the dataset tag to create a set that
awaits your requests. Then just route all your queries through that, rather
than creating the dataset with script as and when you need to make a request.
So you'd put this tag shortly after your opening <canvas> tag:
<dataset name = "tempData" />
Then whenever you need to do your request -
<method event = "onclick">
tempData.setSrc(your/src/here);
tempData.setQueryString(p);
tempData.doRequest();
</method>
(onclick only an example - adapt this to whatever you like)
Hope that helps.
