Question

How can I get the following JavaScript to return row so I can access it outside the transaction? All of Apple’s example code seems to have HTML written to the browser within the transaction instead of ever passing data back to a calling function.

Along the lines of:

function getData() {   db.transaction(function(tx) {     tx.executeSql('SELECT id FROM table LIMIT 1', [], function(tx, result) {       row = result.rows.item(0);     }, function(tx, error) {     });   });    return row; } 

Is this even possible? Can the Webkit storage API be set to synchronous instead of asynchronous execution?

Answer 1

I think you want to create a closure here as values are being garbage collected/moved away from the scope chain before you can access them. Pass row to a closure for access later or to some other function that can handle the value while it’s still in scope.
