Hi, I was perusing the group looking to help a colleague with a
similar problem.
One thing I noticed here, and maybe this has no bearing at all, was
the difference between the syntax in the first two posts:
jayQuery wrote:
$.getJSON('http://site1:8888/myjson.json?format=json&callback=?', {},
function(data) { alert(data.result); })
Mike Alsup wrote:
$.getJSON('http://site1:8888/myjson.json?format=json&callback=?',
function(data) {
alert(data.result);
});
Those are different from one another. jayQuery passes an empty set of
braces as second argument to getJSON, whereas Mike's passes the data
function as the 2nd argument. Also, jay's overall wrapper function is
not closed with a semicolon.
Not sure if it has any bearing at all, just noting that one says his
works and the other says his doesn't, but they are different.
