success: function(json){
alert(json);
var t = '('+json+')';

});方法三
function page_init() {
try {
$.get("http://fff.ff.com/responsevalue.aspx?cam_id=novell20100608&msg={count}", null, getcallback, 'json');
} catch (e) {}
}
function getcallback(response) {
if (typeof (response) != "object") {
$('#persons').html('0');
return false;
}
if (response.error == 1) {
//alert(response.msg);
$('#persons').html(response.msg);
return;
}}
调用方法：
$(document).ready(
function() {
page_init();
});</script>
