问题 I'm using jsonp to do cross-domain comet requests, and the "loading" status is really annoying. Is there any way to suppress this with javascript? For those who are unfamiliar with jsonp, it basically injects a script tag, except in my case, I'm hanging the request on my server without returning the request until a later time.

问题 There's already a solution for writing file JSON online but I want to save json file locally. I've tried to use this example http://jsfiddle.net/RZBbY/10/ It creates a link to download the file, using this call a.attr('href', 'data:application/x-json;base64,' + btoa(t.val())).show(); Is there a way to save the file locally instead of providing a downloadable link? There are other types of conversion beyond data:application/x-json;base64 ? Here's my code: <!DOCTYPE html> <head> <meta charset=

问题 Got kind of a tricky problem. I'm working on a project where we need to allow receipt printouts when users check out on our site at a kiosk.

问题 I have an external web service that in the response body returns json but nested in parentheses, like this: ({"door_x":"103994.001461","door_y":"98780.7862376", "distance":"53.3"}) Using this code: class AddressInfo { String door_x; String door_y; } interface AddressWebService { @GET("/reversegeocoding") AddressInfo reverseGeocoding(@Query("x") double x, @Query("y") double y); } It obviously fails. This is the stacktrace: retrofit.RetrofitError: com.google.gson.JsonSyntaxException: java.lang

问题 but according to this: http://www.php.net/manual/en/function.json-encode.php#94157 it won't. I'm using flot so I need to have an array with numeric indexes returned but what I'm getting is this: jsonp1282668482872 ( {"label":"Hits 2010-08-20","data":{"1281830400":34910,"1281916800":45385,"1282003200":56928,"1282089600":53884,"1282176000":50262,"1281657600":45446,"1281744000":34998}} ); so flot is choking. If I var_dump the array right before I call json_encode it looks like this: array(7) {
