Error handling in getJSON calls

How can you handle errors in a getJSON call? Im trying to reference a cross-domain script service using jsonp, how do you register an error method? Luciano Costa $.getJSON() is a kind of abstraction of a regular AJAX call where you would have to tell that you want a JSON encoded response. $.ajax({ url: url, dataType: 'json', data: data, success: callback }); You can handle errors in two ways: generically (by configuring your AJAX calls before actually calling them) or specifically (with method chain). 'generic' would be something like: $.ajaxSetup({ "error":function() { alert("error"); } });

问题 I am using following code to grab data from JSON. $(document).ready(function() { $.getJSON("http://www.example.com/data.php?id=113&out=json", function(data) { $.each(data.issue.page, function(i,item) { imagesJSON[i] = item["@attributes"]; }); alert(imagesJSON.length); }); }); It works in Mozilla, Chrome and other browser but not in IE.

问题 I need to do a getJSON() request, but how do I pass authorisation and custom headers? I am getting issues that the request header is taking the name, but NOT the values.

问题 GOAL: What I'm after is to get data from database and refresh main.php (more evident through draw_polygon) every time something is added in database (after $.ajax to submit_to_db.php). So basically I have a main.php that will ajax call another php to receive an array that will be saved to database, and a json call another php to return an array will be used by main.php. $(document).ready(function() { get_from_db(); $('#button_cancel').click(function(){ $.ajax({ url: 'submit_to_db.php', type:
