问题 My problem is very simple, I have a file with the name of new.json and I am trying to use JQuery to load and display the data. I have been writing JavaScript code: $.getJSON("new.json", function(data){ // I have placed alert here previously and realized it doesn't go into here $.each(data.streetCity, function(i,s){ alert(s); }); }); } and the data in new.json looks as below: {"streetCity": { "1":"Abergement-Clemenciat", "2":"Abergement-de-Varey", "3":"Amareins" } }; 回答1: If you are using

$.getJSON returning cached data in IE8

I'm playing around with ASP.net MVC and JQuery at the moment. I've come across behavour which doesn't seem to make sense. I'm calling JQuery's $.getJSON function to populate some div's. The event is triggered on the $(document).ready event. This works perfectly. There is a small AJAX.BeginForm which adds another value to be used when populating the divs. It calls the remote function correctly and upon success calls the original javascript function to repopulate the divs. Here is the weird part: In FireFox and Chrome - Everything works. BUT In IE8 (Beta) this second call to the populate Div

I am using a JS object to create graphs with Google visualization. I am trying to design the data source. At first, I created a JS object client-side. var JSONObject = { cols: [{id: 'date', label: 'Date', type: 'date'}, {id: 'soldpencils', label: 'Sold Pencils', type: 'number'}, {id: 'soldpens', label: 'Sold Pens', type: 'number'}], rows: [{c:[{v: new Date(2008,1,1),f:'2/1/2008'},{v: 30000}, {v: 40645}]}, {c:[{v: new Date(2008,1,2),f:'2/2/2008'},{v: 14045}, {v: 20374}]}, {c:[{v: new Date(2008,1,3),f:'2/3/2008'},{v: 55022}, {v: 50766}]}] }; var data = new google.visualization.DataTable

问题 I have the following code that gets the JSON from an array of YouTube video ids. It works great when all the videos exists and the query is successful. It sends several getJSON request, and when all of them are done... the $.when.done() fires and I can process the resulting data. var results = {}, promises = []; $(document).ready(function() { var vids = [ 'ozj2-bnTL3s', 'EAZ4Tlt8MQ4', 'Xn9o7cxqVoA' // ,'this-videoid-doesnot-exists' ], url = 'http://gdata.youtube.com/feeds/api/videos/{{vid}}?v

How to use getJSON, sending data with post method?

由 眉间皱痕 提交于 2019-11-27 02:55:16
I am using above method & it works well with one parameter in URL. e.g. Students/getstud/1 where controller/action/parameter format is applied. Now I have an action in Students controller that accepts two parameters and return a JSON object. So how do I post data with $.getJSON() using post method? Similar methods are also acceptable. The point is to call an action of the controller with AJAX. The $.getJSON() method does an HTTP GET and not POST. You need to use $.post() $.post(url, dataToBeSent, function(data, textStatus) { //data contains the JSON object //textStatus contains the status:

Jquery getJSON populate select menu question

由 纵然是瞬间 提交于 2019-11-27 00:58:25
I am populating a select menu with getJSON. I am wondering if there's a way that I can use jQuery's .each function to bring in these values? Surely there must be an easier way to accomplish this...maybe? PHP file: <?php $queryMonth = "SELECT monthID, month FROM months"; $result = $db->query($queryMonth); while($rowMonth = $db->fetch_assoc($result)) : $data[] = $rowMonth; endwhile; echo json_encode($data); ?> The jQuery: $.getJSON('selectMenus.php', function(data){ $("select.month").append("<option value=" + data[0].monthID + ">" + data[0].month + "</option>"); $("select.month").append("<option
