I can’t tell you if it’s an error in jquery or IE, but it looks like the XDomainRequest fails in IE. Add this to the URL: &callback=? …so the response will be handled as jsonp. Edit: It looks like Microsoft’s XDOmainRequest is not implemented in jQuery, so you can’t run Cross-Domain-Requests in jQuery using IE(except … Read more
Assuming you mean “file on a local filesystem” when you say .json file. You’ll need to save the json data formatted as jsonp, and use a file:// url to access it. Your HTML will look like this: <script src=”https://stackoverflow.com/questions/6711002/file://c:\data\activity.jsonp”></script> <script type=”text/javascript”> function updateMe(){ var x = 0; var activity=jsonstr; foreach (i in activity) { date … Read more
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: success, error, etc }, “json”); In that call, dataToBeSent could be anything you want, although if are sending the contents of a an html form, you … Read more
Some modern browsers have support for parsing JSON into a native object: var var1 = ‘{“cols”: [{“i” ……. 66}]}’; var result = JSON.parse(var1); For the browsers that don’t support it, you can download json2.js from json.org for safe parsing of a JSON object. The script will check for native JSON support and if it doesn’t … Read more

This is how it worked for me… $.ajaxSetup({ cache: false }); $.getJSON(“/MyQueryUrl”,function(data,item) { // do stuff with callback data $.ajaxSetup({ cache: true }); });
$.getJSON(‘selectMenus.php’, function(data){ var html=””; var len = data.length; for (var i = 0; i< len; i++) { html += ‘<option value=”‘ + data[i].monthId + ‘”>’ + data[i].month + ‘</option>’; } $(‘select.month’).append(html); }); Storing the HTML code in a variable and appending it only once at the end is very important if you care about your … Read more
$.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 … Read more
Your code just needs a trigger for it to be enabled. This will allow you to disable cache in all future ajax $(document).ready(function() { $.ajaxSetup({ cache: false }); }); Hope it helps 🙂
You need to look in to JSONP. Essentially, when you try to load JSON from another domain, it fails because there is a domain boundary you can not cross. To avoid this, you have to PAD it (P in JSONP). Padding it is essentially wrapping it in a function call (where the function name resides … Read more
