jQuery $.ajax Not Working in IE8 but it works on FireFox & Chrome
ajax, internet-explorer, javascript, jquery, json
Solution
I would comment out the contentType and add dataType: "json"
from http://api.jquery.com/jQuery.ajax/
dataType: The type of data that you're expecting back from the server.
contentType: When sending data to the server, use this content-type.
you are specifying that you are sending json, but you are not - maybe this is the issue?
Problem
I have the following ajax call which works perfectly in Firefox and Chrome but not IE: ``` function getAJAXdates( startDate, numberOfNights, opts ) { var month = startDate.getMonth() + 1; var day = startDate.getDate(); var year = startDate.getFullYear(); var d = new Date(); var randNum = Math.floor(Math.random()*100000000); $.ajax({ type : "GET", dataType : "json", url : "/availability/ajax/bookings?rand="+randNum, cache : false, data : 'month='+month+'&day='+day+'&year='+year+'&nights='+numberOfNights, contentType : 'application/json; charset=utf8', success : function(data) { console.log('@data: '+data); insertCellData(data, opts, startDate); }, error:function(xhr, status, errorThrown) { console.log('@Error: '+errorThrown); console.log('@Status: '+status); console.log('@Status Text: '+xhr.statusText); } }); } ``` I know for a fact that all the variables are passing the right content and $.ajax is indeed passing all the paramater/values. This is what I get on error: LOG: @Error: undefined LOG: @Status: parsererror LOG: @Status Text: OK I'm aware of the cache issue on IE and implemented a random paramater to clear it up. Here is the JSON i get back (i'm able to see it using Charles) ``` { "availability":[ { "inventory_id":"5", "booking_id":"21", "start_date":"05-01-2010", "number_nights":4, "text":"deFrancisco, Martin - $500.00 ACTIVE", "type":"BOOKING" } ] } ``` Finally these are the headers that are sent back from the backend: ``` header('Content-Type: application/json; charset=utf8'); header("Cache-Control: no-cache"); header("Expires: 0"); header('Access-Control-Max-Age: 3628800'); header('Access-Control-Allow-Methods: GET, POST, PUT, DELETE'); ``` Any ideas?
