Reading cross domain csv file using JSONP and AJAX - ajax

Question

Trying to read cross domain csv file :
remote_url = “http://www.example.com/buglist.cgi?bug_status=NEW&columnlist=bug_id%2Cshort_desc&query_format=advanced&ctype=csv";
$.ajax({
url:remote_url,
type:"get",
cache: false,
dataType: "jsonp",
success:function(data){
console.log(data);
},
error: function(data){
console.log(data);
}
});
Although getting 200 status from server, It always going into error callback handler and logging a JavaScript syntax error:
SyntaxError: missing ; before statement 6230,"this is a ""short description"", blah blah blah..
My CSV file has two columns “bug_id” and “short_desc” with following values:
bug_id = 6230
short_desc = this is a "short description", blah blah blah..
I know the error is because of double quote in description, but I don’t know the solution. I tried “YQL” to convert CSV to JSON but it returned null as a result, may be because of an error.

The JSONP technique expects the response to be JavaScript. This is why you're getting a JavaScript error; it's trying to execute the CSV content as JavaScript.
JSONP works by defining a callback function in the server, adding a script tag with a URL that tells the server what function it will call, then the server responds with JavaScript that calls that function with the data as a parameter.
The destination URL must support this protocol in other words. You can't just use JSONP for any arbitrary request.
You may need to use a different technique to get your data, like a same-domain proxy that does the HTTP request to the server. If you are able to change the code at example.com, you have even more options.
