Question

I’m making a JSON-P request to an API via jQuery AJAX

$('#fetch').click(function(){
             $.ajax({
                url: 'http://abettertms.com/api2/terms',
                dataType: 'jsonp',                                
                success: function(){
                    console.log("success");
                },
                error: function() { console.log('error'); }
            });
        });

Debugging using the Chrome console shows the ajax request is made to

http://abettertms.com/api2/terms?callback=jQuery1710946886689402163_1328157759295&_=1328157761647

with the extra parameter &_=1328157761647. Why is jQuery adding that? The API I’m calling is my own, so in a crunch I can edit the API to ignore the extraneous parameter, but I’d prefer not having to resort to that.

Answer 1

Cache
Default: true, false for dataType ‘script’ and ‘jsonp’

If set to false, it will force requested pages not to be cached by the browser. Setting cache to false also appends a query string parameter, “_=[TIMESTAMP]”, to the URL.
See cache param in following link.
