It looks like that a HEAD request should work. But in my code below, it
doesn't appear that either the error function or the success function get
called. Note that async:true doesn't make any difference.
// Check for application updates
$('input.updatecheck').live('click', function (event) {
var geturl;
geturl = $.ajax({
type: "HEAD",
dataType:"jsonp", //need to use JSONP to get to isriscouch
async: false,
url: '
http://user:[email protected]/ourdb/_design/library',
error:function (){alert("fail!");},
success: function () {
alert("done!"+ geturl.getAllResponseHeaders());
}
});
. . .
});
