Answer 1

您只需要为请求计时:

var sendDate = (new Date()).getTime();

$.ajax({
    //type: "GET", //with response body
    type: "HEAD", //only headers
    url: "/someurl.htm",
    success: function(){

        var receiveDate = (new Date()).getTime();

        var responseTimeMs = receiveDate - sendDate;

    }
});
