在 google 分析数据 api 中包含回调的额外参数

function getDataFeed() {
var myFeedUri = 'https://www.google.com/analytics/feeds/data' +
    '?start-date=2009-04-01' +
    '&end-date=2009-04-30' +
    '&dimensions=ga:pageTitle,ga:pagePath' +
    '&metrics=ga:pageviews' +
    '&sort=-ga:pageviews' +
    '&max-results=10' +
    '&ids=' + document.getElementById('tableId').value;

  myService.getDataFeed(myFeedUri, handleDataFeed, handleError);
}

function handleDataFeed(result) {
 // An array of Analytics feed entries.
 var entries = result.feed.getEntries();
 ....
}

我的 javascript 应用程序正在发送具有不同提要参数以及应用程序中不同变量状态的 GA api 请求。由于异步响应，当同时发送多个请求时，处理结果的过程会变得混乱。

有没有办法在请求中包含回调函数（handleDataFeed）的额外参数，该参数可以在处理结果时获取？
或者有其他方法可以解决这个问题，最好不需要创建请求队列。

Consider example code from google analytics api docs:

function getDataFeed() {
var myFeedUri = 'https://www.google.com/analytics/feeds/data' +
    '?start-date=2009-04-01' +
    '&end-date=2009-04-30' +
    '&dimensions=ga:pageTitle,ga:pagePath' +
    '&metrics=ga:pageviews' +
    '&sort=-ga:pageviews' +
    '&max-results=10' +
    '&ids=' + document.getElementById('tableId').value;

  myService.getDataFeed(myFeedUri, handleDataFeed, handleError);
}

function handleDataFeed(result) {
 // An array of Analytics feed entries.
 var entries = result.feed.getEntries();
 ....
}

My javascript app is sending GA api requests with different feed arguments, and different states of variables in my app. Because of async responses, when sending multiple requests simultaneously things get mixed up in handling the results.

Is there a way to include an extra argument to the callback function (handleDataFeed) in the request which can be picked up when handling the results?
Or are there other ways I can solve this, preferably without having to create a queue of requests.

您可以尝试对回调函数使用闭包，以便通过词法作用域可以获得额外的数据：

function getDataFeed() {
    var myFeedUri = 'https://www.google.com/analytics/feeds/data' +
        '?start-date=2009-04-01' +
        '&end-date=2009-04-30' +
        '&dimensions=ga:pageTitle,ga:pagePath' +
        '&metrics=ga:pageviews' +
        '&sort=-ga:pageviews' +
        '&max-results=10' +
        '&ids=' + document.getElementById('tableId').value;

      var extraData = "extra data here";

      myService.getDataFeed(myFeedUri, function(result) {
         // An array of Analytics feed entries.
         var entries = result.feed.getEntries();

         // Extra data still in scope here
         alert(extraData);

         ....
      }, handleError);
    }

You could try using a closure for the callback function so the extra data is available via lexical scoping:

function getDataFeed() {
    var myFeedUri = 'https://www.google.com/analytics/feeds/data' +
        '?start-date=2009-04-01' +
        '&end-date=2009-04-30' +
        '&dimensions=ga:pageTitle,ga:pagePath' +
        '&metrics=ga:pageviews' +
        '&sort=-ga:pageviews' +
        '&max-results=10' +
        '&ids=' + document.getElementById('tableId').value;

      var extraData = "extra data here";

      myService.getDataFeed(myFeedUri, function(result) {
         // An array of Analytics feed entries.
         var entries = result.feed.getEntries();

         // Extra data still in scope here
         alert(extraData);

         ....
      }, handleError);
    }
