无法使用jQuery更新URL

我正在开发一个Google Analytics（分析）插件，并且遇到了基于Ajax的分页问题。因为是分页，所以将为每个下一个和上一个链接请求数据。（我解决了；这是一个打字错误。）

我无法正确更新next和previousLink。

我已附上以下屏幕截图和代码。

要求下一个和上一个链接单击的next和previousLink的jQuery代码：

jQuery('document').ready(function(){
    jQuery('.next-page,.prev-page').click(
        function( event ){
            event.preventDefault();

            url = jQuery(this).attr('href');
            console.log( url );
            jQuery.ajax({
                url: url,
                context: document.body
            }).done(function( data ){
                console.log(data.previousLink);
                console.log(data.nextLink);// https://www.googleapis.com/analytics/v3/data/ga?ids=ga:85914642&dimensions=ga:pagePath,ga:date&metrics=ga:pageviews,ga:uniquePageviews,ga:sessionDuration,ga:bounceRate,ga:exits&sort=ga:pageViews&filters=ga:pageViews%3C%3D10&start-date=7daysAgo&end-date=today&start-index=1&max-results=10
                if( data.previousLink != 'undefined' && accessToken != 'undefined' ){
                   // jQuery('.prev-page').prop("href", data.previousLink + '&access_token=' + accessToken );
                    jQuery('.prev-page').attr("href", data.previousLink + '&access_token=' + accessToken );//for first nextlink click and then previous link click http://localhost/analytica-test/wp-admin/undefined&access_token=ya29.RwLlLWsZlGzURfJiOYwkefk_Kpu0XIpKj0XoPHi5_n8nbSdmguInQgLRxXo3Ld0YjdvXeQ
                    //jQuery('.prev-page').href =  data.previousLink + '&access_token=' + accessToken ;
                }
                if( data.nextlink != 'undefined' && accessToken != 'undefined' ){
                   // jQuery('.next-page').prop("href", data.nextLink + '&access_token=' + accessToken );//after first time nextlink is clicked http://localhost/analytica-test/wp-admin/undefined&access_token=ya29.RwJ0guP0f2kr17Jyz8Dqcg0sM7RN4IQpyAehMpniRh8tspbNaIjcUvb2tzPI9ZD8zdG5DQ
                    jQuery('.next-page').attr("href", data.nextLink + '&access_token=' + accessToken );// after first time nextlink is clicked http://localhost/analytica-test/wp-admin/undefined&access_token=ya29.RwLlLWsZlGzURfJiOYwkefk_Kpu0XIpKj0XoPHi5_n8nbSdmguInQgLRxXo3Ld0YjdvXeQ
                    //jQuery('.next-page').href =  data.nextLink + '&access_token=' + accessToken ;
                }
        });
    });
});

重新加载页面时的HTML
