javascript - 试图避免在ajaxcall之后滚动条返回开始

Question

我正在使用 FullCalendar，但是当我使用 Ajax 更新作为格式条件的事件的状态时，当我横向滚动调用 ajax 时，滚动条重置为开始，防止查看者站在他想要可视化的位置.

我尝试为包含 Calendar 类的 div 设置固定宽度，没有结果可能我没有设置正确

function ajaxcall1(calendar) {
  $.ajax({
    type: 'GET',
    url: "call for API",
    success: function(doc) {
      successAjax(doc, calendar);
    },
    error: function() {
      console.log("error");
    }
  }).done(function() {
    window.setTimeout(function() {
      ajaxcall2(calendar);
    }, 4000);
  });
}

function ajaxcall2(calendar) {
  $.ajax({
    type: 'GET',
    url: "call for API",
    success: function(doc) {
      successAjax(doc, calendar);
    },
    error: function() {
      console.log("error");
    }
  }).done(function() {
    window.setTimeout(function() {
      ajaxcall1(calendar);
    }, 4000);
  });
}

$(document).ready(function() {
  var calendarEl = document.getElementById('calendar');
  var calendar = new FullCalendar.Calendar(calendarEl, {
    schedulerLicenseKey: 'GPL-My-Project-Is-Open-Source',
    plugins: ['interaction', 'resourceTimeGrid'],

      groupId: 'P56'
    }],
    nowIndicator: true,
    timeFormat: 'H:mm'
  });

  calendar.render();
  ajaxcall1(calendar);
})

successAjax() 的代码

enter code here函数successAjax（文档，日历）{

        allEvents = [];
        $(doc).each(function (idata) {
         $(location).each(function (iloc) {

                    ... Input of Events via API
                    try {

            calendar.getEventSources()[0].remove();

        } catch (err)
        {

        }

        calendar.addEventSource(allEvents);

其余的是改变事件颜色并在特定小时内重新定位多余事件的逻辑
