当我关闭并重新打开信息 window 时，如何确保内容保持不变

Question

I am outputting the Google Map info window with id created in javascript, but when I close and reopen the info window, there is Disappear content in the info window. 点击标记以显示没有内容的信息 window 按“报告”按钮以显示信息 window 中的内容。 当我关闭并重新打开信息 window 时，如何确保内容保持不变？

如果继续在后台运行，我想会解决的。

javascript码

function display_c(start){
        window.start = parseFloat(start);
        var end = 172800; // change this to stop the counter at a higher value
        var refresh=1000; // Refresh rate in milli seconds
        if(window.start >= end ){
            alert("Time Over ");
        } else {
            mytime=setTimeout('display_ct()',refresh)
        }
    }

    function display_ct() {
        // Calculate the number of days left
        var days=Math.floor(window.start / 86400);
        // After deducting the days calculate the number of hours left
        var hours = Math.floor((window.start - (days * 86400 ))/3600)
        // After days and hours , how many minutes are left
        var minutes = Math.floor((window.start - (days * 86400 ) - (hours *3600 ))/60)
        // Finally how many seconds left after removing days, hours and minutes.
        var seconds = Math.floor((window.start - (days * 86400 ) - (hours *3600 ) - (minutes*60)))

        var x = days + "day " + hours + "hour " + minutes + "minute " + seconds + "second";


        document.getElementById('ct').innerHTML = x;
        window.start= window.start+ 1;

        tt=display_c(window.start);
    }

我知道了

var timer = document.getElementsByClassName('ct');
for (var i = 0; i < timer.length ; i++){
    timer[i].innerHTML = x;
}
