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. Tap the marker to display an info window with no contents Press the 'report' button to display the contents in the information window. How can I make sure the content stays intact when I close and reopen the info window?

If continues to run in the background, I think it will be resolved.

javascript code

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);
    }
