您的javascript中存在错误：我在开头添加了以下行：

<body>
<script language="javascript"> 

//Get Year, Month, Date, Hour and Minute to form Strings

    var y = today.getFullYear();
    var YY = y.toString();

    var m = today.getMonth()+1;
    if (m <= 9){
        m = '0' + m;
    }
    var MM = m.toString();

    var d = today.getDate();
    if (d <= 9){
        d = '0' +d;
    }
    var DD = d.toString();

    var h = today.getHours();
    if (h <= 9){
        h = '0' + h;
    }
    var HH = h.toString();

    var mi today.getMinutes();
    if (mi <=9){
        mi = '0' + mi;
    }
    var MiMi = mi.toString();

//Create image file in folder details, using year, month, date, hour and minute Strings
//Image file is in the /public_html folder, year+month+date sub-folder, hour sub-sub-folder,
// prefix with "tbmc_", year+month+date+hour+minutes in-between and ends with "59.jpg"  
// Assgin folder and image file details to a variable F 

    var F = "/public_html/"+YY+MM+DD+"/"+HH+"/tbmc_"+YY+MM+DD+"_"+HH+MiMi+"59.jpg";

//Try to print but nothing happen


<img scr= "F" width="1" height="1">

</script> 

</body>

并更正了这句话：

var today = new Date();

丢失了=的地方。在这里拉小提琴：

函数追加零输入{ return input.toString.length==1？'0'+输入：输入； } //获取年、月、日期、小时和分钟以形成字符串 var today=新日期； var YY=today.getFullYear； var MM=appendZerotoday.getMonth+1； var DD=appendZerotoday.getDate； var HH=appendzeroday.getHours； var MiMi=appendZerotoday.getMinutes； //使用年、月、日期、小时和分钟字符串在文件夹详细信息中创建图像文件 //图像文件位于/public_html文件夹、年+月+日期子文件夹、小时子文件夹中， //前缀为tbmc，年+月+日期+小时+分钟，以59.jpg结尾 //将文件夹和图像文件详细信息关联到变量F var F=/public_html/+YY+MM+DD+/+HH+/tbmc_uu+YY+MM+DD+uuh+MiMi+59.jpg； //尝试打印，但什么也没发生

alertF；有什么问题吗？你试过什么？你会犯什么错误？刷新图像是指覆盖图像还是创建新图像？我不太清楚您的问题，但我认为这些链接可以帮助您我的问题是IMG SRC字符串的格式设置，使用以下代码设法使其正确，但在使用变量显示图像时遇到问题…为什么在内部声明IMG标记？它不应该在外面吗，用HTML？

    var mi = today.getMinutes();
