推荐答案

您可以用基本的JavaScript使用的的setTimeout ：

You can do this with basic JavaScript using setTimeout:

var totalSeconds = 0

function stopwatch() {
    // increment the seconds
    totalSeconds++;

    // display the seconds to the user
    document.getElementById("<%=myLabel.ClientID%>").innerHTML = "You have spent " + totalSeconds + " on this page.";

    // wait a second and call the timer again
    setTimeout("stopwatch()", 1000);
}

// trigger the timer
timer();

更新：如果用户将是你可能想显示一个稍微人性化的消息，然后同时在页面上你已经花了1000秒此页。 这里有一个快速的JavaScript 功能会秒转换成时间已过。

Update: If the user is going to be on the page for a while you probably want to display a slightly more user-friendly message then "You have spent 1000 seconds on this page". Here's a quick JavaScript function that'll transform the seconds into time elapsed.
