jquery - jquery继续重定向om倒计时

Question

这是我在 id dlbtn 上触发点击事件时的 jquery 倒计时代码

var settimmer = 0;
$(function() {
    $('#dlbtn').click(function() {
        $('#dlnotify').toggle('slow');
        window.setInterval(function() {
            var timeCounter = $("b[id=show-time]").html();
            var updateTime = eval(timeCounter) - eval(1);
            $("b[id=show-time]").html(updateTime);
            if (updateTime <= 0) {
                window.location = ('/dl.php?fid=12');

                $('#dlnotify').hide();
            }
        }, 500);
        updateTime--;
        return false; //Kill the Event after request
    });

});​

我不是 100% 确定问题是什么，但是为了消除setInterval你需要打电话给clearInterval

试试这个代码：

var settimmer = 0;
$(function() {
    $('#dlbtn').click(function() {
        $('#dlnotify').toggle('slow');
        settimmer =window.setInterval(function() {
            var timeCounter = $("b[id=show-time]").html();
            var updateTime = eval(timeCounter) - eval(1);
            $("b[id=show-time]").html(updateTime);
            if (updateTime <= 0) {

                window.location = ('/dl.php?fid=12');
                clearInterval(settimmer); // clear the interval to avoid multiple redirects 
                $('#dlnotify').hide();
            }
        }, 500);
        updateTime--;
        return false; //Kill the Event after request
    });

});​
