第一种使用SetInterval:
$(function () { setInterval(ChangeTime, 1000); }); function ChangeTime() { var time; time = $("#time").text(); time = parseInt(time); time--; if (time <= 0) { window.location.href = "/Home/Index"; } else { $("#time").text(time); } }
第二种使用SetTimeout:
$(function () { setTimeout(ChangeTime, 1000); }); function ChangeTime() { var time; time = $("#time").text(); time = parseInt(time); time--; if (time <= 0) { window.location.href = "/Home/Index"; } else { $("#time").text(time); setTimeout(ChangeTime, 1000); } } <div>你访问的页面出现异常,<span>5</span>秒钟自动跳到首页</div>
