我有一个弹出窗口，在页面加载时自动加载，它在关闭按钮上有一个计时器，可以防止弹出窗口关闭60秒。它还有一个打印按钮，如果按下按键，可以调用它。
现在，我一直试图让定时器上的时间量变化，这取决于用户已经看过弹出窗口的次数（即第一次：60秒。第二次到第四次：45秒。第五次+时间：30秒。），由counter变量控制。我找到了link1，link2，link3和link4我认为这对我的问题有实际帮助，但我无法将它们合并到我的代码中成功。
请注意，虽然计时器在我的浏览器中有效，但计时器似乎无法在代码段或fiddle中使用。我的代码如下：
$(document).ready(function() {
$(document).keypress(function(e){
if(e.charCode === 65 || 103) {
$('#PopUp').css("visibility", "visible");
$('#PopUp').css("opacity", 1);
}
});
$(function(){
$('#PopUp').css("visibility", "visible");
$('#PopUp').css("opacity", 1);
});
$( ".close" ).click(function() {
$('#PopUp').css("visibility", "hidden");
$('#PopUp').css("opacity", 0);
});
});
function printDiv()
{
var content = document.getElementById('content').innerHTML;
var win = window.open();
win.document.write(content);
win.print(); // JavaScript Print Function
win.close(); //It will close window after Print.
}
var counter = 60;
var setMsg = setInterval(function() {
counter--;
if(counter >= 60 && counter >= 70) {
$("#close-message").html("1:" + (counter - 60));
} else if(counter >= 60 && counter < 70) {
$("#close-message").html("1:0" + (counter - 60));
} else if(counter >= 10) {
$("#close-message").html("0:" + counter);
} else if (counter > 0) {
$("#close-message").html("0:0" + counter);
} else {
$( ".close" ).click(function() {
$('#PopUp').css("visibility", "hidden");
$('#PopUp').css("opacity", 0);
});
$("#timer").remove();
clearInterval(setMsg);
}
}, 1000);
}); .t {

答案 0 :(得分：2)
您可以使用localStorage（不会过期），sessionStorage（会话持续）或Cookie（持续到您设置的过期日期或用户删除它们）。 localStorage和sessionStorage。
以下是使用sessionStorage的代码（如果可用）。如果它不可用，它将回退到使用cookie。如果您想使用localStorage，只需将sessionStorage替换为localStorage。
使用以下代码替换var counter = 60;：
// initialization
var counter = 60;
var timesVisited = 1;
var cookieExpirationDays = 5000; // don't expire cookies for 5000 days
// test to see if localstorage/sessionStorage is available (localStorage has no expiration date)
if (typeof(Storage) !== "undefined") {
counter = 60;
timesVisited = sessionStorage.getItem("timesVisited");
// first time
if ((timesVisited == null) || (timesVisited < 1)){
timesVisited = 1;
sessionStorage.setItem("timesVisited", timesVisited);
counter = 60;
}
// second time
else if ((timesVisited >= 1) && (timesVisited <= 3)){
timesVisited++;
sessionStorage.setItem("timesVisited", timesVisited);
counter = 45;
}
// third time
else if (timesVisited >= 4){
timesVisited++;
sessionStorage.setItem("timesVisited", timesVisited);
counter = 30;
}
}
// No localstorage/sessionStorage. Use cookies
else {
timesVisited = getCookie("timesVisited");
console.log(timesVisited);
// first time
if ((timesVisited == "") || (timesVisited < 1)){
timesVisited = 1;
setCookie("timesVisited", timesVisited, cookieExpirationDays);
counter = 60;
}
// second time
else if ((timesVisited >= 1) && (timesVisited <= 3)){
timesVisited++;
setCookie("timesVisited", timesVisited, cookieExpirationDays);
counter = 45;
}
// third time
else if (timesVisited >= 4){
timesVisited++;
setCookie("timesVisited", timesVisited, cookieExpirationDays);
counter = 30;
}
}
