Question

我有一个弹出窗口，当页面加载时自动加载，它在关闭按钮上也有一个计时器，它的时间根据用户查看弹出窗口的次数而变化。它还有一个“打印”按钮，如果按“g”键，可以调用弹出窗口。

我的重点是“打印”按钮。目前，当我点击“打印”按钮时，它会添加以下代码：

$("#timer").remove();
clearInterval(setMsg);

但是，如果您要重新加载页面，计时器会重新出现，就像根本没有点击按钮一样，它可能是5，15，30，{ {1}}或45秒，具体取决于您之前查看过该网页的次数。我希望在单击“打印”按钮后永久删除计时器。

请注意，计时器似乎无法在代码段或fiddle中使用，因为我认为有些功能无法正常工作，例如60。但是，当我创建HTML文件时，它将在我的浏览器中工作。我的代码如下：

document.write

$(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);
  });
});

// initialization
var counter = 60;
var timesVisited = 0;
var cookieExpirationDays = 7; // don't expire cookies for a week
// test to see if localstorage/sessionStorage is available (localStorage has no expiration date)

if (typeof(Storage) !== "undefined") {
  counter = 60;
  timesVisited = localStorage.getItem("timesVisited");
  // first time
  if ((timesVisited == 0) || (timesVisited < 1)) {
    timesVisited = 1;
    localStorage.setItem("timesVisited", timesVisited);
    counter = 60;
  }
  // second time
  else if ((timesVisited >= 1) && (timesVisited <= 3)) {
    timesVisited++;
    localStorage.setItem("timesVisited", timesVisited);
    counter = 45;
  }
  // third time
  else if ((timesVisited >= 4) && (timesVisited <= 8)) {
    timesVisited++;
    localStorage.setItem("timesVisited", timesVisited);
    counter = 30;
  }
  // fourth time
  else if ((timesVisited >= 9) && (timesVisited <= 13)) {
    timesVisited++;
    localStorage.setItem("timesVisited", timesVisited);
    counter = 15;
  }
  // fifth time
  else if (timesVisited >= 14) {
    timesVisited++;
    localStorage.setItem("timesVisited", timesVisited);
    counter = 5;
  }
}
// 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 <= 8)) {
    timesVisited++;
    setCookie("timesVisited", timesVisited, cookieExpirationDays);
    counter = 30;
  }
  // fourth time
  else if ((timesVisited >= 9) && (timesVisited <= 13)) {
    timesVisited++;
    setCookie("timesVisited", timesVisited, cookieExpirationDays);
    counter = 15;
  }
  // fifth time
  else if (timesVisited >= 14) {
    timesVisited++;
    setCookie("timesVisited", timesVisited, cookieExpirationDays);
    counter = 5;
  }
}
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);
});

        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.
        $( ".close" ).click(function() {

          $('#PopUp').css("opacity", 0);

Answer 1

我有一个弹出窗口，可以在加载页面时自动加载

我非常不喜欢这个，但回到了原点。你想要做的是存储＆＃34;某处＆＃34;单击该按钮，因为单击此按钮仅对前端用户有影响，我相信将其存储在服务器端是没有用的，我会将其保留在Web浏览器中。

有几个选项可以在浏览器中存储临时信息，例如Cookie，但session storage简单而现代，这段代码会检查是否已设置变量：

if (localStorage.getItem("btn_clicked") !== null) {
    // Show the pop-up
}

跟踪按钮被点击的次数
