单击按钮删除计时器

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，如果你按下键，可以回拨弹出窗口。

我的重点是打印＆＃39;按钮。如果打印＆＃39;按钮已被点击，我希望计时器的值永远为0，也就是基本上永远消失。我已经尝试了clearInterval()，但这似乎没有起作用，我找不到任何其他方法来帮助我。

请注意，虽然在我创建HTML文件时它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。请注意，计时器由counter变量控制。我的代码如下：

＆＃13;

＆＃13;

$(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.
}

// 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);

Answer 1

如果我正确理解您尝试执行的操作，那么您希望在单击“打印”时运行clearInterval(setMsg)。 printDiv()是打印按钮单击事件的处理程序，printDiv（）中没有任何地方调用clearInterval(setMsg)。一种方法是创建一个函数来完成所有需要完成的操作以摆脱计时器 - 然后你可以在1）计时器用完时调用它，或者2）点击打印。如果您还不希望在用户回来时显示计时器，那么您必须在printDiv（）函数中的localStorage（或设置cookie）中设置timesVisited。尝试以下内容。我试图简化您设置计数器和存储时间的逻辑，并且还排除了存储的cookie替代方案，以简化调试问题：

＆＃13;

＆＃13;

function printDiv()
{
    endTimer();
    localStorage.setItem('timesVisited', 4);
}

// 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)

// Uncomment below to reset localStorage for testing
//localStorage.removeItem('timesVisited');

if (typeof(Storage) !== "undefined") {
    counter = 60;
    timesVisited = localStorage.getItem("timesVisited");
    if (!timesVisited) {
      timesVisited = 0;
    } else {
      timesVisited++;
    }
    localStorage.setItem("timesVisited", timesVisited);
    counter = Math.max(0,60-(15*timesVisited));  
} 

  function endTimer() {
      $( ".close" ).click(function() {
        $('#PopUp').css("visibility", "hidden"); 
        $('#PopUp').css("opacity", 0);
      });
      $("#timer").remove();
      clearInterval(setMsg);
  }

  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 {
      endTimer();
    }
  }, 1000);
