闪现标题栏

Question

我试图得到的标题栏闪光，使用非常基本的HTML。我试过了，但是下面的代码似乎不起作用，我也不知道为什么。另外，有没有一种方法可以使标题栏显示为flash文本，但前提是用户没有查看当前浏览器页面？

我的尝试是：

function Flash() {
            window.setTimeout(function() {
            alert(document.title);
                document.title = (document.title == "Company" ? "Company - flash text" : "Company");
            }, 1000);

            this.stop = function() { 
                document.title = "Company";
                clearTimeout(this.timer);
            }
        }

Answer 1

此make my browser blink as indicator的副本

但既然我现在写了这个脚本：

https://plungjan.name/SO/flashtitle.html

<script>
var timer="";
var isBlurred=false;
window.onblur=function() {
  isBlurred = true;
  timer=window.setInterval(function() {
    document.title = document.title == "Company" ? "Company - flash text" : "Company";
  }, 1000);
}
window.onfocus=function() { 
  isBlurred = false;
  document.title = "Company";
  clearInterval(timer);
}
</script>

jQuery版本并没有太大的不同(但没有经过测试)

var timer="";
var isBlurred=false;
$(window).on("blur",function() {
  isBlurred = true;
  timer=window.setInterval(function() {
    document.title = document.title == "Company" ? "Company - flash text" : "Company";
  }, 1000);
}).on("focus",function() { 
  isBlurred = false;
  document.title = "Company";
  clearInterval(timer);
});

Answer 2

当访问者未查看当前浏览器页面(窗口隐藏、模糊)时，您会询问document.title栏是否闪烁(闪烁)。所以我们必须设置两个函数。首先，我们需要检测浏览器窗口当前是否处于活动状态- visibilityChange(actionFunction)。其次，我们需要开始获取闪烁的条形图- comeBackAlerts()。给你--这个解决方案对我来说很好，希望对你也一样。

/* Set event leaving the page to execute actionFunction */

function visibilityChange(actionFunction) {

  window.focus(); /* window.onfocus = infoIn;  */

  var hidden = "hidden";

  /* Standards: */
  if (hidden in document) {
    document.addEventListener("visibilitychange", actionFunction);
  } else if ((hidden = "mozHidden") in document) {
    document.addEventListener("mozvisibilitychange", actionFunction);
  } else if ((hidden = "webkitHidden") in document) {
    document.addEventListener("webkitvisibilitychange", actionFunction);
  } else if ((hidden = "msHidden") in document) {
    document.addEventListener("msvisibilitychange", actionFunction);
  }
  /* IE 9 and lower: */
  else if ("onfocusin" in document) {
    document.onfocusin = document.onfocusout = actionFunction;
  }
  /* All others: */
  else {
    window.onpageshow = window.onpagehide = window.onfocus = window.onblur = actionFunction;
  }
}


/* Function to make browser window blink in task bar */

var comeBackAlerts = (function() {
  var oldTitle = document.getElementsByTagName('h1')[0].innerText; /* document.title; */
  var msg = "Arbir.ru";
  var intervalId;
  var blink = function() {
    intervalId = setInterval(function() {
      /* document.title = document.title == msg ? ' ' : msg; */
      if (document.title == msg) {
        document.title = oldTitle;
      } else {
        document.title = msg;
      }
    }, 1000);
  };
  var clear = function() {
    clearInterval(intervalId);
    document.title = oldTitle;
    window.onmousemove = null;
    window.onmouseout = null;
    intervalId = null;
  };
  return function() {
    if (!intervalId) {
      blink();
      window.onmousemove = clear;
    }
  };
}());

/* Running the functions */

visibilityChange(comeBackAlerts);
