摘要：實(shí)現(xiàn)對原生物理返回鍵的監(jiān)聽獲取獲取再次返回退出自定義實(shí)現(xiàn)中效果自定義，實(shí)現(xiàn)中效果顯示文字顯示的時間長度

實(shí)現(xiàn)對原生物理返回鍵的監(jiān)聽:

var exitAppTicker = 0;
  document.addEventListener("deviceready",function(){
      document.addEventListener("backbutton", function(){
        var pageUrl = window.location.href;
        var n = pageUrl.lastIndexOf("?");
        var m = pageUrl.lastIndexOf("/");
        var str = ""
        if (n > 0) {
          str = pageUrl.substring(m+1,n); //獲取pageName
        } else {
          str = pageUrl.substring(m+1); //獲取pageName
        }
        if(str == "index" || str == "" || str == "loginPhone"){
            if(exitAppTicker == 0){
                    exitAppTicker++;
                    showToast("再次返回退出", 2000)
                    setTimeout(function(){
                            exitAppTicker = 0;
                    },2000);
            }else if(exitAppTicker == 1){
              navigator.app.exitApp();
            }  
        }else{
            history.back();
        }
      }, false);
  },false);

自定義toast , js實(shí)現(xiàn)android中toast效果

/** 
   * 自定義toast，js實(shí)現(xiàn)android中toast效果
   * @param msg 顯示文字 
   * @param duration 顯示的時間長度 
   */  
  function showToast(msg, duration) {
    duration = isNaN(duration) ? 2000 : duration;    
    var m = document.createElement("div");    
    m.innerHTML = msg;    
    m.style.cssText = "width:60%; min-width:150px; background:#000; opacity:0.5; height:40px; color:#fff; line-height:40px; text-align:center; border-radius:5px; position:fixed; top:70%; left:20%; z-index:999999; font-weight:bold;";    
    document.body.appendChild(m);    
    setTimeout(function() {    
        var d = 0.5;    
        m.style.webkitTransition = "-webkit-transform " + d    
                + "s ease-in, opacity " + d + "s ease-in";    
        m.style.opacity = "0";    
        setTimeout(function() {    
            document.body.removeChild(m)    
        }, d * 1000);    
    }, duration);    
  }
