clearInterval（）不清除間隔

Question

我想清除按鈕點擊的時間間隔，但它沒有清除間隔，我也嘗試過全局範圍。這裏是我的功能，設置間隔：一個按鈕，我想clearinterval的

/* call idle js */ 
var awayCallback = function() { 
    window.userLog = new Date().getTime(); 
    CheckOtherUserWantsAccess(); 
    console.log(new Date().toTimeString() + ": away"); 
}; 

var awayBackCallback = function() { 
    window.userLog = new Date().getTime(); 
    console.log(new Date().toTimeString() + ": back"); 
}; 

var onVisibleCallback = function() { 
    window.userLog = new Date().getTime(); 
    console.log(new Date().toTimeString() + ": now looking at page"); 
}; 

var onHiddenCallback = function() { 
    window.userLog = new Date().getTime(); 
    CheckOtherUserWantsAccess(); 
    console.log(new Date().toTimeString() + ": on hidden callback"); 
}; 


//this is another way of using it 
var idle = new Idle({ 
    onHidden: onHiddenCallback, 
    onVisible: onVisibleCallback, 
    onAway: awayCallback, 
    onAwayBack: awayBackCallback, 
    awayTimeout: 120000 //away with 120 seconds of inactivity 
}).start(); 
console.log(idle);

的onclick：

<a onclick="clearInterval(interval)" data-dismiss="modal"><i class="fa fa-check" aria-hidden="true"></i> OK</a>

也是一個面向對象的方法可以幫助你以更好地控制您的示波器：

system = { 
    interval :false, 
    showSaveWorkDialog: function(action, blueprint_id){ 
    // ... 
    system.interval && clearInterval(system.interval); 
    system.interval = setInterval(function() { 
     //... 
    }, 1000); 
    }, 
    clickLink: function(){ 
    system.interval && clearInterval(system.interval); 
    system.interval=false; 
    } 
} 


<a onclick="system.clickLink()" ... >

我不知道問題出在哪裏從何而來，我們可能需要一個完整的工作樣本模仿這個問題。

不過，怎麼樣在JS處理您的活動，你可以在你的範圍更好的控制：

(function($) { 
    $(document).ready(function() { 
     var interval; 
     function showSaveWorkDialog(action, blueprint_id) { 
      alert('page Lost Access'); 
      interval && clearInterval(interval); // avoid the previous interval to continue "unhandled" 
      interval = setInterval(function() { 
       console.log("still going"); 
       //... 
      }, 1000); 
     }; 

     $('body').on('click','a.clear-interval', function(e) { 
      console.log(interval) 
      interval && clearInterval(interval); 
      interval = 0; 
      return false; 
     }); 
    }); 
}(jQuery)); 

和鏈接：

<a class="clear-interval" data-dismiss="modal"><i class="fa fa-check" aria-hidden="true"></i> OK</a> 

Answer 3

當您創建間隔時，完整的功能在內部編寫，但是當你嘗試清除它時，需要同樣的東西。 嘗試witht下一個系統：

var interval = setInterval(logtext,1000); 

function logtext(){ 
    console.log("Its working"); 
} 

然後清除它只是使用

clearInterval(interval); 

---

另一個系統，我喜歡使用：

var interval = null; 

    function startinterval(){ 
     if (!interval) { 
     interval = setInterval(logtext,1000); 
     } 
    }; 
    function stopinterval(){ 
     if (interval) { 
     clearInterval(interval); 
     interval = null; 
     } 
    }; 

然後只需使用：

startinteval(); 
stopinterval();
