您可以存储对该超时的引用，然后在该引用上调用clearTimeout。

// in the example above, assign the result
var timeoutHandle = window.setTimeout(...);

// in your click function, call clearTimeout
window.clearTimeout(timeoutHandle);

// then call setTimeout again to reset the timer
timeoutHandle = window.setTimeout(...);

你必须记住超时“Timer”，取消它，然后重新启动它:

g_timer = null;

$(document).ready(function() {
    startTimer();
});

function startTimer() {
    g_timer = window.setTimeout(function() {
        window.location.href = 'file.php';
    }, 115000);
}

function onClick() {
    clearTimeout(g_timer);
    startTimer();
}

var redirectionDelay;
function startRedirectionDelay(){
    redirectionDelay = setTimeout(redirect, 115000);
}
function resetRedirectionDelay(){
    clearTimeout(redirectionDelay);
}

function redirect(){
    location.href = 'file.php';
}

// in your click >> fire those
resetRedirectionDelay();
startRedirectionDelay();

这里有一个详细的例子，说明到底发生了什么http://jsfiddle.net/ppjrnd2L/

var myTimer = setTimeout(..., 115000);
something.click(function () {
    clearTimeout(myTimer);
    myTimer = setTimeout(..., 115000);
}); 

沿着这条线!

clearTimeout()并提供setTimeout的引用，它将是一个数字。然后重新调用它:

var initial;

function invocation() {
    alert('invoked')
    initial = window.setTimeout( 
    function() {
        document.body.style.backgroundColor = 'black'
    }, 5000);
}

invocation();

document.body.onclick = function() {
    alert('stopped')
    clearTimeout( initial )
    // re-invoke invocation()
}

在这个例子中，如果你没有在5秒内点击body元素，背景颜色将是黑色。

注意:setTimeout和clearTimeout不是ECMAScript的原生方法，而是全局窗口命名空间的Javascript方法。

我知道这是一个老帖子，但我今天想出了这个

var timer       = []; //creates a empty array called timer to store timer instances
var afterTimer = function(timerName, interval, callback){
    window.clearTimeout(timer[timerName]); //clear the named timer if exists
    timer[timerName] = window.setTimeout(function(){ //creates a new named timer 
        callback(); //executes your callback code after timer finished
    },interval); //sets the timer timer
}

你调用使用

afterTimer('<timername>string', <interval in milliseconds>int, function(){
   your code here
});
