{{domxref("WindowOrWorkerGlobalScope")}}内置的clearTimeout()方法取消了先前通过调用{{domxref("WindowOrWorkerGlobalScope.setTimeout", "setTimeout()")}}建立的定时器。

- -

语法

- -
scope.clearTimeout(timeoutID)
- - - -

Parameters

- -
-
timeoutID
-
您要取消定时器的标识符。 该ID由相应的setTimeout()调用返回。
-
- -

值得注意的是，{{domxref("WindowOrWorkerGlobalScope.setTimeout", "setTimeout()")}}和{{domxref("WindowOrWorkerGlobalScope.setInterval", "setInterval()")}}使用共享的ID池， 意味着在技术上可以混用clearTimeout()和{{domxref("WindowOrWorkerGlobalScope.clearInterval", "clearInterval()")}} 。 但是，为了清楚起见，你应该避免这样做。

示例

- -

在一个网页中运行如下脚本，并且点击一次页面。一秒钟后你会看见弹出一条信息。如果你在一秒内不停点击页面，弹出框将不再出现。

- -
var alarm = {
-  remind: function(aMessage) {
-    alert(aMessage);
-    delete this.timeoutID;
-  },
-
-  setup: function() {
-    this.cancel();
-    var self = this;
-    this.timeoutID = window.setTimeout(function(msg) {self.remind(msg);}, 1000, "Wake up!");
-  },
-
-  cancel: function() {
-    if(typeof this.timeoutID == "number") {
-      window.clearTimeout(this.timeoutID);
-      delete this.timeoutID;
-    }
-  }
-};
-window.onclick = function() { alarm.setup() };
- -

注意

- -

传入一个错误的 ID 给 clearTimeout()不会有任何影响；也不会抛出异常。
