clearetimeout功能不工作如何工作 [英] clearetimeout function not working how to make work

问题描述

iam有两个settimeout函数，第一个将在window.load上执行，我想在第二个settimeout函数被调用时停止第一个计时器iam在按钮点击中调用第二个settimeout事件并且它必须按下另一个停止按钮后停止

first setoutout

iam having two settimeout functions first one will be executing on window.load and i want to stop the first timer when second settimeout function is called iam calling tha second settimeout event in button click and it has to stop after pressing another stop button
first settimeout

window.onload = testSp;
   function testSp() {
       alert("First");
       Timer1 = setTimeout("CheckStatus()", 4000);
   }

var secondsetimeout= function () {
       alert("s");
       clearTimeout(Timer1);
       Timer2 = setTimeout("CheckStatus()", 4000);
       }

并在跟随停止功能时停止秒针

and stoping secondtimer in following stop function

function stop() {
          clearTimeout(Timer2);
          Timer2 = 0;
}

推荐答案

试试这个

try this

<script type="text/javascript">
        var value = 'checkstatus';
        var CheckStatus = function ()
        { alert(value); }
        window.onload = testSp;
        var Timer1, Timer2;
        function testSp() {
            alert("First");
            value = 'first function'
            setInterval(CheckStatus, 4000);
        }
        var secondsetimeout = function () {
            alert("s");
            clearTimeout(Timer1);
            value = 'second function'
            Timer2 = setInterval(CheckStatus, 4000);
        }
        function stop() {
            setInterval(Timer2);
            Timer2 = 0;
        }


    </script>
